10 Common Frigidaire Microwave Problems

Shared below are the most typical Frigidaire microwave issues for DIY troubleshooting:

1. Frigidaire Microwave Not Working – Troubleshooting

Something must be amiss if your microwave is not responsive when you power it on. In most cases, here are the issues to check:

  • Lack of power – Your microwave won’t start without power. Hence, check for issues like a power outage, loose or damaged power plug, tripped breaker, or a non-working socket.
  • Blown-up fuse – If the line or thermal fuse is blown-up, the microwave may fail to start. Generally, these fuses blow up sacrificially during a power surge to safeguard the microwave.
  • Defective door switch – The microwave will read the door as faulty if it’s not well latched and will thus not run. That may happen if the door switch is defective.
  • Defective switch holder – If the door switch holder is misaligned or damaged, the door switch may malfunction, and when it does, the door won’t latch properly. Ultimately, that’ll stop the microwave from running.
  • Malfunctioning thermostat – A malfunctioning thermostat relays the wrong signal to the microwave’s main control board, and at times, the information may stop the microwave from running.
  • Non-working main control board – Nothing works when the main control board is defective. So, if your microwave is non-responsive, it could be due to a non-working control board.

Fix

Before anything, you should reset your microwave, and here’s how to perform the Frigidaire microwave hard reset:

  • Unplug the microwave from the wall socket
  • Wait for 5 minutes to plug it back in
  • Restart it

If the microwave doesn’t start after the reset, check if it has power. That means ruling out a blackout and checking with a multimeter (View on Amazon) if the fuses, door switch, and thermostat have continuity. If they don’t, replace them.

If the switch holder is misaligned or damaged, replace it, and if none of the fixes works, replace the main control board.

Frigidaire Microwave Not Working After Power Outage

Sometimes the Frigidaire microwave won’t work after a power outage. It could be that the power cable is loose, the GFCI or circuit breaker is tripped off, the fuse is blown-up, or the door is open.

Fix

Ideally, a hard reset (shared above) will work and get the microwave working. If it doesn’t, check if the power cable is loose and firmly fix it.

Then inspect the GFCI and circuit breakers and reset them and check with a multimeter if the fuse is defective, and replace it.

If the door is not well-latched, try latching it, and if it doesn’t, check out the issues shared below under a non-closing door.

2. Frigidaire Microwave Not Heating

The microwave should be able to warm your food. If it doesn’t, then something is wrong. In the case of a non-heating Frigidaire microwave, consider these issues:

  • Lack of power – You can’t expect your Frigidaire microwave to heat up if it doesn’t have power. So, check its power supply (as shared above) to ensure it’s turned on.
  • Locked panel – If the Child Lock function is on, it locks the control panel, preventing the microwave from running. So, this could be why your microwave is cold.
  • Incorrect setting – If you choose the wrong timer setting or power level, the microwave may fail to heat up.
  • Unlatched door – Since an unlatched door stops the microwave from running (as shared above), it also prevents it from getting hot.
  • Component failure – Your Frigidaire microwave won’t get hot due to a defective magnetron, diode transformer, or main control board. A microwave expert can help you check them.

Fix

Use the earlier tips to ensure the microwave has power. If Child/Safety Lock is on, disable it and adjust the timer setting and power level accordingly.

Meanwhile, try to firmly secure the door if it’s open and remove any obstruction while at it. If the door doesn’t latch, inspect the door switch with a multimeter and change it if it lacks continuity.

However, if you can’t fix it, call a microwave expert to check components like the magnetron, diode transformer, or main control board for failure and replace them.

3. Frigidaire Microwave Not Spinning (Turntable Not Turning)

Your microwave’s turntable must turn to uniformly warm up food. Sometimes, however, the turntable won’t turn, and if so, check out these issues:

  • The turntable could be off –  If the turntable setting is not turned on, it won’t spin. This setting usually is on by default, waiting for you to start the microwave.
  • Obstructed turntable – If there is debris or any obstruction around the turntable, it’ll prevent it from spinning.
  • Defective turntable motor – The turntable motor could also be faulty, and if it is, then it won’t rotate, and that stops the turntable from spinning.
  • Damaged control panel, roller guide, or tray-drive coupling – If any of the three microwave components are damaged, they can stop the turntable from turning.

Fix

First, check if the turntable setting is off (use the manual) and turn it on. If there are obstructions around the turntable, clear them, and if the turntable motor won’t spin, replace it.

Then inspect the control panel, roller glide, and tray-drive coupling for damage and replace it if that’s the case.

