How to Test a Dryer Motor
If your dryer has stopped working, or you suspect something might be wrong with it, you may be looking at a problem with the dryer motor. If this is the case, you may want to test it to see if it is working properly. Below you will find a simple guide to testing your dryer motor.
Step 1 - Turn off Power
The first thing you will want to do is disconnect the power supply from the dryer. This will be done either by unplugging the dryer if it is plugged in or turning off the circuit breaker switch that it is attached to.
Step 2 - Turn Dryer on Its Side
In order to access the motor, you will need to turn the dryer on its side.
Step 3 - Remove Belt
Once you have located the dryer motor, remove the rubber belt from the motor with your hands or with the assistance of a screwdriver.
Step 4 - Check for Obstructions in the Blower Fan
Look inside the housing for the blower fan. If there are any obvious obstructions, remove them.
Step 5 - Rotate Shaft of Motor
Next, manually rotate the shaft of the motor. If the shaft does not rotate, your motor is most likely bad and will need to be replaced. If you can rotate the shaft, plug the dryer back in and run the motor without the belt on. If the motor runs fine without the belt, you most likely have a problem somewhere else in the motor. If the motor does not run without the belt, you will need to replace the motor.
