VC 2560 Blower

I just installed a used VC 2560, converted to propane, direct vent, with blower. I hooked up a thermostat today and the pilot stays lit and the main burner lights and secures as it should. My problem, however, is that the blower never turns on.

I have the thermostat hooked up to the top and bottom terminals on the pilot valve assembly itself. The three-way switch on the blower control is in T-stat mode. The Rheostat is set for roughly mid-range. The blower is plugged in. Any ideas on where to start? I'd like to get that blower running. It would throw the heat nicely.

Thanks for the quick reply. Yes, the rheostat clicks all the way counter-clockwise. I'll pull the blower and check the wiring next.

I pulled off the rear shroud and am giving the stove a good cleaning. There is a sign on he interior that says "WARNING: DO NOT attempt to re-install the pin into the safety switch. Altering or modifying this switch could cause an explosion or serious injury."

What is the safety switch? I found a cotter pin dangling from a piece of thin wire rope. These parts are not listed or mentioned in the manual.





Edit: I pulled the blower and got a lot of dirt out. I also put power directly to the motor leads and only got humming, no movement. The squirrel cage is very stiff to rotate, so I suspect the windings are shot.

Oh well, at least I got a good deal on the stove. Woodman's Forge is just up the road, so I'll see if they have a fan kit in stock.

Edit 2: The pin held back a micro switch. I put the pin back in and now the three position switch functions properly for on, off, and t-stat. The small wire rope goes up to a small port near the upper part of the furnace. I suspect that is so someone does not remove the hatch and bypass the direct vent on accident.
