How to Replace a Fridge Compressor Start Relay
Rapid clicking from the rear and a compressor that won't start typically points to a failed start relay or overload protector. Replacing the assembly often restores normal operation.
Get a Confirmed Fit spare part
At Spares2Repair, when a spare part is matched to your exact model number we call that Confirmed Fit. Because spare parts can vary across production runs, sizes, and revisions, Confirmed Fit is the safest route to reduce wrong-part orders and buy with more confidence.
Start with the search box whenever you have the full model number. Use Fixit Fox Finder if the rating plate is hard to read or you want guided help before ordering. Ordering by appearance alone is more likely to lead to the wrong part.

Before you order, use Confirmed Fit
For advice and repair topics like this one, the biggest buying mistake is ordering on appearance alone. Search by the exact model number wherever possible, because small appliance revisions can use different seals, filters, motors, pumps, lamps, shelves, or trims.

Steps
- Unplug the fridge and pull it away from the wall. Remove the rear cover.
- Locate the black compressor can and the relay box on its side.
- Disconnect the relay/overload; note pin layout (C, S, R terminals).
- Install the new module per instructions; ensure a snug fit.
- Refit cover; power on. The compressor should start smoothly.
When This Won't Help
If the new relay clicks off again or trips, the compressor may be seized or there may be a supply issue. Call a qualified engineer for sealed-system diagnosis.
FAQ
How do I know this repair is relevant to my appliance?
Rapid clicking from the rear and a compressor that won't start typically points to a failed start relay or overload protector. Replacing the assembly often restores normal operation.
Do I need the full model number before ordering the replacement part?
Use the full model number exactly as shown on the rating plate. When Spares2Repair matches that model to a compatible part we call it Confirmed Fit. Similar-looking parts can differ across revisions, production runs, and variants, so model matching is the safest route before ordering.
What should I check before stripping the appliance down?
Confirm the fault symptoms first, isolate the appliance safely, and make sure the replacement part is model-matched before taking the appliance apart any further.
