Compressor fails to start or runs only briefly before shutting off, causing fridge and freezer temps to rise.
Repeated clicking or humming every few minutes as the compressor attempts to start then trips on overload.
Overload protector repeatedly cuts power due to excessive current draw or high compressor temperature.
Fridge appears to have no cooling activity — fan may run but compressor never engages due to failed start device.
💡 Pro Tip: How to Diagnose a Failed Start Relay & Overload
Your part is likely the culprit if you notice any of the following:
⚠️ Refrigerator not cooling — compressor tries to start but shuts off after 1–2 seconds
⚠️ Loud clicking or humming sound from behind or beneath the fridge every few minutes
⚠️ Compressor is hot to the touch but fan runs normally
⚠️ Visible heat damage, cracking, or burnt odor near the start device on the compressor
🔍 Quick Test: Remove the relay assembly and shake it — if you hear a rattle, it is defective and needs replacement. You can also test resistance across the overload terminals; a healthy reading is approximately 5–6 ohms. If the relay is open or rattles, replace this assembly before condemning the compressor.
