Fixed my bad board problem in 10 seconds...

While trying to quiet down the 17 year old room air fan on my St. Croix I noticed a snap disc disconnected inside the stove. I've had a problem with the stove not being able to shut down while still burning pellets... the switch would shut down the stove and I'd get smoke back into the room... just figured the board was bad.

Anywho... I plugged in the two wires into the snap disc and voila! the stove operates as it should!

Now back to that squealing motor... I'll get to it this weekend. Might have to buy a new one from Don....

 

Interesting! Which snap disc was it?

 

You know I don't know! I think it was the one that switches the combustion fan on and off but I'm not sure... I was just happy to get it working. I'll do more exploring when I get back home this weekend.

 

That makes sense - if the switch was disconnected, the control would think the stove is cool and stop the fans. What I don't get is why you didn't get a shutdown due to not sensing a fire's heat...maybe your board is not quite right in the head...?

 

squealing motor bushings are prob screwed,dont understand rest of post?sorry

 

If I shut down the stove when it was 'on' it would also shut down the fans and I'd get smoke back... it should wait until the fire was out to shut down the fans.... which it is now doing again.

 

Many stoves place a snap disc in the circuit that controls the draft fan and or all the fans and when the snap disc is above a certain temp it bypasses the power switch and keeps the power on until the stove cools.
Turning off the switch stops the fuel feed only.

Whitfield did that on some models.

I normally switch the feed motor power off and let everything else run to cool the stove off gently and then kill the power after the stove is cool.

 

That's how this stove is.... again. Didn't do that for two seasons... I think I blew it off the last time I cleaned it using my air hose..
