Motor
The most common problem you will have with a motor is the capacitor. When you turn the motor on and you hear it humming/struggling to turn, the capacitor is most likely bad. With a testing device, you can test the capacitor to see if it's good or bad. A 65 mf capacitor will cost you about $30.
Engineers often misdiagnose the problem and recommend replacing the motor not realizing that the capacitor or limit switches or loop detectors could be bad.
