Replace Compressor Relay and Overload Protector — Check Start Relay and Overload Protector
Part of project
Refrigerator Repair · Step 7 of 10
In this video
If the refrigerator's internal light turns on but the compressor does not produce any sound (indicating it's not starting), the problem likely lies with the compressor's relay and overload protector. Locate these components at the back of the refrigerator, usually attached to the compressor. Take a clear photograph of how the wires are connected to the relay and overload protector before carefully disconnecting them. These parts can be purchased online (e.g., from Amazon). Note that relays come in various pin configurations (2-pin, 3-pin, 4-pin), so ensure you order the correct type for your refrigerator. Once the new parts are acquired, re-attach them to the compressor, making sure to follow the connection pattern captured in your photo. After replacement, plug the refrigerator back in and check if the compressor starts.
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.
