Model 970-C81062-00

Serial XD13107478

Built 8/01

 

Turns on, heats up, dries clothes -- but the timer doesn't advance no matter whether an automatic or timed cycle is selected. My guess is the timer motor's shot…yes?

 

Could do with a service manual for this one, too, please and thanks kindly.

Got it, thanks. In checking more carefully, I find I was wrong: it's only on the automatic cyclies that the timer doesn't advance. On a timed cycle it does advance. The manual you linked has flowcharts to cover this possibility, but I'm not certain whether the 970-C81062-00 does or doesn't have an electronic moisture sensor. Derp! I are all smart and stuff! Not only can I identify the moisture sensor strips below the air grate, but I can also read the front of the dryer where it says "Electronic Moisture Sensing"! aHyuck! Sheesh.

 

Guessing probably a dead moisture sensor; will put my DMM across it and see what I find.

I removed the moisture sensor, disconnected its two red wires, and measured the following:

 

Across the moisture sensor's terminals: Open

 

Across the moisture sensor's terminals with a wet rag placed on its two bars: 5 MΩ to 10 MΩ (depending on how wet the rag was)

 

Across the two red wires: 3 MΩ to 4 MΩ

 

The service manual's kind of vague in this area; what do these readings tell us?

 

(I also did clean a giant wodge of tightly compacted lint out from between the moisture sensor and the sheetmetal)

 

Thanks, all.

In Auto-Dry mode, the Timer Motor won't get power to advance, if the Dryness Board thinks the clothes are still wet.
Seems like a bad Board

Thanks. Looks like I got lucky this time -- with the lintbrick safely sequestered in the tank of my vacuum cleaner and the sensor reinstalled, the timer's now advanced properly through three actual, real loads of actual, real wet --> --> --> dry laundry in a row. A fluke? A short across the sensor due to a piece of tinsel or suchlike in the accumulated lintbrick? Divine intervention? Donno, but at least for the moment it's stopped me needing to buy any new parts, thus decreasing my contribution to keeping the economy rolling, which means it must be Obama's fault or something. ;-)

Also a good maintence act, is taking a green scrub pad to the surface of those sensor bars. They tend to get coated with fabric softener over time. When they be coated, they won't sense.
