Unlock the mystery: why your kenmore gas dryer has gone cold and how to fix it

Is your Kenmore gas dryer leaving your clothes damp and cold? If so, you’re not alone. This common issue can be frustrating, but it’s often easy to fix. Here are the most common reasons why your Kenmore gas dryer may not be heating, along with step-by-step troubleshooting and repair instructions.

Ignition Issues

Spark Igniter Problems

Problem: The spark igniter fails to create a spark, preventing the gas valve from opening and igniting the burner.

Solution:
1. Unplug the dryer and remove the front panel.
2. Using a multimeter, test the spark igniter for continuity. If there’s no continuity, replace the igniter.
3. Check the wires connected to the igniter for any damage or loose connections. Tighten or replace the wires as necessary.

Gas Valve Problems

Problem: The gas valve fails to open, preventing gas from reaching the burner.

Solution:
1. Turn off the gas supply to the dryer.
2. Remove the front panel and locate the gas valve.
3. Test the gas valve for continuity using a multimeter. If there’s no continuity, replace the valve.
4. Check the wires connected to the gas valve for damage or loose connections. Repair or replace the wires as needed.

Burner Issues

Clogged Burner Ports

Problem: The burner ports become clogged with lint, preventing gas from flowing through and igniting.

Solution:
1. Turn off the gas supply to the dryer.
2. Remove the burner assembly.
3. Use a wire brush or a vacuum cleaner to clean the burner ports.
4. Reinstall the burner assembly and turn on the gas supply.

Faulty Burner

Problem: The burner itself becomes damaged or malfunctioning, preventing it from igniting the gas.

Solution:
1. Turn off the gas supply to the dryer.
2. Remove the burner assembly.
3. Inspect the burner for any visible damage or cracks. If the burner is damaged, replace it.

Thermocouple Issues

Problem: The thermocouple fails to detect the presence of a flame, causing the gas valve to shut off.

Solution:
1. Turn off the gas supply to the dryer.
2. Remove the front panel and locate the thermocouple.
3. Test the thermocouple for continuity using a multimeter. If there’s no continuity, replace the thermocouple.
4. Check the wires connected to the thermocouple for any damage or loose connections. Repair or replace the wires as needed.

Control Board Issues

Problem: The control board fails to send the correct signals to the other components, preventing the dryer from heating.

Solution:
1. Unplug the dryer and remove the front panel.
2. Locate the control board and inspect it for any visible damage or burnt components.
3. If the control board is damaged, it will need to be replaced.

Other Possible Causes

Lint Buildup in the Vent

Problem: Excessive lint buildup in the dryer vent can restrict airflow, preventing the dryer from heating properly.

Solution:
1. Clean the lint trap after every load.
2. Inspect the dryer vent hose for any kinks or blockages.
3. Use a vacuum cleaner to remove lint from the vent hose.

Faulty Temperature Sensor

Problem: The temperature sensor fails to accurately detect the temperature inside the dryer, causing the dryer to overheat or underheat.

Solution:
1. Unplug the dryer and remove the front panel.
2. Locate the temperature sensor and test it for continuity using a multimeter.
3. If the temperature sensor is faulty, replace it.
