Dryer runs and then shuts off. While it runs it is heating and drying fine. It will turn back on after about 15 minutes. What parts can I throw at it?
You will want to check the venting of the unit to make sure that the vent is not clogged which could cause a overheating issue. Also check the blower wheel to make sure that there is nothing in it which would cause a drag on the motor and check the rollers to make sure that they are not dragging which would cause the motor to overheat and trip out on overload.
I recently replaced a bad thermal cutoff because our element was not heating at all. I also vacuumed out the entire machine. Once I installed the new thermal cutoff, it seemed to be working great. However, about two weeks later the new thermal cutoff went bad too. What could be causing them to fail?
I have tested the cycle thermostat and it has continuity at room temp. I don't have a way to accurately measure the temperature, but when I put it on a skillet on my electric stove it does click and lose continuity once it's heated up, but (like I said) I don't know exactly at what temperature it switches off.
Answer Hello Michael,
The thermal fuse is just that. Thermal. This means that higher than normal temperatures is the only thing that opens the thermal fuse. In light of this information you can see why the first suspect is always the homes exhaust duct. If it is crimped, clogged, or excessively long, it will cause this problem. If flexible ducting is used behind the unit and the unit gets slid back against the wall, crimping the duct, this will cause it. The only other things that can cause it is if the cycling thermostat is stuck closed and the heating element is energized too long producing higher than normal operating temperatures, or if there are seals missing in the dryer, allowing the heated air to get back into the cabinet where room temperature air should be drawn in to aid in the cooling of the internal components.
My dryer stopped heating. Most say the thermal fuse is bad. How do you get to it ? The back of my dryer does not seem to come off.It's an older model, serial No. MP1303899 If this helps.
Answer Chuck, the heater element 3392537 and hi limit switch and thermal fuse 279769 are located on the base of the dryer, on the right hand side. You'll need to remove power to the dryer, open and remove the lower front access panel, and all the components will be in arms reach. Remove a couple of 1/4 inch hex head screws, label and disconnect the wires and slide the complete assembly out and test the switches and heater with a meter.
