GE Refrigerator Error Code 0500

Code 0500 means the main control board has detected a short circuit in its relay driver circuit. The relay driver is the section of the board that switches power to components like the compressor and fans. This fault tells you either the board itself has failed internally, or something connected to its output, such as a fan motor or wiring harness, is shorting the circuit.

Start by unplugging the refrigerator for five minutes to see if the code clears, though a true relay driver short will typically return. Next, visually inspect the wiring harnesses and connectors for damage, and disconnect load components like fan motors and the compressor start device one at a time to see if the fault is in an external component rather than the board. If disconnecting external components does not clear the fault, the main control board itself is the likely failure point and will need to be replaced.

Not necessarily. Code 0500 indicates a shorted relay driver output, and if the short originates in an external component like a fan motor or wiring harness rather than inside the board itself, replacing the board will not fix the problem. Worse, installing a new board into a circuit that still has an external short can damage the new board immediately. Isolate and confirm the source of the short before replacing the main control board.

Operating the refrigerator with code 0500 active carries risk. If the relay driver has shorted, the compressor or fans may not be running, meaning food safety is already compromised if temperatures rise above 40 degrees Fahrenheit. Continuing to power a unit with a shorted board output can also cause additional damage to connected components. Check temperatures with a thermometer and address the fault promptly rather than leaving perishables at risk.

If the repair requires a new main control board, parts typically range from $80 to $250 depending on the GE model, with labor adding $100 to $200 if a technician performs the replacement. If the fault traces to a failed fan motor or compressor start device, those parts are generally $15 to $75 and are accessible for confident DIY repair. Accurate diagnosis before ordering parts is worthwhile since replacing a board when the actual fault is a $20 start relay is an avoidable expense.
