My older model GE DRyer sounded like it was wearing the glides down so I opened her up. I found the glides in poor shape- both worn through to the felt backer. While I had it open I figured I'd replace the belt and do a de-linting.

I found a pair of wires that had burned through- looks like they had been arcing awhile. I followed them back to the thermostat housing below the lint filter. When I opened the housing it was packed with lint around the t-stat. I figured I would replace this too since the wires had fried, I thought the switch was bad as well.

The parts counter guy said that there should be two in that housing on this model. I told her there were only provisions for one. I checked when I got back, there is only one t-stat there (one hole). There are no markings on the part so I am not sure what the part is. Any idea what I need here and why the wires were cooked?


ps. Does the orientation of the flange to sensor help identify the type of t-stat it is? I noticed that the t-stats on this linked page below each have a different flange rotation and they are each different.

Could not find a link for a VAL but here is one for a BBL
Model DDC0580BBL

There should be a second one but may be on the heater assembly itself.
See Item 507 in "Section 3"

The thermostat you show is the operating thermostat
I think the L145-15 means that it will open at 145 degrees and re-close at 130.
The other thermostat is a high limit thermostat.

Could be that the operating thermostat was shot never opened and you were running on the high limit, this would keep the heater on longer that it should and may have caused the wires to overheat.

Once a connector starts to go it generates heat which causes a poorer connection which generates more heat etc. etc. etc.

If the wires need repair make sure you get connectors which are rated for the required amperage. Also cut the wires back till you get good clean copper. Not a bad idea to clean the studs with some fine emery cloth.

Thanks den man,

How can you tell it is an operating thermostat? Does it have to do with the orientation of the mounting flange? OR is it because the label indicates 145-15? I used a stock photo- my thermostat looks kike this one; but the label is missing- no markings other than THERM-O-DISC and T.O.D.

The temperature on the label tells me it is an operating thermostat.

But if you compare the 2 thermostats. This one Item315 "Section 1" and the other one in my earlier post they are physically different.
