Customer Questions and Answers for Run Capacitor by Whirlpool

4.89 (64)
By: Whirlpool
Part Number: OEM18030570
Manufacturer Part Number: WP65889-4

The Run Capacitor is an OEM part for Whirlpool refrigerators. It is responsible for helping the compressor motor start and run efficiently by providing an extra electrical boost. This component ensures that the refrigerator operates smoothly and maintains the correct temperature by stabilizing the compressor's performance.

Causes of a bad run capacitor can include electrical surges, age-related wear, or overheating. When the capacitor fails, the compressor may struggle to start or run continuously, leading to inefficient cooling or a non-functional refrigerator.

Symptoms of a bad run capacitor include:

  • The refrigerator not cooling properly
  • The compressor not starting or running intermittently
  • Unusual clicking noises from the refrigerator

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Answer

Hello John, without a model number, we are limited to some general checks. In normal run mode the evaporator fan, condenser fan, and compressor should be running. If you have a multimeter you can check for 120v starting at the compressor and condenser fan terminals. If they are all running that would indicate a sealed system leak. Also, your model came with a technical testing sheet, it is located under the top right side door hinge cover or under /behind the lower front grill, you can use it to run tests on the components from the control panel.
