White IrisesHere are some emergency repair methods for furnace inductivity blowers: – Check the power supply: – Reset the circuit breaker or replace the fuse: Check the furnace breaker box to see if the breaker for the furnace has tripped. If so, flip the switch back to the “on” position to reset it. If the furnace uses fuses instead of breakers, check if the fuse for the furnace circuit is blown and replace it with a fuse of the same amperage rating. Repeated tripping of the breaker or blowing of the fuse may indicate a more serious electrical problem, and professional help is needed. –
Examine the wiring: Disconnect all wires from the furnace fan and inducer motor, and check for voltage at each wire connection with a voltmeter. If there is no voltage at any connection, the problem lies in the wiring or power supply. Check for continuity between each wire and its corresponding terminal on the furnace fan and inducer motor. If continuity exists between terminals, replace defective components in the wiring or power supply.
Inspect the blower motor: – Check the motor bearings: If the inducer motor is hot but not turning, it usually indicates a failure of the bearings in the inducer motor. In this case, the inducer assembly needs to be replaced. Although temporarily getting the unit to run by oiling the bearings is possible, it will stop working again in a few hours or days.

Check the motor blade: Locate the blower motor, which is usually a cylindrical component with a fan blade attached. Try to spin the blower motor blade by hand. If it spins freely, it’s a good sign. If the blade is seized or difficult to turn, it could be due to a bearing issue or other problems with the motor, and further inspection or repair is required. –
Clean or replace the air filter: A clogged air filter can restrict airflow to the furnace, increasing the strain on the blower motor and potentially causing it to overheat and fail. Replace the air filter with a clean one of the correct size for your furnace, and make sure the airflow arrows are pointing in the right direction. –
Check the limit switch: The limit switch is a safety device that prevents the blower motor from turning on if the furnace gets too hot. Consult the furnace manual to locate the limit switch, usually near the heat exchanger. Visually inspect it for damage. Some limit switches have a reset button that can be pressed to see if it resets the switch. If unsure about the limit switch or its functionality, it’s best to call a professional. –
Remove obstructions: If there is noise coming from the inducer, it could be due to an obstruction. Birds and mice may crawl into the vent pipe and get caught in the blades, or the blower wheel may be falling apart. Remove the venting at the inducer to check for and remove any obstructions. If the blower wheel is damaged, it’s best to replace the entire inducer assembly.
