I have a furnace that when calling for heat the inducer motor starts to spin but shuts back off immediately. I have to turn the thermostat heat off and back on several times before everything works correctly and starts heating. I did the test on the circuit board module and the inducer motor turned on right away. As everything else came on correctly also. When I turned thermostat on and unit is calling for heat I checked for voltage at the inducer motor and got no voltage. Would this mean the motor is going bad? Even though during the board test it came on fine?
