GE Refrigerator Error Code 28

Error code 28 on a GE refrigerator means the control board has detected a higher than normal current draw from the icemaker solenoid, which is the electrically controlled water inlet valve for the ice maker. This fault can be caused by a shorted solenoid coil, damaged wiring, or a corroded connector. The refrigerator flags this condition to prevent potential damage to the control board or wiring.

A high-current solenoid fault is worth addressing promptly because sustained high current through a circuit can cause wiring insulation to heat up or damage the control board over time. The refrigerator's cooling and food preservation functions typically continue to operate, but the ice maker may be disabled until the fault is resolved.

A power reset may temporarily clear the code from the display, but if the underlying cause, such as a shorted solenoid coil or damaged wiring, has not been corrected, the fault will return once the icemaker solenoid is activated again. A reset is useful for confirming whether the fault is intermittent, but it should not be treated as a fix in itself.

Start by inspecting the wiring connections to the icemaker solenoid for corrosion, damage, or loose pins. Then unplug the solenoid connector and measure the coil resistance with a multimeter. If resistance reads very low or near zero, the solenoid needs to be replaced. If the solenoid and wiring test good, the control board may be the source of the fault.

If the icemaker water inlet solenoid is the cause, replacement parts generally range from $20 to $80 depending on the specific valve assembly. Professional labor to diagnose and replace the component can add $100 to $200 or more. If the control board is determined to be at fault, that repair typically costs significantly more in parts alone.
