GE Refrigerator Compressor Start Relay & Overload Replacement

GE Refrigerator Compressor Start Relay & Overload Replacement — What This Part Does

The compressor start relay (often a PTC device) momentarily energizes the compressor’s start winding to kick it into motion, then drops out once the motor is running. The overload protector monitors current draw and temperature. If the compressor pulls too many amps or overheats, the overload opens the circuit to prevent damage. Both mount directly on the compressor terminals at the back of the fridge.

The relay fails when the PTC element burns out, develops high resistance, or cracks. The overload can stick open or trip prematurely from age or heat cycling. When either part goes bad, the compressor won’t start or will click and shut off immediately. Sometimes the real problem is a locked or failing compressor drawing excessive current, which trips a good overload. Always test the relay and check compressor behavior before ordering parts.

Signs It Needs Replacing

• Compressor clicks once or repeatedly but never runs You hear a click from the back every few seconds or minutes, but the compressor never stays on and the fridge doesn’t cool.
• Refrigerator suddenly stopped cooling The lights work and the fan may run, but there’s no hum from the compressor and food starts warming up.
• Relay or overload is visibly burned or cracked You pull the rear access panel and see charring, melted plastic, or cracks on the black relay assembly plugged into the compressor.
• Relay tests open or very high resistance With a multimeter, the PTC relay shows no continuity or reads well above the typical 3 to 12 ohms at room temperature.
• Compressor is warm but won’t start The compressor body feels warm to the touch but you never hear it run, suggesting the overload is cutting power before startup.
• Start relay pulls off easily or terminals are loose The relay assembly wiggles or slides off the compressor pins without resistance, indicating poor contact or damaged terminals.

How to Replace It

1. Unplug the refrigerator and move it away from the wall so you can access the rear lower panel.
2. Remove the compressor access cover by unscrewing the sheet-metal panel or unclipping the plastic guard at the back bottom of the unit.
3. Locate the black plastic relay and overload assembly plugged onto the side of the compressor (a cylindrical metal canister).
4. Pull the relay straight off the compressor terminals and disconnect any wire leads or capacitor wire if present (note their positions for reinstall).
5. Inspect the old relay for burn marks, cracks, or damaged pins, and test it with a multimeter if you want to confirm failure (expect roughly 3 to 12 ohms across the PTC relay terminals at room temperature).
6. If the relay tested bad or shows visible damage, push the new relay firmly onto the compressor pins until it seats fully and reattach any wire leads in the same configuration.
7. Reinstall the compressor access cover and secure all screws or clips.
8. Slide the refrigerator back into place, plug it in, and listen for the compressor to start and run continuously within a few minutes.
9. Monitor the fridge for the next hour to confirm the compressor stays running and the cabinet begins to cool down.

When to Call a Pro

If the new relay clicks and trips immediately, the compressor itself may be locked up or drawing excessive current due to internal failure. Compressor replacement or a full sealed-system repair requires refrigerant recovery, brazing, and EPA certification. Also call a tech if you see oil leaking from the compressor, smell burning insulation, or if the compressor is too hot to touch within seconds of plugging in. A pro can run a current clamp test and compare startup amps to the compressor nameplate to decide whether the relay or the compressor is the real problem.
