  If the venter motor on your power-vented Reznor Furnace won't start, it could be due to several reasons: * No power to the furnace: Turn the power on and check the supply fuses or circuit breaker. * No 24V power to the venter relay: Turn up the thermostat, check the control transformer output, and inspect for loose or improper wire connections. * A defective venter relay: Replace the relay. * A defective motor or capacitor: Replace the defective part.
