GE Refrigerator Error Code 0506

Error code 0506 on a GE refrigerator signals a problem with the hot water temperature and pressure (T&P) switch or its associated wiring. The control board has detected that it cannot receive a valid signal from this safety switch. The code requires inspection of both the switch and the wiring circuit before the appliance can resume normal operation.

Yes, this code relates to the hot water T&P switch, which is a safety component that monitors temperature and pressure in the hot water system. Operating the appliance with this fault unresolved could mean the system lacks proper safety monitoring. It is advisable to address this error promptly rather than continuing to use the appliance.

A power reset may temporarily clear the code from the display, but it will return if the underlying fault in the T&P switch or wiring has not been corrected. The error must be resolved by diagnosing and repairing the actual cause. Relying on resets without fixing the root issue is not a long-term solution.

Start by inspecting the wiring harness connected to the T&P switch for loose connectors, corrosion, or visible damage. Reseat any connectors that appear loose and repair or replace any damaged wiring. If the wiring checks out, test the T&P switch itself for continuity and replace it if it has failed.

Repair costs depend on what component is at fault. If only a wiring connector needs to be reseated or a wire repaired, costs are minimal. Replacing the T&P switch itself typically ranges from $50 to $150 for the part, plus any applicable labor costs if a technician performs the repair.
