Check the Temperature Control Thermostat — Test Temperature Control Thermostat

Refrigerator Repair · Step 8 of 10
In this video
The temperature control thermostat is a key component responsible for regulating the operation of the compressor, evaporator fan motor, and condenser fan motor. A malfunctioning thermostat can lead to the refrigerator not maintaining the correct temperature, causing it to run warm. One method to check the thermostat is to rotate its dial from the lowest temperature setting to the highest. As you turn the dial, listen closely for an audible 'click,' which indicates the internal switch is engaging. If you do not hear a click, or if further testing with a multimeter reveals that the thermostat does not have continuity at all settings, it suggests the thermostat is faulty and requires replacement.
FAQs
What is the most critical safety precaution I must take before attempting any refrigerator repair?
Always unplug the refrigerator from its power source before starting any inspection or repair, even for simple tasks like cleaning condenser coils. This prevents serious electrical shock and ensures your safety throughout the process.
Is a multimeter truly necessary for basic refrigerator troubleshooting, or can I skip it to save on tools?
A multimeter is highly recommended and almost essential for accurately diagnosing electrical components like fan motors, thermostats, and start relays. It helps confirm if a part is faulty, preventing unnecessary purchases and ensuring you address the correct problem.
My refrigerator isn't cooling properly. What are some common DIY fixes for this, and what's their difficulty level?
Often, cooling issues are due to dirty condenser coils or a malfunctioning evaporator or condenser fan. Cleaning coils is an intermediate DIY task, crucial for efficiency. Testing and replacing a fan motor, also intermediate, requires careful handling of electrical connections.
The project suggests an estimated time of 6 hours. Does this include diagnosing the problem, or just the hands-on repair work?
The 6-hour estimate typically covers both diagnosing common issues and performing the subsequent repair. Be prepared to allocate sufficient time for initial checks, component testing, and potential trips for parts if replacements are needed.
