Howdy! Our blower motor went out a couple of days ago. It was an old af 2 speeder. I replaced it with a 4speed and hooked the wires the same as the previous one. When the tstat sets the Fan to ON it kicks on no problem. When I set it to heat, the flame comes on but the blower motor never comes on. I've tried the same with the AC. The AC unit isn't kicking on nor is the fan.
When I replaced the blower motor I did have to unhook the thermostat wires for the AC unit. I hooked them back up the same way as before though... so I'm not really sure where I'm at now. I assume its something to do w/the tstat but... yea, 0 ideas.
The furnace is Rheem: Crition II Gas Furnace. I'm including any photos that might be useful. I tried doing a video but its way too large of a file to upload.
Edit: When the furnace is turned on and the flames are going I THINK I hear a 'click' like it's calling for the blower motor? I'm not sure that should have a clicking sound or if that's even what I'm hearing correctly. Disregard if this sounds like bad information.
Edit 2: The way I knew it was our blower motor is it started smoking. When I took it to Johnstone he said yep, it's toast. It did have some scorch marks that I found on it later where I'm assuming it sparked on itself. Could that have messed something up on the control board?
- New motor
- Old motor
- Tstat wiring pre-unhooking (red on the right and white on the left are all that got unhooked)
- Tstat after I hooked the wires back in.
- Wiring schematic (not sure if this is helpful)
