Title of Question:

Furnace Fan Keeps Coming On



 

Name: Philp  City: Orlando

Question: I have a Rheem furnace. The exhaust fan comes on, the gas and then the main fan. When the main fan shuts down, about 10-20 seconds later, it comes back on and stays on sometimes up to 1 hour, without the gas coming back on. What gives?
