GE Range Error Code F73

F73 indicates that the RPSM (Range Power Supply Module) has detected an error in the incoming line power. The RPSM monitors the 240V AC supply to the range and triggers this code when it detects a dropout or interruption. The fault can originate from the household electrical supply or from the RPSM module itself.

Operating the range while an F73 fault is active is not recommended. A line power error can indicate unstable voltage conditions that may affect the safe and proper operation of the appliance. The range should remain off until the electrical supply and the RPSM have been inspected and the fault resolved.

Repair costs vary depending on the root cause. If the issue is a loose connection or a tripped breaker, costs may be limited to a service call fee, typically in the range of $75 to $150. If the RPSM requires replacement, parts and labor combined can run from $150 to $400 or more depending on the specific model and your location.

Some steps are DIY-friendly, such as checking that the range's power cord is fully seated and inspecting the circuit breaker for signs of tripping. However, testing voltage at the terminal block and diagnosing or replacing the RPSM involves working with 240V wiring, which should only be performed by a qualified technician. If you are not experienced with high-voltage electrical work, professional service is strongly recommended.

Resetting the range by cycling the circuit breaker or unplugging it may temporarily clear the F73 code, but if the underlying cause is not addressed, the code will return. A reset is useful for confirming whether the fault was caused by a one-time power event, but persistent or recurring F73 codes require further diagnosis of the power supply and the RPSM.
