GE Cooktop Error Code F73

F73 on a GE cooktop indicates a User Interface key fault, meaning the control system has detected that one or more keys on the control panel are registering as stuck, shorted, or otherwise not functioning correctly. This can be caused by surface contamination, a wiring issue, or a failed UI board. The cooktop flags this code to prevent unintended operation caused by a faulty input.

It is not recommended to continue using the cooktop while the F73 fault is active. A UI key fault can cause unpredictable control behavior, including unintended element activation or incorrect temperature settings. Power off the cooktop at the circuit breaker until the fault has been diagnosed and resolved.

If the fault is resolved by cleaning alone, there is no parts cost involved. If a UI board replacement is required, parts typically range from around 80 to 200 dollars depending on the specific cooktop model, with professional labor adding another 100 to 200 dollars or more depending on your location and service provider. Diagnosing the cause accurately before ordering parts helps avoid unnecessary expenses.

Yes, in many cases the F73 error can be resolved without replacing any parts. Start by thoroughly cleaning the control panel surface to remove any grease, spills, or debris that may be causing a key to read as continuously active. After cleaning, cycle the power at the circuit breaker for at least 30 to 60 seconds and restore it to see if the fault clears. If the error returns after cleaning and power cycling, a UI board replacement will likely be needed.

A power reset by turning off the circuit breaker for 30 to 60 seconds and restoring power can clear the F73 code if the fault was caused by a temporary electronic glitch. However, if the underlying cause is physical contamination on the panel or a failed UI board, the error will return after the reset. Cleaning the panel before or alongside the reset improves the chances of a lasting resolution.
