Maytag LDE712 Won't Stop

[xman1x]

I have an old school Maytag electric dryer, model number LDE712. When I plug it in, it starts and runs automatically. The only time it will turn off is when I open the door. Even when I turn the timer dial to an off position, it will not turn off. I have never seen anything like this before. Any help will be appreciated!

most likely a bad timer.

Well I ordered and installed the new timer and I have having the same issue. Could it be the start switch? Or something else? Looking like I am going to have to scrap it, which is a shame as it seems to still have life left with all of the other essential parts.

I'll bet you have a short to ground somewhere. First place I'd check would be the heating element. Use the wiring diagram to see what is the the circuit which could cause this. Start switch will be very easy to check with a simple ohmmeter.

This is a very different OLD control system on this one.   I can't remember working on this style in that old/newer vintage Maytag but in the very old Halo of Heat Maytag's they used a somewhat similar control system.

I couldn't find a wiring diagram to go by, If you have the wiring diagram in the console and can scan it and upload to an external site and make a link to it here I can take a look and help out.

I think you are going to find you either have a bad "Start/Control Switch" or the "Chime Solenoid".   I'm pretty sure on this unit when it gets to the OFF cycle it sends power to the Chime Solenoid to chime and let you know the load is done and it also RESETS the control switch to OFF.

Ohm the Chime Solenoid and make sure the coil isn't open - if open then bad coil - Activate coil plunger by hand and see if that turns it off.   Even if the coil is good try to activate the plunger by hand and it should reset the control switch to OFF and turn the dryer off until you push the start switch again.

I didn't look up the Chime Solenoid but did look up the Start/Control Switch which seems to be no longer available.

Evaappliance, that is another good possibility that the electronic dryness control board is bad.

This dryer may not have a timed dry cycle, only auto dry cycles - No picture of the console to see what the options are.

i believe you are right budget,  i didn't realize that it was that style at first.  i believe it is the same principal of operation as the electronic halo of heat dryer as you said earlier.  wish todays electronics were half as good as these !
