Why does my Reznor Furnace motor turn on and off?
If your Reznor Furnace motor turns on and off while operating, it could be due to: * The motor overload device cycling. Verify the motor load against the motor rating plate. If that's not the issue, replace the motor or overload device. * If it's a three-phase motor, it might be rotating in the opposite direction. Interchange two legs of the supply connections to correct this.
How to troubleshoot insufficient heat in Reznor Furnace?
If your Reznor Furnace isn't providing sufficient heat while operating, consider the following: 1. Dirty filters in the blower system. Clean or replace them. 2. Incorrect manifold pressure. Check the manifold pressure. 3. Limit control cycling on. Check the air throughput. 4. Improper thermostat location or adjustment. Refer to the thermostat manufacturer’s instructions. 5. Belt slipping on the blower. Adjust the belt tension. 6. Fan control improperly wired. Ensure the wiring connections are in accordance with the wiring diagram. 7. Defective fan control. Replace the fan control. 8. Blower set for too low a temperature rise. Decrease blower speed or increase static pressure.
How to fix a venter motor that won't start in Reznor Furnace?
If the venter motor in your Reznor Furnace won't start, here are some things to check: * **No power to furnace**: Turn ON the power and check the supply fuses or circuit breaker. * **No 24V power to venter relay**: Turn up the thermostat and check the control transformer output. * Check for loose or improper wire connections. * **Defective venter relay**: Replace the defective part. * **Defective motor or capacitor**: Replace the defective part.
What to do if pilot lights, but main valve won't open in Reznor RPB Furnace?
If the pilot light in your Reznor Furnace lights, but the main valve won't open, consider these potential causes: * The manual valve might not be open; ensure it is. * If 24V power is available at the valve connections and the valve remains closed, replace the valve. * Check and tighten all wiring connections. * Ensure that the flame sensor lead is not grounded and that insulation or ceramic is not cracked; replace as required. * Adjust gas pressure. * Replace sensor, if there is cracked ceramic at sensor. * If all checks listed in Spark Ignition System Maintenance section indicate no other cause, replace ignition controller (do not attempt to repair ignition controller, which has no field-replaceable parts). * Adjust pilot regulator due to poor microamp signal.
Why does the motor cut out on overload in Reznor Furnace?
If the motor in your Reznor Furnace cuts out on overload, consider the following: * Ensure that the motor pulley is properly adjusted. * Adjust dampers in the duct system to correct improper static pressure. * Check the power supply to address low voltage.
What to do if the motor will not run in Reznor RPB?
If the motor in your Reznor Furnace will not run, check the following: * Check the wiring and connections for any open circuits. * Replace the fan control if it's inoperative. * Ensure that the wiring connections are in accordance with the wiring diagram. * Replace the contactor if it's inoperative. * Replace the motor if it's defective.
What to do if the pilot will not light with venter operating in Reznor RPB Furnace?
If the pilot light on your Reznor Furnace is not lighting even when the venter is operating, there are several potential causes: * The manual valve might not be open; ensure it is. * There could be air in the gas line; bleed the gas line. * The pilot orifice may be dirty; remove it and clean it with compressed air or solvent. * The gas pressure could be too high or too low; adjust the gas pressure. * The pilot tubing might be kinked; replace the tubing. * The pilot valve may not be opening; if 24V power is available at the valve, replace it. * Loose wire connections can be a factor; ensure all wire connections are solid. * Transformer failure; ensure that 24V power is available. * Incorrect spark gap; maintain the spark gap at 7/64 inch. * Spark cable shorted to ground...
