I have an Englander pellet fireplace insert that was purchased at Home Depot in 2000 or 2001. It must have been sitting on the floor for a while, because it has two heat blower motors. I was told by Englander that pre-1996 models had 2 blowers. I do not have a model #. I think the circuit board has gone out on it. It has dials instead of a digital readout. How would I order this part?
