Understanding the Problem
What the starting relay is and why it matters: The starting relay (sometimes sold as a start device or start/overload kit) is attached to the compressor on most refrigerators. It gives the compressor the extra torque it needs to start. If the relay fails the compressor won't start even though power and the thermostat are working, so the fridge won't cool properly. Step‑by‑step diagnosis and repair (practical how‑to): 1) Confirm the symptom: If the fridge is warm, the compressor is quiet or only clicks, and the evaporator fan and condenser fan (if present) are running, suspect the start relay/overload or compressor itself. 2) Safety first: Unplug the refrigerator or switch off the dedicated breaker before doing any work. 3) Access the relay: Move the fridge away from the wall, remove the lower rear access panel (usually held by screws). The compressor is the black cylinder at the back bottom of the fridge; the start relay/overload is clipped to the compressor terminal block or in a small plastic housing nearby. 4) Visual and audible inspection: Remove the relay and overload assembly. Shake it gently — a worn relay may rattle. Look for burn marks, melted plastic, or a burnt smell. 5) Bench test (low‑tech): With the relay removed, try to start the compressor by briefly jumping the start winding (only if you are experienced). If the compressor runs when helped to start, the relay is bad. If the compressor hums but won’t run even with a start assist, the compressor may be seized (professional repair needed). 6) Multimeter checks: Use a multimeter to check continuity between the relay terminals per the manufacturer’s wiring diagram. Typical tests: continuity on the overload portion, and a change in resistance on the start device. Exact readings vary by design; no continuity or open circuit on the overload means replace the kit. 7) Replace the part: Obtain the correct start/overload kit for your model (see parts below). Install the new relay by seating it on the compressor terminals and clipping it or reinstalling its retaining hardware, then reattach any wiring in the same positions. 8) Power up and observe: Plug the fridge back in and listen. The compressor should start (you’ll hear it running) and the fridge should begin to cool within a few hours. If the compressor still only clicks or won’t run, the compressor or the start capacitor (if equipped) may be faulty — call a refrigeration technician. Additional notes for owners: Some modern Whirlpool units use electronic start devices or PTCRs; tests are the same general idea but the replacement part must match the model. If you’re unsure, use the fridge model number to order the exact OEM start/overload kit. Safety note: The compressor area carries mains voltage and refrigerant lines are nearby. If the compressor needs replacing or there are refrigerant issues, hire a certified appliance or refrigeration technician. Always disconnect power before touching components.
Common Symptoms
Fridge not cooling; compressor clicks but does not run; compressor silent while fans run; intermittent cooling that starts after tapping the relay.
Common Causes
- Failed start relay/start‑overload (wear, thermal damage)
- Seized or mechanically failed compressor
- Faulty start capacitor or electronic start device (on some models) or wiring/terminal corrosion

Helpful Repair Tip
If the compressor makes a single click when the unit first powers and then is silent, remove and shake the relay — a rattle or visible burn damage almost always means the relay/overload needs replacing.
Frequently Asked Questions
How much does replacing the starting relay cost?
Part cost for a start/overload kit typically runs from about $15 to $60 depending on OEM vs aftermarket and your model. If you hire a technician, labor will usually add $100–$250 depending on travel and local rates. If the compressor itself must be replaced, costs rise significantly and often exceed the value of the fridge.
Can I run the refrigerator with a bad start relay?
No. Running with a bad start relay will usually prevent the compressor from running, so the fridge will not cool. Repeated attempts to start can overheat the relay or damage the compressor. Replace the relay promptly or consult a professional.
