WP12555902 – Genuine OEM Whirlpool Refrigerator Start Device

The WP12555902 is a Genuine OEM Whirlpool refrigerator compressor start device and overload relay assembly designed to help initiate compressor operation when cooling is required. Manufactured to Whirlpool’s original factory specifications, this critical refrigerator component ensures dependable compressor startup, protects against overload conditions, and helps maintain proper cooling performance.

Compatible with select Whirlpool, Maytag, KitchenAid, Amana, Jenn-Air, Kenmore, Roper, Admiral, and related refrigerator models, the WP12555902 commonly resolves refrigerator startup failures, compressor clicking sounds, and no-cooling issues caused by a defective relay overload assembly. Verified by Whirlpool, AMRE Supply, and Reliable Parts.

Available from Appliance Kingdom with fast Canada-wide shipping for homeowners, landlords, and appliance repair technicians.

What Does the WP12555902 Refrigerator Start Device Do?

The refrigerator start device is mounted directly to the compressor and supplies the electrical boost needed to start the compressor motor during each cooling cycle. It also contains overload protection that shuts the compressor down if unsafe operating conditions occur.

This component is essential for:

  • Proper compressor startup

  • Preventing compressor overheating

  • Protecting against electrical overload

  • Maintaining refrigerator and freezer cooling performance

  • Supporting long-term compressor life

A genuine OEM Whirlpool start device ensures correct voltage characteristics, reliable protection, and safe operation. Incorrect or low-quality replacement relays can lead to repeated compressor failure, poor cooling performance, or damage to the sealed system.

Common Symptoms Indicating Replacement

A failed refrigerator start device often causes compressor startup failure and noticeable cooling issues.

Common signs include:

  • Refrigerator not cooling

  • Freezer not freezing properly

  • Clicking sounds from the rear of the refrigerator

  • Compressor attempts to start but shuts off

  • Refrigerator warm inside

  • Compressor overheating

  • Intermittent cooling performance

  • Refrigerator repeatedly cycling without cooling

If your refrigerator clicks repeatedly but does not cool, replacing the WP12555902 start device often resolves the issue—provided the compressor itself is still functional. This is a commonly recommended first diagnostic repair for compressor startup failure.
