kudos:1 | Dryer-high limit thermostat or thermal fuse ? I just replaced the heating element and high limit thermostat (they came as a "kit") in our Admiral/Maytag ADE7000AYW clothes dryer. It had stopped getting hot and after replacement, it was fine .... for about an hour. Before, it would run, but not generate heat. Now, it does nothing. No light when you open the door, doesn't spin, anything. I have reset the circuit breaker it's on. Still nothing.
Reading other threads about similar issues here, people mentioned a thermal fuse frequently. Is the high limit thermostat the same thing ? I can see just about all of the electrical in and around the heating element, specifically from the connection terminal for the dryer cord to the heating element and see nothing additional. It wouldn't be in the control panel area or near the motor, would it ?
I do have a multimeter and get continuity between the thermostat, but very low, like 0.6. On the old thermostat, I get 16, if I remember right. Between legs on the element, I get a lot higher reading, in the teens, as I recall. What should I be seeing ? |

kudos:1 | I'd expect to see around 12 ohms for the element. |

Turns out there is a thermal fuse. I was looking at a parts breakdown online and didn't scroll down far enough.... Of course, no one stocks it except for the appliance parts stores, which are M-F and Sat morning operations only.... :(
I get NO continuity through it.
Let me check things again:
Old element: 11.5
Old themostat: 26
New element: 11.5
New thermostat: 0.6
Now I feel stupid that the element may be fine after all... It can't be returned so I might put the old back in if the thermal fuse solves the problem and keep the "new" element as it will surely fail eventually. |

kudos:1 | If the reading on the new thermostat is truly .6 ohms it is toast.
There are some reasons why an Ohmmeter will read incorrectly on a switch, however. The low voltage of the ohmmeter will not reliably punch through the oxide film on the contacts |

kudos:1 | Old one reads (starts out high and goes down) and reads around 26-27.
Did I damage it, most likely ? Even if I didn't, there's no returns on these parts (electrical ?), so it doesn't matter much... |

Actually, the old tstat is bad. A tstat is just a switch, and should not have any resistance when calling for heat. When its calling for heat it should be 0 ohms, and not calling for heat, at least 10,000ohms. 26 ohms on the old stat means its bad.
those readings on the element look good.
