2 Easy Fixes For A Drum That Spins Without Heat
If the drum in your dryer is still spinning but not producing any heat, there could be a few different reasons the system isn't working. The two most common reasons are a bad fuse or a failed temperature switch.
#1 Blown Fuse
One of the most common reasons that your dryer is still spinning without producing any heat is because a fuse has gone bad within your dryer. To get to the fuse, you are going to need to pull your dryer away from the wall and remove the back panel. This will allow you to gain access to the thermal fuse. Unplug your dryer, then unplug the wires from each terminal. Check each fuse to see if it is broken. If you find a broken fuse, you are going to want to remove the fuse from the electrical panel in your dryer and find a replacement fuse. This is one of the most common reasons for a dryer spinning without producing heat.
#2 Damaged Temperature Switch
Second, the temperature switch may not be working correctly on your dryer. In order to test the temperature switch, you are going to need a Volt-Ohm meter to test the temperature switch.
You are going to need to remove the knob that covers up the temperature switch on the dryer's control panel. You are going to want to set the leads to the temperature switch and turn on the Volt-Ohm meter. The Volt-Ohm meter should be set to RX1. Take the leads and touch the terminal and look at the reading; the reading should either be infinity or zero. Then, turn the switch into the on-position, and touch the switch again with the leads on your Volt-Ohm meter.
This time, you should get the opposite reading than you got before. For example, if the reading before was zero, it should now be infinity. If the reading was infinity, it should now be zero.
If the reading does not switch from zero to infinity or from infinity to zero, that means that the switch is bad and needs to be switched out. You will need to disconnect the damaged part and replaced it.
If your dryer drum is running, but no heat is coming out, a blown fuse or a damaged temperature switch could be the issue. It could also be a bad thermostat, heating coil, or timer. If you can't diagnose the problem yourself, a professional repair person can figure out what is wrong and offer expert dryer or washer repair.
