The best refrigerator start relay matches your compressor’s part number and helps it start each cycle. A failed relay often shows up as a clicking sound every few minutes with a warm fridge, and it is one of the cheapest fixes for that symptom.
We compared start relays and relay kits on Amazon on part numbers, what is included and owner feedback.

How We Chose the Best Refrigerator Start Relay
To choose the best refrigerator start relay, we compared replacement refrigerator parts sold on Amazon in the U.S., including genuine OEM parts and aftermarket copies. We checked part numbers and cross-reference numbers, listed fit, dimensions, voltage and what comes in the box, and read owner reviews for recurring problems such as wrong fit, noisy motors, leaks, cracked plastic and short life. Because the right part depends on your exact model number, every pick below lists the numbers it replaces, and our guide explains how to confirm the fit before you order.
We checked efficiency claims against ENERGY STAR refrigerator guidance and food-safety temperatures against the FDA’s food storage advice (40°F or colder in the fridge, 0°F in the freezer). Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
How to Choose the Best Refrigerator Start Relay
Symptoms
Clicking every few minutes with a warm fridge often means a relay or compressor problem.
Match the type
PTC relays come in 1-pin and 3-pin versions.
Relay and overload
Many kits include both.
When it is the compressor
If a new relay does not help, call a technician.
Find your model number before you shop
Every refrigerator has a model and serial number label. Look on the inside wall of the fresh food section, on the ceiling, behind the crisper drawers, or on the door frame. Write down the full number including any suffix letters, because small changes in the suffix can mean a different part. Enter that number on the manufacturer’s parts site or a parts retailer to see the exact diagram and part numbers.
OEM vs aftermarket parts
Genuine OEM parts are made or approved by the refrigerator brand and match the original fit exactly, but they usually cost more. Aftermarket parts copy the OEM design and list the OEM numbers they replace. Many work well, especially simple parts like bins, bulbs and shelves. For electrical parts such as relays, valves and fan motors, read the listing’s compatibility notes carefully and keep the packaging until you confirm the fit.
Using cross-reference numbers
Manufacturers often replace a part number with a newer one, so one part can have several valid numbers. Listings show these as replaces or cross-reference numbers. If your old part shows a number that appears in the listing’s list, it is likely the same part. If it does not, check the brand’s parts diagram for your model before ordering.
Tips for a Smooth Refrigerator Repair
- Unplug first. Safety.
- Photograph connections. Easy rewiring.
- Shake the old relay. A rattle often means failure.
- Keep the old part. Until the new one works.
