Dryer is turning the drum but there is no heat to dry the clothes. This fault can be caused by a multitude of different components that may have failed. It can also be the result of a clogged dryer vent hose. Follow the steps in order below to fix your dryer that will not heat. NOTE: If you live in an older home, you may have a fuse box. Check to be sure the issue you are having is not being caused by a blown fuse.
Clothes Dryer Troubleshooting:
1. CHECK DRYER CONTROLS
Check that the dryer is not on “AIR FLUFF” mode.
If your dryer is on the correct setting then move to step 2.
2. CHECK AIR FLOW/VENT
Check to be sure dryer vent hose is not clogged and restricting airflow. If so, how to clean dryer vent hose.
If your dryer vent hose is not clogged and the dryer is able to properly vent out the air move to step 3.
3. CHECK POWER
Be sure you know how to use a multimeter to check for power before attempting this.
Remove power by unplugging the dryer cord from the wall.
Check for 220/240V across the two hot legs.
Check for 110/120V from neutral to each hot leg.
If you have the correct power voltage going to your dryer then move to step 4.
4. CHECK COMPONENTS
Remove power by unplugging the dryer cord from the wall before testing for continuity.
Thermal fuse – check for continuity
Thermal cutoff – check for continuity
Heating element – check for continuity
Operating thermostat – check for continuity
High limit thermostat – check for continuity
How to use a multimeter to check for continuity
When you check continuity on the above parts, remove a wire from the part so you do not read back through a different path.
If everything above has tested OK, then look for the wiring diagram that should be inside the control panel or find your service manual. This will tell you if certain contacts should be open or closed during different drying cycle settings.
Note: The troubleshooting method above will work on all electric dryers. Maytag, Whirlpool, Samsung, GE, LG, Roper, Frigidaire, Kenmore, Bosch, Hotpoint, Haier, Fisher & Paykel, Electrolux…
