Why Is My GE Microwave Not Heating or Turning?

Generally, a GE microwave won’t heat up or rotate due to different issues. The most notable ones include the following nine:   

1. Failed Power Supply

Your GE microwave needs power to run and get hot. If there’s a disruption, your microwave won’t run or heat up. Overall, here are things to check if your GE microwave doesn’t have power:

  • Is the power cord loosely fixed into the socket?

  • Is the circuit breaker tripped?

  • Or is the thermal fuse blown up?

If you answered YES to any of the three questions, your microwave isn’t heating up or turning due to a power supply failure.


Firmly plug the microwave’s power cord into the wall socket if that’s not the case. If the circuit breaker is tripped up, reset it.

Meanwhile, observe the thermal fuse for signs of burning and replace it if that’s the case. Alternatively, test the fuse with a multimeter. The absence of continuity confirms its faultiness.

2. Wrong Setting

Your GE microwave won’t heat up or turn unless you pick the correct setting, mode, or power level. For example, if you opt for a lower setting or power level, the microwave will fail to get hot.

For example, you can’t expect the microwave to heat frozen food when using the ‘keep warm’ setting. It just won’t work, as it’s a low-heat setting.


Double-check your GE microwave’s setting, mode, and power level to ensure it can heat up and turn the turntable.

3. Wrong Food Choice

Sometimes, a microwave wouldn’t run or heat up, not because something is wrong with it but because the food is not microwave-friendly. For example, if you heat dry foods such as nuts, the appliance might fail to run.


Ensure you only put microwave-friendly foods. Don’t heat non-microwave-labeled foods.

4. Incorrectly-Placed Turntable

If the turntable is out of its track, it won’t turn and may prevent the microwave from heating up. The same could also happen if the turntable is upside down. Thus, it’s essential to inspect it.


Ensure the turntable is on its track. If it’s not, correctly position it there before running the microwave. Also, if the turntable is upside down, place it correctly.

5. Obstructed Turntable

The turntable may also fail to spin due to an obstruction. It could be that some food residue or dirt is underneath, therefore stopping the turntable from turning.


Take out the turntable and clean under it. Ensure you get rid of food residues and dirt before placing the turntable back and running the microwave.

6. Faulty Door Switch

Is the microwave door firmly latched? Consider latching it if it’s not. And if it doesn’t lock, the door switch is likely faulty.

Remember, your GE microwave won’t run if the door is not latched correctly, and if the door switch is at fault, you should replace it.


Test the door switch with a multimeter. If it has no continuity, replace it, as it’s highly likely the reason your microwave door won’t shut.

7. Burnt Diode

The diode is responsible for converting the transformer’s AC power to DC and doubling the voltage output to an amount that’s enough to power the magnetron. The magnetron has to be powered for the microwave to heat, but that doesn’t happen if the diode is bad.


Since the microwave stores large amounts of lethal electricity even when unplugged, it’s not advisable to try and replace the diode. So, it’s good to all a dishwasher expert here.

8. Burnt Magnetron

As mentioned, the magnetron heats the microwave and relies on the diode’s power. Once it gets power from the diode, it generates heat frequencies that heat your food.

So, if the magnetron is burnt, the microwave won’t get hot and will therefore fail to warm food.


The magnetron, just like the diode, can be too dangerous to replace. For that reason, you should involve a microwave expert.
