Kenmore dryer 110 62812100 no heat after repair
« on: May 01, 2016, 11:20:20 AM »
My wife seems to be hard on our dryer. About once a year I have to replace the heating element on our old Kenmore 110 62812100

This time she said it got real hot then stopped running. I replaced the heating element/thermostat and still wouldn't start. I replaced the thermal fuse (I had like 10 of them lol) and then it started up fine. However, no heat so I swapped in the old heating element/thermostat still no heat.

Can someone tell me what I should be seeing voltage wise in the pic below on the terminals on the right? I'm thinking there's no power to it, does that power come from a switch on the motor?

The thermostat you show is the high limit.

There should be another one higher up on the heater. This is the thermal cutoff (fuse)

First I would check that the unit is getting 240 volts.

Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
Check the voltage at the wall receptacle
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.
Be careful as 240 volts is lethal !!!

If the power is OK, unplug the unit.

Check the operating thermostat on the blower, it should be 0 ohms.

Check the thermal cutoff on the heater, it should be 0 ohms.
Check the high limit on the heater it should be 0 ohms.

If the thermal cutoff is blown (open) replace both it and the high limit.

Do not use the old heater as it may be shorted to ground which can cause it to run unregulated (hot)

The way the heater thermostats work is that if for some reason the heater runs hot the high limit opens and closes to regulate the temperature.
But it's contacts are not that robust so after a while they often weld together the thermal cutoff then blows.

After the repair run the unit on a low heat setting to check it.
If it runs too hot then I would replace the operating thermostat on the blower.
I think you may have already done this.

I'm trying to follow along. Here's a pic higher up. So the thermal fuse at the right should be 0 ohms with the dryer unplugged?

After you figure out why you get no heat have you ever clean out the filter housing?

OK, I think I'm following along. The pic below is the thermal cutoff (fuse) that's in my previous picture. It should have continuity with the dryer unplugged from one terminal to the other, correct? (normally closed). Sitting here on the table, I get no continuity from from one terminal to the other so it is blown?

If correct, should I be able to connect the two wires together with a spade to temporarily determine if that is the problem? (bypass the fuse) I'd know in about 20 seconds or so wouldn't I?

if that hi limit fuse is blown. Clean your lint housing (where the screen sits) and your venting or replace it.

I ordered a couple of thermal fuses, should be a few days.

I will be checking the airflow paths to see if it died or was murdered lol.
