I am pretty much limited to changing parts but I don’t know which ones. I called about a transformer but I can’t get it until Monday. The furnace will not do anything, I switched the thermostat but since it quit when we were gone something could have burnt out. I have had frost get on the air intake an the furnace would not light, the inducer was trying to pull air but since it was blocked with frost it couldn't, and the inducer motor would run until I cleared the frost. When we left for the funeral it was raining then it got really cold so without being at home I'm thinking that could have been the problem? I just feel better when I know what the problem is. I'm not too good at troubleshooting.

Thanks for your help, I will go at it again tomorrow but I think it's going to be more then I can fix this time.

When the motor went out last year, and I had to get a universal one until the guy had me hook up the right wires even though they were different color the furnace acted like it is now so it may be another motor. The replacement motor was not the same speed as the original, I think we had a three speed and the new replacement was a two speed but it worked when he had me to hook up the right wires.
