I have a BDP579D rooftop unit. The blower keeps running after the burner shuts off. If I tap the Cam Stat S106 time delay relay,the blower shuts off. I replaced the time delay but I still have the same problem.

Hey, Did you change the entire cam stat or just the relay? I would change the entire part and make sure it is set around 100-120 degrees as a shut off temp. If the temp is set to low, the blower will turn due to external heat(attic, closet, sunlight etc...)John...austin,texas