4. Frigidaire Microwave Not Showing Time

A properly working Frigidaire microwave always shows time. If the clock is not displaying, it could be due to:

  • Lack of power – If the microwave lacks power, it won’t turn on, and the display will stay blank.
  • Defective display board – If the display board is faulty, the microwave will have a partial display. So you may not see the time.
  • Defective main control board – While a defective display translates to a partial display, a faulty main control board translates to a blank display.

Fix

Use the earlier tips to ensure your microwave has power. If the display is only partial, replace the display board. But if it’s totally blank and the microwave has power, replace the main control board.

5. Frigidaire Microwave Not Beeping

You expect your Frigidaire microwave to beep at the end of the cycle, during a power outage, or when you open the door mid-cycle. That, however, may not happen due to these issues:

  • Active silent or energy-saver mode – If the silent or energy-saver mode is on, the microwave won’t beep. It just goes mute.
  • Defective display control board – If the issue is not setting-related, it’s likely a faulty display control board, which is a part of the control panel.

Fix

Disable the silent or energy-saver mode if any of them is active. And if that’s not the case, replace the control panel to fix the display control board issue.

6. Frigidaire Microwave Not Closing

The microwave will only start if its door closes. Some issues, however, may prevent the door from closing, and they include the following:

  • Debris clogging – If there is too much debris around the door, it may stop it from closing.
  • Broken door latch – If the door latch is broken, it won’t firmly engage the door, and the door will therefore fail to close.
  • Defective door switch – If the door switch is faulty, it’ll fail to engage the door lock, and consequently, the door won’t shut.
  • Shattered torso spring or door hinge – If the torso spring or the door hinge is damaged, the door won’t shut.

Fix

Clean any debris around the microwave door, and if the door latch is broken, replace it. Meanwhile, check with a multimeter if the door switch has continuity and replace it. And if the torso spring or door hinge is broken, replace it.

7. Frigidaire Microwave Not Turning Off  – Troubleshooting

It’s pretty unusual for the Frigidaire microwave to run non-stop. If it won’t turn off while the door is open, the issue is often a defective door interlocking switch. However, if it doesn’t turn off while the door is shut, the problem is primarily a faulty control board.

Fix

Consider replacing the door interlocking switch if the microwave won’t turn off while the door is open. And if it runs non-stop while the door is shut, replace the control board.

8. Frigidaire Microwave Buttons Not Working

The microwave is inoperable if the buttons are non-responsive. That could happen due to these issues:

  • Lack of power – If the microwave lacks power, the buttons will be non-responsive.
  • Locked panel – If Child Lock is active, it locks the control. So they’ll become non-responsive save for the power button.
  • Defective control panel or main control board – If some buttons are responsive, the control panel is highly likely bad. And if all the buttons are non-responsive and the microwave has power, the main control board is likely defective.

Fix

Check if the microwave has power and use the earlier tips to power it. If some of the buttons are responsive, replace the control panel. However, replace the main control board if all the buttons are non-responsive despite the microwave having power.

9. Frigidaire Microwave Keeps Blowing Fuse – Troubleshooting

It’s odd for the microwave to keep blowing its fuse. That often points to one of these issues:

  • Power surge/fluctuation – If the electricity keeps surging, it could blow up the fuse each time.
  • Circuit overload – The microwave requires a dedicated circuit. Combining it with other appliances may cause a circuit overload, which could blow up the thermal fuse.
  • Defective door switch – If the door switch is faulty, it may cause the fuse to blow up repetitively.
  • Wrong fuse – The correct fuse replacement is essential, as the wrong one could blow up.
  • Wrong fuse installation – Getting and installing the fuse correctly is essential. An incorrect installation could be why the fuse blows up.

Fix

Call an electrician to check and fix any electrical or power issues. Meanwhile, replace the door switch if it fails to show continuity when you examine it with a multimeter. Additionally, ensure you pick the correct fuse replacement and install it properly.

10. Frigidaire Microwave Keeps Tripping Breaker

A microwave will keep tripping the circuit breaker for the same reasons it’ll blow up the fuse. That includes a power surge, circuit overload, and a defective door switch. In addition to that, the breaker will keep tripping if the turntable motor is faulty.

Fix

Call an electrician to check and fix any power issues and replace a defective door switch and turntable motor. You can test both with a multimeter to see if they are faulty.

How can I test the thermoprotector for continuity?

To test the thermoprotector for continuity and determine if it’s functioning properly, you can follow these steps:

1. Start by disconnecting the power supply to ensure your safety while working on the thermoprotector.

2. Obtain a reliable multimeter, preferably one that has a continuity testing feature. This tool will help you accurately measure the electrical continuity of the thermoprotector.

3. Set the multimeter to the continuity or resistance mode. This mode allows you to test the flow of electrical current through the thermoprotector.

4. Locate the thermoprotector within the appliance or circuit. It is usually small and can be found near the heating elements or motor.

