These very quick and simple repairs are ones that even the novice do-it-yourselfer can do.
Easy repairs if your dryer won't heat
Several parts on a dryer work together to produce the heat to dry clothes. A problem with any of them could keep the dryer from heating air, even though the dryer comes on.
Electric heating element in an electric dryer
The heating element in an electric dryer is the first thing to check if the dryer won't heat. If the heater coil is broken or burned out, the heating element won't heat.
We have instructions on this easy repair in our DIY repair guide How to replace a heating element in an electric dryer.
Thermal cut-off kit in an electric dryer
The thermal cut-off fuse is a safety device attached to the heater box that shuts off the heater if the dryer overheats. The dryer can overheat if the high-limit thermostat fails.
Replace both parts, which come in a kit. See our DIY repair guide How to install a thermal cut-off fuse kit in an electric dryer for replacement instructions.
A gas dryer also has a thermal cut-off fuse. It works in a similar fashion, shutting down the gas burner if it overheats. The repair is simple following the instructions in our DIY repair guide How to install a thermal cut-off fuse kit in a gas dryer.
Thermal fuse in a gas dryer
The thermal fuse, not to be confused with the thermal cut-off fuse, is located on the gas dryer’s blower housing. The burner won’t ignite if the thermal fuse fails. The most common cause for failure is poor airflow. Instructions for how to fix the issue are in our DIY repair guide How to replace a thermal fuse in a gas dryer.
Easy repairs if your dryer won't start
A number of things could prevent a dryer from starting. Once you make sure that the problem isn't a lack of power to the dryer, check out these repair guides for help.
Thermal fuse in an electric dryer
Unlike in a gas dryer, the failure of the thermal fuse in an electric dryer will prevent the dryer from starting at all. The reasons for the failure, as well as the instructions on how to fix it are the same as in an electric dryer and are in our DIY repair guide How to replace a thermal fuse in an electric dryer.
The push-to-start switch should do exactly as it says—start the dryer when you push it. If the push-to-start switch fails, the dryer won't start when you push the switch or could start even if you don't push the switch.
Follow the instructions in our DIY repair guide How to replace a dryer push-to-start-switch.
Dryer door switch
The dryer door switch lets the control board know when the door is open or closed. If the door switch stops working, the dryer won't start.
If the dryer has a light in the drum, an easy way to tell if the switch is the problem is to open the door and press the switch lever. If the light doesn't come on, the switch is bad. Our DIY repair guide How to replace a dryer door switch shows how to fix this problem.
If your gas dryer won't heat, a broken flame sensor is one possible cause. This guide and video explain how to replace a dryer flame sensor.
The heating element in an electric dryer generates the dryer's heat—it's one of the first things to check if the air in the dryer doesn't get warm. If it's damaged, this repair guide will show you how to replace the heating element.
Numerous components could be to blame for no heat in the dryer. Diagnose and fix the problem.
Check these three things if your gas dryer won't start or run.
