Our dryers are a modern convenience that we used to take for granted, and don’t think much about. But, when our dryer breaks down and we can’t access clean and dry clothing, the essential role of the dryers becomes painfully clear. Veyr often, a dryer breakdown involves a lack of heat. Your dryer will turn on and off, and cycle normally, but it’s not heating at all. There are many reasons for this problem, and we’ve outlined ten of them here!
Why your Dryer Won’t Heat
1) Blown Thermal Fuse: Your dryer includes a part called a thermal fuse which will blow if your dryer becomes overheated. This prevents the entire unit from being destroyed. If you’ve blown a thermal fuse, your dryer is likely clogged in some area and you’ll need a professional to clean and replace the fuse.
2) Defective Gas Valve: If you have a gas-powered dryer, chances are any problems may be caused by a defective gas valve. If your gas valve isn’t functioning, you’ll have no heat and will need a repair or replacement.
3) Igniter Issues: For gas-powered dryers, an essential part of generating heat is ignition. A defective igniter will leave you without heat, and will need to be replaced.
4) Heating Element Failure: The heating element is the source of the heat that dries your clothing. If your heating element has failed, you’ll need to get a professional to install a replacement.
5) Heating Element Assembly Failure: More severe than a heating element failure, it is possible that your lack of heat is caused by damage to the entire assembly. Your technician may need to replace the entire heating element housing to get your dryer running again.
6) Sensor Issues: In gas dryers, a heat sensor sets the igniter in motion. With a defective sensor, your igniter may never kick into effect.
7) Power Supply Issue: If your dryer is receiving an inadequate power supply, it will not be able to function fully, and will face damage over time. Be sure your dryer is receiving an adequate supply, and plugged in and grounded as recommended by the manufacturer.
8) Thermostat Failure: In most dryers, a thermostat is installed to ensure your dryer will not overheat. If the thermostat is malfunctioning, it may indicate an overheat and prevent your dryer from functioning.
9) Cycling Thermostat: The cycling thermostat controls the heat of your loads and ensures laundry is heated to the perfect temperature. If this thermostat fails, your dryer won’t be able to produce heat, or is in danger of overheating and causing a secondary problem.
10) Controls and Timers: The function of modern dryers are handled by a control board and timers. If any of these controls are not functioning, your dryer may be receiving incorrect input, and fail to function.
When it comes to dryer problems, there are a lot of reasons you might be facing issues. Some of these problems can be fixed at home through a round of troubleshooting, but others will need to have the appliance repair expert in San Diego County work on it.
