  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.

Why is my Reznor SCE 225 motor turning on and off?

  Pamela MuellerAug 9, 2025
  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.

  If the pilot light is on but the main valve of your Reznor Blower won't open, try the following: * Ensure the manual valve is open. * Check for defective valve. If 24-volt power is measured at the valve connections and valve remains closed, replace the valve. * Inspect and tighten all wiring connections. * Make sure the flame sensor lead is not grounded and that the insulation or ceramic is not cracked; replace as required. * If all checks indicate no other cause, replace the ignition controller.

  Joy HouseAug 27, 2025
  If your Reznor Blower isn't providing sufficient heat, consider the following: * Dirty filters in the blower system can restrict airflow, so clean or replace them. * Limit control cycling can also affect heating performance, so check the air throughput. * Ensure that wiring connections are in accordance with the wiring diagram. * The fan control could be defective and require replacement. * If the blower is set for too low a temperature rise, decrease the blower speed or increase static pressure.
