Step 1
Fix the blower motor on a furnace by first disconnecting the power to the furnace. Usually a furnace has a switch to turn the furnace on and off. Flip the switch in the off position. Turn the thermostat up to approximately 90 degrees to make the furnace turn on. If it doesn't turn on, the furnace isn't getting power, and it's safe to work on the blower motor. If the furnace does not have a switch, then trip the circuit breaker to the furnace, and turn the thermostat up high. If it doesn't kick in again, you can work on the furnace safely.

Step 2
Diagnose problems with car motors such as stalling, difficulty starting or not starting at all by first looking under the hood. Stalling could be a sign of the car needing a tune up, possessing worn spark plugs or a faulty starter. Work safely with car motors by first making sure the hood stays up. Some model cars have hinges on the hoods while others have rods that slide into place as the hood is opened. Use the proper tools to repair car motors. Don't improvise by using other tools as substitutes for the correct tool. Make sure nothing you are wearing like jewelry or clothing can hang down into the car motor. There are several parts depending on the car where jewelry and clothing can get snagged causing injury to yourself and possibly the car parts. If working under the car, make sure the car is securely hoisted and does not move. Use either an electrical hoist or the proper size portable ramps to safely lift the car up into position to repair it from underneath.

Step 3
Repair a rotary motor on a lawnmower safely by first disconnecting the spark plug cable. Use a piece of board to wedge the blade from turning while loosening it. Use safety gloves to remove the blade, and then mark the side of the blade that faces down. Check the blade for sharpness and balance. Then examine the hole where the blade is attached to make sure threads are not worn. Reassemble the blade, and then connect the spark plug cable.

Step 4
Repair washing machine motors safely by first unplugging the washer from the outlet. Check the outlet by plugging in a lamp to test the washer is getting power. If the drum doesn't rotate, check under the washer for any leaks or rusty stain. This indicates possible bad bearings in the motor.

Step 5
Check the tag on the appliance and consult the owner's manual to repair the motor safely. There are two types of electric motors AC (alternating current) and DC (direct current). Most small home appliances use AC.
