One of the most crucial components that keeps our refrigerators running efficiently is the thermostat. This unsung hero, found primarily in high-end manufacturers like KitchenAid, is essential to keeping your food fresh since it maintains the ideal temperature. This article will go into great length about your KitchenAid refrigerator’s thermostat, including how it operates, when to replace or fix it, and any red flags that suggest something may be wrong.

How Does a Thermostat Work?

Sustaining the Proper Temperature

Monitoring and regulating the inside temperature of the refrigerator is the thermostat’s primary duty.
It delivers signals to the compressor based on temperature, instructing it when to start or stop in order to maintain a consistent atmosphere.

Energy Efficiency

By ensuring the compressor only runs when necessary, the thermostat aids in energy conservation.
This not only extends the lifespan of the compressor but also reduces your energy bill.

Signs Your Thermostat Might Be Malfunctioning

It’s essential to recognize when your thermostat isn’t working correctly to prevent food spoilage or increased energy costs. Here are the common signs:

Inconsistent Temperatures

  • You might find certain areas of your refrigerator are colder or warmer than others.
  • You may notice your food freezing or becoming too warm.

Refrigerator Is Constantly Running

If your refrigerator is always running without taking breaks, the thermostat might be failing to signal the compressor to stop.

Refrigerator Doesn’t Start

In some cases, a malfunctioning thermostat might not signal the compressor to start, leaving your refrigerator warm.

How to Fix or Replace a Malfunctioning Thermostat

Testing the Thermostat

Manual Test

Turn the thermostat from the lowest setting to the highest setting. Listen for a click which indicates it’s working.

Multimeter Test

Disconnect the refrigerator and locate the thermostat. Using a multimeter, check for continuity. No continuity suggests the thermostat is faulty.

Replacing the Thermostat

Gather Necessary Tools

Screwdriver, new thermostat, and user manual.

Safety First

Always unplug the refrigerator before starting any repair.

Accessing and Replacing

Locate the thermostat, usually behind the temperature control panel. Remove screws and panels as needed. Replace the old thermostat with the new one.

Consult the User Manual

For model-specific guidance, always refer to your KitchenAid user manual.

TOP-5 F.A.Q.

How often should I replace my refrigerator’s thermostat?

It’s not about how often, but rather the signs of malfunction. Most thermostats can last many years without needing replacement.

Can a faulty thermostat lead to food spoilage?

Yes. If the thermostat doesn’t maintain the right temperature, food can spoil faster.

Is it expensive to replace a thermostat?

The cost varies. However, thermostats are generally affordable, and replacing them can save on future KitchenAid refrigerator repairs and energy costs.

Can I replace the thermostat myself?

Yes, with the right tools and guidance from your user manual. However, if unsure, it’s best to call a professional.

How do I know if my thermostat or compressor is the problem?

A faulty thermostat usually leads to inconsistent temperatures or the fridge running constantly. If the compressor is at fault, you might hear unusual noises or experience cooling inefficiencies even if the thermostat is working.
In conclusion, the thermostat plays a pivotal role in your KitchenAid refrigerator’s functionality. Regular checks and timely replacements can ensure your food remains fresh and your appliance runs efficiently.
