Troubleshooting a Dryer That Won't Heat
A dryer that won't heat is a common problem that can be frustrating. But before you call a repairman, there are a few things you can check yourself. This guide will walk you through the most common causes of a dryer not heating and how to fix them.
1. Check the Dryer Vent
The dryer vent is the most common culprit for a dryer that won't heat. Lint buildup in the vent can restrict airflow, preventing the dryer from reaching its full temperature. To check the vent, disconnect the dryer from the power source and unplug it. Then, remove the vent hose from the back of the dryer and inspect it for any blockages. If you find any lint buildup, clean it out with a dryer vent brush or vacuum cleaner.
It's also important to check the vent outside your home. Make sure the vent is clear of any obstructions, such as leaves, debris, or snow. You can also check the vent flap to ensure it's opening and closing properly.
2. Check the Thermal Fuse
The thermal fuse is a safety device that prevents the dryer from overheating. If the thermal fuse blows, the dryer will not heat. To check the thermal fuse, unplug the dryer from the power source and locate the fuse on the back of the dryer. Use a multimeter to test the fuse. If the fuse is blown, you will need to replace it.
3. Check the Heating Element
The heating element is responsible for generating heat in the dryer. If the heating element is faulty, the dryer will not heat. To check the heating element, unplug the dryer from the power source and locate the heating element on the back of the dryer. Use a multimeter to test the heating element. If the heating element is faulty, you will need to replace it.
4. Check the Thermostat
The thermostat controls the temperature of the dryer. If the thermostat is faulty, the dryer may not heat properly. To check the thermostat, unplug the dryer from the power source and locate the thermostat on the back of the dryer. Use a multimeter to test the thermostat. If the thermostat is faulty, you will need to replace it.
5. Check the Door Switch
The door switch is a safety device that prevents the dryer from operating when the door is open. If the door switch is faulty, the dryer may not heat properly. To check the door switch, unplug the dryer from the power source and locate the door switch on the door of the dryer. Use a multimeter to test the door switch. If the door switch is faulty, you will need to replace it.
6. Check the Control Board
The control board is the brain of the dryer. If the control board is faulty, the dryer may not heat properly. To check the control board, unplug the dryer from the power source and locate the control board on the back of the dryer. You can try to reset the control board by pressing the reset button on the control panel. If the reset button doesn't work, you will need to replace the control board.
7. Call a Repairman
If you have checked all of the above components and the dryer is still not heating, it's time to call a repairman. A repairman can diagnose the problem and make the necessary repairs.
Safety Tips
Always unplug the dryer from the power source before working on it.
Be careful not to touch any electrical components while working on the dryer.
