I recently replaced my fan limit switch when I noticed that the blower fan would not turn on and the unit would shut off on high limit. There was no change when I put in the new switch. After about 5 minutes the blower fan turns on and shortly after the induction fan turns on and then the furnace ignites. What should I look at to find the root cause of the problem. Thanks in advance for your help.
This is the most informative step by step video on this subject. Just what I was looking for! Thanks
Glad it was helpful!
