How to Test a Refrigerator Compressor Start Capacitor ?

How to Test a Refrigerator Compressor Start Capacitor ? Hermetically sealed compressors use motor Start Capacitor to help them develop the extra torque needed to start under load. Motor Start Capacitor  can fail for many reasons, with age and heat being the two biggest causes. The refrigerator will not start in either case. The thermostat closes and the hermetically sealed compressor/motor starts to hum loudly and continues to hum until the m...

How to Test Electric Motor Capacitors ?

How to Test Electric Motor Capacitors ? Step 1 Remove power from the electric motor. Locate the motor's starting capacitor. The capacitor should be in the vicinity of the motor itself, often mounted to the motor case. Step 2 Perform a general inspection of the starting capacitor. If the capacitor is leaking, it is considered bad and must be replaced. Make sure the wiring is correctly connected and there is no damage to the wiring. If damag...
