Kenmore 70 series electric dryer...wont heat
« on: May 27, 2008, 08:50:39 PM »
Ok...so ya'll have helped me fix this dryer once before, well that worked GREAT! Now it won't heat nor will it shut off...before I couldn't get it to turn on now I can't get it to turns off. If I turn it on to dry(no matter what cycle) it will run "like normal"(without heating up) then when it gets towards the end of the cycle it just keeps going and going and going! Any ideas?! HELP?!?!

Model 110.64742400

If you're using the "Auto Dry Mode", it won't stop till they're dry.
 Won't happen if there's no heat.

Try it on "Timed Dry" to see if it stops at the end of the timed cycle.

How's the air-flow out the back of the dryer with the vent disconnected ?

You may have to do some tests with a meter...

It does it either way, timed or auto...I normally use timed and when you do that now it runs till you have about 2-5 minutes left and just stays there FOREVER...literally...it went for over 10 hours one day. I turned it on then left the house, returned like 10-11 hours later and it was still running. That time it did dry the clothes but they weren't warm when I pulled them out. So after that I started using the suto dry part. Which in the past I have had to run twice to dry a load, did the same thing ran till I shut it off. What do you mean air flow out the back?! I'll ask the man when he gets home to see :) We have a problem with our kitty ripping the lint hose thingy sometimes, but we fix it everytime...would that hinder the dryer from getting warm?!

If the Timer gets stuck when in the Timed Dry mode, then the Timer is bad or the Centrifugal Switch on the Drum Motor

The cause of "no heat" when the Timer is running, is another problem.

Are you talking about the vent hose ?

It should be rigid metal vent with maybe a small length of flexible metal vent - NO plastic.
And NO screws, foil tape only

Then what?! he said he is going to take off the whole back of the dryer so I figure while he has it off if there is anything else he can do I'd find out before he takes the back off and puts it back on

Now some continuity or voltage tests will have to be done using the wiring diagram.

check the thermal devices in diagram

# 1 Thermal Cutoff Fuse






# 34 Hi-Limit Thermostat

Ok the continuity on both is fine and the voltage at all points on both is 120...what does this mean?!

Continuity = good

120v to ground = can't tell because each side of the circuit is fed from a 120v line.

With the machine unplugged, disconnect one wire from either of those devices, then plug in the machine and turn it to dry, then measure each of those two wires to ground to see which side (wire color) isn't connected to a power source.

Ok so they did that...all together there are 4 wires, 2 on the fuse and 2 on the thermostat...they unplugged one of the fuse wires(top), when they tested the unplugger wire 120...when they tested the plugged in wire 0...then they plugged both in to the fuse. unplugged one from the thermostat, tested both wires and same result...now what?!
