I have a Whirlpool dryer model LE5800XMM1 that I've owned for about 13 years. It no longer heats up. About two years ago it wouldn't heat up, and it turned out to be the heating element. Replaced that and life was good. Now same problem. Only this time the element tests fine for continuity. The high limit thermostat also tests good for continuity. Dryer has plenty of voltage going to it, and the timer is working. Dryer will shut off when the time runs out. Anyone have any ideas I can try?

Pull off the cover that covers up the 3 pin terminal block where the cord is connected to. Check to see if any of the wires going to the terminal block are burnt. Then set your meter to check AC volts and "carefully" measure the voltage between the three terminals. You should get 240 between the outer two and 120 between the center and both of the outer ones. If you don’t then you could have a problem with the outlet in which you would need to call an electrician.

I have pretty much disassembled this dryer and that is the only fuse I can find. I tested it for continuity, but it has none. Could this be my culprit? Unfortunately it has no part number on it.

verruckt, If the thermal fuse (#8 on the break down diagram) is open - it has to be replaced. If the part you mentioned is not the thermal fuse then try to locate it on the break down diagram and post the reference number. - The part number for the thermal fuse is AP3133489 Here are the break down diagrams for the Whirlpool dryer Model LE5800XMW1Gene.

Actually what I 'thought' was the fuse, was #5 here Model LE5800XMW1At the parts store they told me it wasn't the fuse. So they sold me the one you suggested and went back home. However, I have tested my thermal fuse, and it was good. I also tested what appears to be three thermostats on the same housing as the thermal fuse, they all tested good for continuity. They look exactly like the high limit thermostat on my heat element housing.

I started over from the very beginning and followed everything, from power source to the heating element. This time, the hi limit thermostat tested bad. In the beginning, it tested good. I've replaced it before, so I know what it is and how to test it. One of the leads was loose, and a little burnt looking which i didnt see the first time. If you wiggled the lead, it would test good, if it was moved slightly it would test bad. So, i replaced it. Plugged in the dryer and started it up. It immediately threw the breaker. My breaker is a double, so it threw the whole thing.

Also disconnect the heating element,
Then check the resistance of the element, it should be
somewhere around 8-12 ohms.
Then check to make sure that there is “no continuity”
between ether terminal and case ground
If there is then the element is shorted.
