Is that the one on the right side of the heating coil? If so, it has continuity, and there appears to be another thermal switch on the side of the heating coil (just like the one on the front of the blower cover) , and continuity on it is OK, too.

He got a reading of "10". It's bad

10 what ohms, kilo-ohms? Big difference, electronics 101 says to test the resistance of a component it must be out of circuit.

Maybe the timer or a bad wire in the circuit.

I started thinking timer, too. Any way to check anything on it?

But the dryer isn't working on ANY cycle, regular or permanent press or anything. Would the timer cause that? When the washing machine timer went bad, it would work on some cycles, but not others.

It's a Switch or Fuse, 10 ohms OR 10 kilo-ohms. It's more than it should be (less than 1 OHMS) It's bad. (If his meter is working)

Did you take at least one wire off both  fuses and check for continuity? One is on the heater element and the other one is on the blower housing. They both look the same but are different.

Hi limit thermostat shuts everything down try that.
No, it doesn't. Check both of the Thermal Fuses.
They're both white, but different.
One is on the Blower Housing, the other one is on the Heater Enlclosure.
No need to remove wires to test continuity of Switches and Fuses.

OK, looks like several responses, so let me tell you what I've checked. Once one of you mentioned checking the device and not the wiring, I made sure I pulled at least one wire off before checking anything for continuity. The 2 white thermal switches (one on the heater and one on the blower) are both good. The thermostat on the oppposite side of the heating coil from the white thermal switch checks OK. Based on what I read in the service manual, I checked what I THINK is the 160 degree thermostat on the front of the blower next to the thermal switch. It has 4 wires, black white, purple and blue. I checked continuity across the black/purple (per page 3-21), and did NOT show continuity, so I thought that was the issue. However, the guy at the parts counter says that this part would not keep the drying from starting at all, it would only keep it from getting hot if it was bad.

So, that's where I am now.

As far as a tech sheet, if you mean the wiring schematic, I found that taped inside the control panel, but am not savvy enough to know what any of that is telling me.

Check the Start Switch and the Door Switch

Continuity on door switch and start switch good when pressed.

That 4 wire thermostat is what you call a bias heater type. The 2 small legs do not read continuity unless you have a very good simpson meter that is sensitive. The way that dude works is it has a small heater coil in it and it heats up the thermostat where it will shut down faster on perma press and knit cycle. Looks like you is down to the motor and the timer.

That makes sense to me, either motor or timer. Is there a way to check either, or am I at the point where I call a serviceman?

I appreciate your comments about this old Maytag being as good as they get. It has survived 2 household moves, and has been pretty bullet-proof for all these years. Only routine stuff like a belt, and a tub bearing, and I think a new heater coil a few years ago.
