Whirlpool Duet Dryer No Heat

[dec]

I have a Whirlpool Duet dryer that is producing no heat but is working otherwise fine. It stopped producing heat last week when my wife put in a load of wet towels. Trying to troubleshoot this and repair myself and looking for some help.

I went into diagnostic mode (more time-less time-more time-less time) and it displayed 88, hit start and it showed a 6. I also flipped the breaker on and off about 5 times and tried unplugging and plugging it back in the dryer.

I borrowed a multimeter and disconnected the dryer from the wall. Measuring the thermal fuse after disconnecting the wires it displayed 0.

According to a tech sheet in my dryer I found I tried the heater test. It says to measure from the red wire of the thermal cut off to one of the red wires of the heater. I did this with and without the wires connected and both times I got no reading on the multimeter.

I then tried to measure each of the three different parts there isolated. I disconnected both leads from each  and the heater element gave a reading of 9.8. The high limit thermostat displayed a 0. And the thermal cut off got no reading.

Is the problem a faulty thermal cut off?

And the thermal cut off got no reading.

The thermo cut off with no reading is bad.

Could you post the model number for us?

Replace the thermo fuse, part # 3392519 and let us know how it works.

The fuse? I'm slightly confused. When I measured the fuse I got a reading of 0 which I thought meant the fuse was good.

Part / Mulitmeter Reading
termal fuse - 0
thermistor - 12.8
heater element - 9.8
high limit thermostat - 0
thermal cut-off - no reading

Sorry for the mix up, you are correct.

thermal cut-off - no reading

The one with no reading is bad, also check your dryer duct to make sure it's clear of lint build up.

What is the part number of the thermal cut-off in the GEW9200LW1 Diagram that you have no reading on?

First thing I checked was the airflow out the back which felt pretty good. And the hose from it is pretty new, I installed and wired up a metal hosing to the outside about 6 months ago, I checked the outside and the flow there is good with the hose attached.

I'm unable to see the part number on the thermal cut-off because it's slightly hard to reach. I need to return the multimeter I borrowed but some time tonight I'll remove the cut-off and see what the part number is on it.

Finally got the thermal cut-off out and the numbers on it are 8318314 and just below that 8(or B)2 352F 7313

8318314 is the factory part number.
