How do I turn off the inducer motor on my gas furnace
I have a similar issue Westinghouse dual pack on roof. Model is on another post of mine. Last summer we removed the variable speed motor. Added control relay and delay timer. All was well. Until winter. New problem that I thought was the control board. Replaced it and the prob still there. Most of the time after the stat shuts off . The blower turns off. And the inducer motor keeps running. I did some more testing. We have new control wire tied in to W on thermostat. Once when inducer was on and unit was off I pulled white wire , no change. When I removed the new wire we added for new control relay the inducer motor went off. I reconected it and it was fine til next cycle. Any ideas. I will take any input.
