Hi, I have a Rheem RGDD-06NC-ER gas furnace. It turned on one morning and would not shut off via the thermostat. We had to shut the power off to the unit to get it to finally turn off. I replaced the thermostat ( a simple 2 wire unit ). I turned the furnace on, and it turned on and heated. I then turned the furnace off using the new thermostat which has an "off" position. The furnace then turned off. We turned the furnace on again and let it heat the house, but the furnace would again not turn off! Even moving the thermostat to the "off" position would not turn off the furnace, so we again had to turn the electricity off to the furnace to get it to shut down. This unit uses a Robershaw 780-715U ignition module. Is the relay and all other controls built into this module, and if so I'm guessing replacing this unit will solve my issue of the the furnace not wanting to turn off? Any help or direction will be appreciated![h1][/h1]

Replaced furnace/ac in 2014~ This year, furnace runs sometimes. Other times we have to trek outside, throw the breaker, take the side panel out and manually move the fan blades. When breaker is on again, works fine. Until it stops again. Armature flat spot? New fan motor? IDK! EDIT: The fan in question is maybe an evacuator fan? 5" diameter or so, maybe smaller. The hubbs and I are agreeing to disagree (I am right, tho) Is there such a thing? Sits right up against the outside, next to the flames. It is def not big enough to be the blower motor fan.
