Jenn-Air Cooktop Error Code E5

The E5 code on a Jenn-Air cooktop indicates an error on the filter board caused by either incorrect wiring or a fault on the power board. The filter board manages power conditioning and signal communication within the cooktop's electronics. This error prevents the unit from operating normally until the underlying electrical issue is resolved.

No, you should not use the cooktop while the E5 error is active. The code indicates a fault in the power conditioning or board circuitry, which could pose an electrical risk or cause further damage to the unit. Disconnect power to the cooktop and have the fault diagnosed and repaired before resuming use.

Repair costs for an E5 error vary depending on which component needs to be replaced and local labor rates. Filter board or power board replacements, including parts and professional labor, typically range from around $150 to $400 or more depending on the specific model and part availability. Confirming the correct supply voltage first costs nothing and should always be done before purchasing replacement parts.

Some causes of E5 can be addressed without professional help, such as verifying the cooktop is connected to the correct supply voltage. However, replacing the filter board or power board involves working with high-voltage appliance wiring and internal components, which is best handled by a qualified appliance technician. If you are not comfortable working with appliance electrical systems, contact a professional for this repair.

Simply resetting the cooktop by cycling power is unlikely to permanently clear the E5 error if the underlying cause is a failed filter board, a failed power board, or an incorrect supply voltage. The fault may reappear immediately or shortly after power is restored. The root cause must be corrected, which may require replacing the filter board or power board.
