Question about Dryers
Had a load in the dryer yesterday and now its not heating. Starts rotates just no heat.
So, your clothes dryer won't produce heat. There are a number of
possibilities for this problem. The first thing we must determine is
the type of dryer we are servicing. There are only two types; Gas or
If your dryer is electric, meaning it uses electricity instead of flame to produce heat, step one is to verify that the breaker to the dryer's electrical circuit is fully on. Since electric dryers require 240 volts to run, their circuit is run through a dual breaker switch. Sometimes only one half of the breaker switch will be off or fail which will supply enough power to make your dryer tumble but not enough for it to produce heat. Pop the breaker to your dryer off and on again and then see if the dryer will now produce heat. If it does, then have the breaker replaced. If it doesn't, you can verify that the dryer outlet is fully powered by testing it with a volt meter, You can learn how to use a volt meter here. If the outlet is fully powered then the problem definitely rests within the dryer.
Let's next deal with the failure common to both types.
You will need a continuity tester for this process. Directions for how to use a continuity tester can be found here.
After you have removed the power from your dryer and shut off the gas, you will also need to access the internal workings of your dryer. Directions for achieving access, specific to your brand, can be found here.
Most dryers have a thermal fuse located in the exhaust path. Depending on your dryer, the fuse will be found toward the front or the rear of your unit. Generally, if there is a removable back on your dryer then that is where you will find the fuse.
The two most commons thermal fuses you might find are shown in Figure 1. They are each roughly 1" in size. You will notice that the contact points are easily spotted for a continuity test.
In older units and some electrically heated units you will find a series of thermal fuses, looking like small tin cans, at various points along the heater assembly. These will also need to be tested before you can rule out thermal fuses as your problem. If any of the thermal fuses fails the continuity test, then it needs to be replaced.
