Lennox blower stopped working
Sorry for the double post but I couldn't find a way to edit the first one or delete it.
Woke up nice and warm last night, upstairs ac had stopped working. Compressor outside is running, but no blower. Tried manually setting the fan from Auto to ON, nothing. Doesn't matter if I have it set to heat or AC. Using a Honeywell programmable thermostat, swapped the upstairs one with the downstairs one, no difference. (Checked the fuses at the main fuse box, all good.) I have a Lennox Value Series model 80UHG3-75A-3. I checked the voltage at what I believe is the transformer, its on the right in the attached picture, it read at 25v, also according the diag lights the circuit board reports everything is normal. So I assume the issue is the blower fan? I was able to spin it with no resistance. Anything else I can do to troubleshoot this?
Thanks,
