  If the venter motor on your Reznor Blower isn't starting, here are a few things you can check: * First, make sure the power to the furnace is on and check the supply fuses or circuit breaker. * Next, verify that there is 24-volt power to the venter relay. Turn up the thermostat and check the control transformer output. Also, check for any loose or improper wire connections. * If power is available and the connections are good, the venter relay, motor, or capacitor might be defective and need replacement.

  If your Reznor Blower motor is turning on and off, it could be due to the motor overload device cycling. Verify the motor load against the motor rating plate. If necessary, replace the motor or overload device. Also, if you have a 3-phase motor, ensure it is rotating in the correct direction by interchanging two legs of the supply connections.
