Furnace Blower Motor and Voltage Issue
I have a 1994 Itasca Suncruiser with a Suburban SF42 furnace. My blower is not turning on in my furnace. I verified the motor is receiving power from the time delay switch, which I replaced recently. A couple months ago, I had to replace my sail switch. So, it is possible the things is crapping out piece by piece. I have two questions. First, is there something else I should check before replacing the motor. Second, my voltage reading bounces between 13.74 and 14 on shore power and when my battery bank is at 100%. The furnace says the optimal voltage is between 12 and 13.5. Is the higher voltage killing my equipment? If it is, can I install a voltage regulator on the hot wires to drop the voltage to the correct range? Thanks!
