Check the Igniter

If your Kenmore 90 Series Gas Dryer is not heating up, the igniter could be the culprit. The igniter is responsible for igniting the gas in the dryer. When you turn on the dryer, the igniter should glow for a few seconds before the gas valve opens, allowing the burner to ignite. If the igniter is faulty or worn out, it may not glow and thus not ignite the gas, causing the dryer to not heat up.

To inspect the igniter:

1. Unplug the dryer from the power source.
2. Locate the igniter, which is typically located on the burner assembly.
3. Visually inspect the igniter for any signs of damage or wear and tear. If the igniter is cracked or broken, it needs to be replaced.
4. If the igniter appears to be in good condition, use a multimeter to test its continuity. If the multimeter does not show continuity, the igniter needs to be replaced.

Replacing the igniter requires disassembling the dryer, which can be a complex process. If you are not comfortable doing it yourself, it is best to consult a professional technician.

Test the Thermal Fuse

If your Kenmore 90 Series Gas Dryer is still not heating up, it’s time to test the thermal fuse. This safety device is responsible for shutting off the heating element if the dryer overheats. A blown thermal fuse will prevent your dryer from heating up, so it’s crucial to test it to see if it needs to be replaced.

Here are the steps to test the thermal fuse:

1. Unplug your dryer and locate the thermal fuse. It’s typically located on the blower housing or exhaust duct.
2. Remove the thermal fuse from the dryer.
3. Using a multimeter, test the thermal fuse for continuity. Set the multimeter to the RX1 setting and touch the probes to the thermal fuse’s terminals. If the multimeter shows a reading of infinity, the thermal fuse is blown.
4. If the thermal fuse is blown, it will need to be replaced. Use a replacement thermal fuse that is compatible with your Kenmore 90 Series Gas Dryer model.
5. Reinstall the new thermal fuse and plug the dryer back in.

Testing and replacing the thermal fuse is a relatively simple process that can potentially solve the issue of your Kenmore 90 Series Gas Dryer not heating up. If this doesn’t resolve the issue, it’s recommended to consult a professional for further assistance.

Inspect the Gas Valve Solenoids

If your Kenmore 90 Series Gas Dryer is still not heating up, it is time to inspect the gas valve solenoids.

The gas valve solenoids control the flow of gas to the burner assembly in your Kenmore 90 Series Gas Dryer. Over time, they may become defective and prevent the dryer from heating up. Test the solenoids for continuity using a multimeter. If they are not working correctly, replace them with new ones to restore heating functionality.

Here is a step-by-step guide to testing the gas valve solenoids:

1. Unplug your dryer and turn off the gas supply.
2. Remove the front panel and locate the gas valve coils attached on top of the gas valve.
3. Disconnect the wires from the solenoid coils.
4. Using a multimeter, set it to measure resistance and touch its probes to the terminals of the solenoids.
5. Check the measurement against the range specified in the dryer’s manual. If the reading is outside of the recommended range, the solenoids are bad and need to be replaced.
6. If the reading is within the proper range, test the continuity of the solenoids by flipping the probes. If there is no reading, the solenoids are faulty and need to be replaced.

By following these steps, you can avoid unnecessary repair bills and get your Kenmore 90 Series Gas Dryer heating up again in no time.

Check the High-Limit Thermostat

If your Kenmore 90 Series Gas Dryer is not heating up, you may need to check the high-limit thermostat. This safety device cuts off the heating element if the dryer overheats, which can cause the dryer to not get hot. Use a multimeter to test the thermostat for continuity. If it is faulty, replace it with a new one to restore heating functionality.

It’s important to note that the high-limit thermostat is not the only safety device in your Kenmore 90 Series Gas Dryer. The thermal fuse and cycling thermostat also play a crucial role in preventing overheating and ensuring safe dryer operation.

If you have determined that the high-limit thermostat is the issue, it’s essential to replace it promptly to prevent any potential safety hazards or damage to your dryer.

Examine the Cycling Thermostat

The cycling thermostat is responsible for regulating the temperature in your Kenmore 90 Series Gas Dryer. It works by turning the heating element on and off to maintain the desired temperature. If it is not functioning correctly, the dryer may not heat up.

To examine the cycling thermostat, first, unplug your dryer and disconnect the thermostat from the wiring harness. Using a multimeter, test the thermostat for continuity. If it does not have continuity, it is faulty and needs to be replaced.

You can purchase a new cycling thermostat from a local appliance store or online retailer. Once you have the replacement thermostat, connect it to the wiring harness and reassemble the dryer.

If replacing the cycling thermostat does not solve the issue of your Kenmore 90 Series Gas Dryer not heating up, continue with the remaining troubleshooting steps.
