Hi Gene,

Thanks for the reply.

Here are the results:

I removed all the wires from the following 3 parts:
- 3399848: top part of thermal cut-off
- 3390291: bottom part of thermal cut-off, also ca is called thermostat, High Limit
- 3387134: thermostat, Internal Bias

The 3399848 did NOT have continuity on two terminals, it showed near infinity resistance. (BAD!?)
The 3390291 did have continuity on two terminals as it showed 0 resistance. (GOOD!?)
The 3387134 has two pairs of terminals, the outside-long pair of terminals does HAVE continuity as it showed 0 resistance (GOOD!?), the inner-short pair of terminals does NOT have continuity as it showed near infinity resistance (BAD!?)

I bought all three brand new parts yesterday, before connecting to wires, I measured all parts' continuity,
the 3399848 showed 0 resistance (GOOD!), the 3390291 also showed 0 resistance (GOOD!), the 3387134,
the outside-long pair of terminals showed 0 resistance (GOOD!), the inner-short pair of terminals, however, STILL showed near infinity resistance (NO continuity, NO GOOD !?, or this is supposed to be!?)

Anyway, I installed these three new parts in place, and finally I GOT HEAT!!! look like that the 3399848 (top part of thermal cut-off) was BAD !, I put a load of wet clothes in the dryer, it did dry the clothes,
HOWEVER, IT DID NOT STOP ! AND CONTINUOUSLY RUNNING !!! I CHECKED THE Automatic Cycle Knob did NOT move AT ALL !!! STILL POINTED AT THE BEGINNING OF POINT!

Any idea/clue what part is bad causing this problem ????

Thanks again,

Dennis