5. Carefully remove any covers or panels that may be obstructing access to the thermoprotector. Exercise caution throughout the process to prevent any damage to the component or surrounding parts.

6. Once you have a clear view of the thermoprotector, visually inspect it for any signs of damage such as burns, cracks, or excessive discoloration. If you notice any of these issues, it is a strong indication that the thermoprotector needs replacement.

7. Touch the meter leads or probes to the terminals of the thermoprotector. Ensure that the leads make good contact with the terminals to obtain accurate readings.

8. Observe the multimeter display. If the thermoprotector has continuity, it means that electrical current can pass through it, indicating that it is functioning correctly. On the other hand, if there is no continuity, it suggests that the thermoprotector is likely faulty and needs replacement.

9. If the thermoprotector does not have continuity and cannot be reset, it is essential to replace it. Contact the manufacturer or consult the appliance’s manual for information on obtaining a suitable replacement part.

Remember, when working with electrical components, always prioritize safety. If you are unsure or uncomfortable with conducting these tests, it is advisable to seek professional assistance from a qualified technician.

How can I test the thermostat for electrical continuity?

To test a thermostat for electrical continuity, you can follow these steps:

1. Start by ensuring that the power supply to the thermostat is turned off. This is essential for safety reasons.

2. Locate the thermostat and carefully remove its cover to access the internal components.

3. Check for any visible signs of damage or loose connections. If any components are visibly damaged, it may be necessary to replace the entire thermostat.

4. Using a multimeter set to measure continuity or resistance, carefully touch the meter’s probes to the terminals of the thermostat. Ensure that the probes make good contact with the terminals.

5. If the multimeter displays continuity or a low resistance reading (usually close to 0 ohms), this indicates that the thermostat is functioning correctly and has electrical continuity.

6. However, if there is no continuity or the resistance reading is infinite (usually displayed as “OL” or “1”), it suggests that the thermostat does not have electrical continuity.

7. If the thermostat lacks continuity and cannot be reset or repaired, it is recommended to replace it.

Remember to always adhere to proper safety precautions when handling electrical components and ensure that the power is disconnected before attempting any repairs or tests. If you are unsure or uncomfortable performing these steps, it may be best to consult a professional technician.

What should I check if the electrical outlet is not providing power to the microwave?

Is there anything else I can do to troubleshoot power issues with the outlet?
If you have access to another electrical outlet nearby, you can try plugging the microwave into that outlet to see if it receives power. This will help determine if the issue is specific to the outlet or if there might be a problem with the microwave itself. If the microwave works when connected to a different outlet, then the original outlet is likely the problem and further inspection or repairs may be needed.

Can I fix the power problem with the outlet on my own?
While checking the circuit breakers and fuses is a simple task, attempting to fix electrical wiring or complex issues on your own can be dangerous. It is advisable to seek the help of a qualified electrician to ensure proper and safe resolution of the power problem with the outlet.

What if the circuit breakers and fuses are fine, but the outlet still does not have power?
If the circuit breakers and fuses seem to be in proper working condition, but the outlet is still not receiving power, it is recommended to contact a qualified electrician. There might be an issue with the wiring or a more complex electrical problem that requires professional assistance to diagnose and fix.

What should I do if the outlet is not getting power?
If the outlet is not getting power, you should check the home circuit breakers or fuses. Locate the circuit breaker panel or fuse box in your home and check if any breakers are tripped or any fuses are blown. Reset any tripped breakers or replace any blown fuses to restore power to the outlet.

How can I determine if the electrical outlet is getting power?
To check if the electrical outlet is receiving power, you can try plugging something else, such as a lamp or phone charger, into the outlet. If the other device does not receive power, it indicates that the outlet is not getting power.

If you find that the electrical outlet is not providing power to your microwave, there are a few steps you can take to troubleshoot the issue. First, refer back to the earlier tips provided to ensure your microwave has power. These tips may include checking if the power cord is securely plugged into the outlet and making sure the microwave is properly turned on.

In addition to these initial checks, it is important to thoroughly assess the situation to identify the root cause of the power problem. One effective way to do this is by testing the outlet with another electrical device. Plug in something else, such as a lamp or a phone charger, into the outlet to see if it receives power. If the other device also does not work, it indicates that the outlet itself is not receiving power.

If the outlet is not getting power, the next step is to examine the home circuit breakers or fuses. Sometimes, a tripped breaker or a blown fuse can be the culprit behind the power issue. Locate the circuit breaker panel or fuse box in your home and check if any breakers have been tripped or if any fuses are blown. If you find any, reset the breaker or replace the fuse accordingly.

By following these thorough steps, you can effectively troubleshoot and identify the cause of the power problem if the electrical outlet is not providing power to your microwave.
