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.
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.

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.

Go round back where the cord attaches and  remove that cover plate. Measure voltage there only, also check the wires there for loose connections. Remember, there must be 240 volts between L1 nd L2

I would check for voltage at the start switch with the dryer plugged in and the timer in the on position. If you read 110 or so volts it's probably the motor . If you dont it's probably the timer.

With the Timer set to Dry, and the Start Button at rest, there should be 120v on one side of the Start Button (tested to chassis, ground), then the Timer, both Thermal Fuses, the Motor, and the (internal) Motor Overload are connected together.

When you push the Start Button, that 120v should now be 0v (if the Door Switch is good).

OK, guys! Kudos to you all! Repair-man, I checked the voltage on the back panel as you suggested, and found the issue! It turns out the bakelite (or whatever the dark brown plastic is these days) on one of the sockets of the surface receptacle had broken, and allowed the prong of the plug to break contact, so there was no problem with the dryer at all!!

Replaced the receptacle and all is good! Wife is happy, and you know that when Momma is happy, it's all good!

Thanks again to all of you! I love this board!

It was strange - when I checked the voltage at the receptacle, it was OK. I guess I had stuck the probe from the meter in the receptacle just right, but when I plugged the dryer back into the receptacle, then checked the voltage at the back of the dryer, I had zero.

I guess I'm lucky we didn't have a fire - a little surprised the breaker didn't trip.

The voltage can be OK at the Outlet, but if there's a bad/loose connection at the Dryer Terminal Strip, the Dryer won't have the voltage, and neither will your meter if measuring there.

A bad/loose/open connection won't cause the breaker to trip
(it's not a short nor over-load).

A fire could be caused by the
heat of the bad connection, even with normal loads.

Along time ago in a galaxy far far away my very first dryer I uncrated out the box and installed the pigtail I stripped out the nut on one of the hot legs. I delivered the dryer without any problem. Later that day the old timer told me he had just come from replacing the terminal and pigtail from my fubu. Luckily for me I had other skills which impressed the boss. That day I repo'd a 90 days same as cash big shot school principle who had forgotten to "mail" the check.
