Frigidaire Cooktop Error Code E2

E2 on a Frigidaire cooktop indicates a defective key sensor in the left front cook zone control. The cooktop's diagnostic system has detected an abnormal or missing signal from that zone's touch sensor. This can be caused by a faulty sensor, a loose cable connection, or a damaged wiring harness between the left zone control and the main power control board.

The E2 error typically disables or locks out the left front burner zone, making it unreliable or non-functional. You should avoid attempting to use that burner zone until the fault is resolved. The remaining zones may still operate, but continued use with an active error code is not recommended until the root cause is identified.

Repair costs vary depending on the root cause. If only a cable connection needs to be reseated, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the left front zone control panel assembly or the main power control board requires replacement, total repair costs including parts and labor can range from $150 to $400 or more depending on the specific model and part pricing.

Some causes of E2 are DIY-accessible, particularly checking and reseating the cable connections between the left side zone control and the main power control board. However, if the key sensor or control panel assembly needs replacement, the repair involves disassembling the cooktop and working near line voltage components, which is best handled by a qualified technician.

Disconnecting power to the cooktop for several minutes may temporarily clear the E2 code, but if the underlying fault in the key sensor or wiring remains, the error will return when the cooktop is powered back on. A reset is useful for confirming whether the fault is persistent or intermittent, but it does not repair the defective component.
