56428012 – Genuine OEM Whirlpool Refrigerator Temperature Control Thermostat

The 56428012 – Genuine OEM Whirlpool Refrigerator Temperature Control Thermostat is a precision-engineered refrigeration control component designed to regulate internal fridge temperature by controlling compressor cycling. This is a Genuine OEM thermostat used in compatible Whirlpool refrigerator systems and cross-compatible models across several Whirlpool-family brands.

Available through Appliance Kingdom (Edmonton, AB, Canada), this part ships Canada-wide with fast delivery, making it a reliable solution for restoring accurate temperature control in residential refrigerators.

This thermostat is commonly used to resolve issues such as inconsistent cooling, over-freezing, or failure to maintain set temperature levels inside Whirlpool refrigerators.

Function & Importance of the Thermostat

The temperature control thermostat is the decision-making component of the refrigerator’s cooling system.

It works by:

• Sensing internal refrigerator temperature

• Turning the compressor ON when cooling is needed

• Turning the compressor OFF when the set temperature is reached

• Maintaining stable and safe food storage conditions

Because refrigeration systems depend on precise cycling, OEM-grade calibration is essential. Incorrect or low-quality thermostats can cause:

• Overcooling (freezing fresh food)

• Under-cooling (spoiled food)

• Compressor overworking and premature failure

A properly functioning thermostat ensures:

• Energy efficiency

• Stable internal temperatures

• Reduced strain on compressor and sealed system

Common Symptoms of a Failing Thermostat

A failing or inaccurate Whirlpool refrigerator temperature control thermostat (56428012) may cause:

• Refrigerator freezing food in fresh food compartment

• Refrigerator not cooling enough or inconsistent cooling

• Compressor running continuously without shutting off

• Refrigerator cycling too frequently

• Temperature fluctuations (too cold or too warm)

• Spoiled food due to unstable internal temperature

• Refrigerator unable to maintain set temperature

Will replacing this part fix the issue?

If your refrigerator is:

• Over-freezing food, or

• Not maintaining consistent cooling despite normal compressor operation

Then replacing the thermostat is often a high-probability corrective repair, especially when wiring and compressor components are functioning correctly.
