Ok I know it sounds like a simple fix but this thing is eating my lunch!

Motor will not start....I have checked and the following and all have ohmed out good....

1. Non rest OL for the motor (thermal cutoff)
2. Operating thermostat
3. Hi limit Themro
4. Heater
5. Door switch
6. Ohmed motor windings (I even hard wired to start so I know it runs)
7. Timer motor runs I can see it rotating
8. Will not start in any cycle

... Motor will not start....

Does it try to start ?
Does it make any noise ?

Yes "little white thing"

Does it try to start ?
Does it make any noise ?


No start at all.....dead--no movement
No noise, when I the press start button while holding door switch I do hear the start engage

See if BK-BU closes on timer, also push to start switch - Or/Wh to BU should close when button pressed
T-W on timer must close as well.

Seems to me that T-W contact has fooled me before

OK gotta a question......why is the "T-W contact" there? What is its purpose?
When I bypassed it to eliminate the timer it seems to work in all cycles.......just would like to know why would they install a redundant switch inline w/the motor?

So they would have a market for all those cases of timers stored in the spare parts area.

Likely for added safety thereby breaking both sides of the line when in the off position.

Ok, sounds about right, but when the timer times out the motor stops and when I opened the door the motor stopped..........So I am going with
sell more timers in the spare parts bin.

When the timer cam has advanced to the off increment, both the neutral and the hot are disconnected at the timer - if only 1 side is, components can then remain live when a short/ground etc occurs
