Maytag electric clothes dryer
model DE710, series 01, (120/240V 3wire 60Hz 5600W)
Purchased around 1980
This is the almost 30 year year old electric clothes dryer from this previous post:http://www.handymanwire.com/ubbthreads/showflat.php?Cat=0&Board=UBB5&Number=757111
Some time ago noticed an intermittent problem where the dryer heater elements sometimes stayed on after a load of clothes finished drying. I would discover it was hot many many hours after the load ended and pull the plug to disconnect it from the power. If I later plugged it back in (after it cooled down) it would seem to work OK again. I'm pretty sure it also took longer to dry a load than it used to.
Any ideas what caused this?
Now it has finally changed to where the heater elements NEVER get hot. Except for not getting hot the dryer seems to run as it normally should.
I can follow electrical schematics and wiring diagrams (conveniently glued to to the inside of the dryer) and am pretty good at figuring things out but I have no experience with dryers beyond my previous post.
Hopefully it won't be too difficult to find where it loses power. According to the schematic there are a bunch of thermostats and switches in the path from L1 through the heater coil to L2 (The power cord is the old three wire style with L1, L2, and N).
