GE Refrigerator Error Code F80

The F80 code means the control board is receiving an input signal from the hot water Temperature and Pressure switch when that signal should not be present. This indicates either a faulty switch that is stuck closed, a short circuit in the wiring, or a damaged connector. The first step is to inspect the T&P switch and its wiring harness for visible damage or continuity issues.

The F80 code itself signals a fault in a safety monitoring circuit, which means the refrigerator may not be correctly tracking temperature and pressure conditions that the T&P switch is intended to guard against. It is advisable to address the fault promptly rather than continuing to operate the appliance with a known safety circuit issue.

If only the T&P switch needs replacement, parts costs are typically modest, often in the range of $15 to $60 depending on the specific component. If a control board replacement is required, costs can rise significantly, generally between $100 and $300 or more for the part alone. Adding professional labor will increase total repair costs, usually ranging from $150 to $400 depending on the complexity of the repair and local service rates.

A knowledgeable DIYer can start by inspecting the wiring harness and connectors for visible damage, corrosion, or pinching, which requires no special tools. Testing the T&P switch for continuity requires a basic multimeter. If the switch tests faulty or the wiring is damaged, component replacement may be needed and comfort level with appliance wiring should guide the decision to proceed or call a technician.

A reset may temporarily clear the code from the display, but it will return if the underlying fault in the T&P switch circuit is still present. Resetting without addressing the root cause is not a repair. The wiring and switch must be inspected and corrected before the code will clear permanently.
