What the SUPPLY MISWIRED error code actually means

Your GE range is detecting that the electrical wiring connected to it is not set up correctly, which could mean the wrong wires are on the wrong terminals or there is a problem with the electrical outlet or circuit it is plugged into. The range has a built-in safety monitor that checks the incoming power and will not operate normally until the wiring issue is resolved. This is an electrical supply problem, not a range component failure, and it should be diagnosed by a qualified technician if you are not comfortable working with household wiring.

Questions people ask about SUPPLY MISWIRED

What does SUPPLY MISWIRED mean on a GE range?
SUPPLY MISWIRED means the range's power monitor has detected that the incoming 240VAC electrical supply is not wired correctly. Specifically, it checks the voltage between L1, L2, and neutral, and flags an error if those voltages fall outside the expected ranges for a properly wired split-phase circuit. This is a supply-side wiring problem, not a failed component inside the range itself. The range will not operate normally until the wiring is corrected.
Is it safe to use my GE range while the SUPPLY MISWIRED error is displayed?
No, you should not attempt to operate the range while this error is active. A miswired supply can result in incorrect voltages reaching internal components, which can cause component damage or create a shock hazard. The range should remain unplugged or the circuit breaker should be turned off until the wiring issue is properly diagnosed and corrected.
How much does it cost to fix a SUPPLY MISWIRED error on a GE range?
If the issue is simply a wire landed on the wrong terminal at the range's terminal block, the repair cost may be minimal, covering only a service call fee, which typically ranges from $75 to $150 depending on your area. If the problem is at the wall outlet or requires an electrician to correct wiring in a junction box or panel, costs could range from $100 to $400 or more depending on the scope of work. A new power cord, if that is the cause, generally costs between $20 and $60 for the part alone.
Can I fix a SUPPLY MISWIRED error on my GE range myself?
If you are comfortable and qualified working with household 240VAC wiring, you can inspect the terminal block at the back of the range and verify that each conductor is landed on the correct terminal. However, if the problem originates at the wall outlet, junction box, or electrical panel, that work should be performed by a licensed electrician. Never touch any wiring connections while the range is energized.
Will resetting the GE range clear the SUPPLY MISWIRED error?
Resetting the range by cycling the power or tripping the breaker will not permanently clear this error if the underlying wiring problem still exists. The power monitor checks supply voltages during and after power-up, so the fault will return immediately once power is restored to a still-miswired circuit. The error will only stop appearing after the wiring is corrected.
