GE Range Error Code F5E3

F5E3 indicates that the control board has detected a loss of 120 VAC between L1 and ground, or a failure in the Q19 transistor circuit on the control board itself. The range monitors this voltage reference to ensure safe and proper operation. The fault can originate from a grounding problem in the home's wiring, a supply cord issue, or an internal control board failure.

A reset by cutting power at the breaker for a few minutes may temporarily clear the code, but the fault will return if the underlying cause has not been fixed. If the ground connection is faulty or the control board's Q19 circuit has failed, the error will come back as soon as the range attempts normal operation. A reset is useful for confirming the fault is persistent, but it is not a repair.

If the fix involves tightening connections or replacing a supply cord, costs are relatively low, typically in the range of $20 to $80 for parts and minimal labor. If the main control board needs replacement, parts alone can range from $150 to $350 or more depending on the specific model, with professional labor adding additional cost. Getting an accurate estimate requires identifying the root cause first.

No, you should not operate the range while this error is active. An F5E3 code points to a potential power supply or grounding fault, which can create a shock hazard or lead to unpredictable operation of heating elements. Disconnect power to the range at the breaker until the issue is properly diagnosed and repaired.

Start by checking the ground wire and all connections at the range's terminal block for looseness, corrosion, or damage. Next, test both legs of the incoming supply at the terminal block with a multimeter to confirm 120 VAC from each hot leg to ground. If the power supply and grounding are correct, the main control board will need to be replaced due to a failed Q19 circuit.
