Danson Acutron II no convection blower

[Tim_ martell]

I have a Canadian comfort pellet stove with the acutron II CB. I've read in threads that the convection fan should come on at startup but it does not. Nor will it come on after the proof of fire switch engages and the cb it's past it's startup mode and in full run mode. It will however run when the f140 switch closes(I jumped it). I measured the voltage to the fan without jumping the 140 switch and it says I have full line voltage 120v to the fan. Any ideas?

I'm not sure of the stove model number. Not much on it really but the wiring is the same as the scematic

Replace the 140 switch.Room fan comes on,after that switch closes,140 degrees.

I'm pretty sure that switch is working fine. It's normally open, closes at 140 but I can check it

Do you have line voltage on both sides of the motor? What is the voltage from one motor lead to the other?

With the motor unplugged, I have 120v measured across the two wires that connect to the motor

What does it measure with the motor connected? Various wiring methods can give misleading readings with the motor disconnected (no load on the circuit).
