GE Cooktop Error Code Er31

Er31 indicates that one of the two filter boards in the cooktop is not configured to work with the other filter board. This code only appears on 36-inch GE cooktop models. It points to a configuration mismatch between the two boards rather than a wiring or sensor fault. Resolving it requires replacing the incompatible or misconfigured filter board.

It is not recommended to continue using the cooktop while Er31 is active. The error indicates the filter boards are not communicating correctly, which means the control system cannot fully manage power and signal filtering for the cooking elements. Operating the unit in this state could lead to unpredictable behavior or further component damage.

Repair costs for Er31 typically depend on the price of the replacement filter board and labor. Filter board parts for GE cooktops generally range from around 80 to 250 dollars depending on availability and the specific model. Adding professional labor, the total repair cost commonly falls somewhere in the range of 150 to 400 dollars, though prices vary by region and service provider.

The diagnostic step for Er31 involves a specific key sequence on the control panel that you can perform yourself to confirm the fault. However, the resolution requires replacing a filter board, which involves working with internal cooktop components and should be handled by someone comfortable with appliance repair. If you are not experienced with disassembling cooktops, a qualified technician is the safer option.

A simple power reset will not clear Er31 because the fault is caused by a physical configuration mismatch between the two filter boards, not a temporary software glitch. The error will return each time the cooktop powers on until the incompatible filter board is replaced with a correctly configured one.
