Hello,
I have an old GE furnace, from the 1960's I believe. Today the blower stopped working. I pulled the blower unit out and found the bearings destroyed on one side. I had no luck finding new bearings. So as a last resort a friend had an old furnace he had repalced with a blower motor that was working fine. I got it retrofitted in the furnace, however the old blower only had 2 wires going to the motor, the new motor has 5. I hooked up the white and black and it seemed to work fine initially. But sometimes the blower will begin to start and then stop. I assume there is more to the wiring than meets the eye. The new motor has white, black, red, blue and brown. I understand that the black, red and blue are for different speeds, but do I need to have the brown wire in the circuit somehow? If I hook the black, red or blue and the white to AC direct the blower works fine. Just seems to have problems starting in the furnace circuitry.
I realize this cannot be a permanent solution I just need to get through the Holidays and then we are looking for a new furnace.
Any help would be appreciated
Thanks
