Fan/limit rising with fire off
I have a 23 year old forced air unit. It short cycles at times. It also seems to do something quite strange. After the fan has cooled the heat exchanger and the fan shuts off the fan/limit dial will raise in temperture to 110 or 120 or more with the burner off. I have changed out the fan/limit with no change . How can the heat exchanger rise in temperture after it has cooled to 100 with no heat going to it? Thanks
