Dryer Won't Heat? All the Easy Fixes You Need to Know
There are multiple issues that can prevent your dryer from heating to the appropriate temperature or to not heat at all. These issues can range from basic maintenance to more complex problems that involve electronic or mechanical components. No matter the issue, diagnosing and repairing the problem is easy with a little elbow grease and some helpful hints from our friends at Sears Parts Direct.
Perform Basic Maintenance
By keeping up with regular maintenance, you can not only prevent more complicated issues from occuring, but also extend the life of your appliance. Be sure to clean trapped lint from the exhaust tube and check inside the drum for clogged air vents that can prevent warm air from properly circulating throughout the interior.

Replace the Dryer Gas Valve Coils
In order to safely ignite the burner and maintain the appropriate temperature throughout a drying cycle, your gas dryer needs to have functional solenoid coils. If your dryer heats briefly but ends before the cycle is finished, a fualty gas valve coil could be the culprit.

Replace the Dryer Heating Element
The heating element is one of the most important components of your gas or electric dryer. This will likely be the culprit if the appliance runs but is not supplying heat. If your dryer is powered and all other components are in good working order, there's a chance that the heating element could be damaged and needs to be replaced.

Repair or Replace the Dryer Electronic Control Board
The electronic control board is the command center of your dryer. Problems with the control board can be difficult to pinpoint and require more expertise to fix than other common repairs. If you think this may be the problem with your appliance, it's recommended that you have it professionally repaired.

Replace the Dryer Thermal Cut-off Fuse
The thermal cut-off fuse helps to prevent your dryer from overheating as it drys. If the thermal cut-off fuse is triggered due to high heat or another malfunctioning component, it cannot be reset and must be entirely replaced.

Another component that can cause the burner in your gas dryer to malfunction is the flame sensor. This component needs to trip in order for the burner to light and heat the contents of the dryer drum.

Replace the Dryer Igniter
The dryer igniter works in conjunction with the flame sensor and gas valve coils to complete the burner ignition sequence. If the igniter cannot become hot enough to complete the cycle, it needs to be replaced.

Replace the Dryer Operating Thermostat
Otherwise known as the cycling thermostat, the dryer operating thermostat ensures that your dryer is running at the appropriate temperature throughout each cycle. If the operating thermostat is broken or malfunctioning, it cannot properly regulate the heating element of an electric dryer or the burner of a gas dryer.

Replace the Dryer Thermistor
Like the operating thermostat, the thermistor helps to regulate the temperature of the drying cycle. Most modern dryers will display a fault code if this component is permanently broken, but a malfunctioning thermistor can prevent the dryer from heating properly while still allowing it to run.

Replace the Dryer Heater Relay
A broken or malfunctioning heater relay will prevent the heating component from igniting in a gas model or engaging in an electric model. Like with some other components, a broken dryer heater relay will not prevent the dryer from running, but will not heat the contents thoroughly.
