GE Cooktop Error Code Er47

Er47 indicates a bad communication signal between the touch board and the filter board through the ribbon cable that connects them. The cooktop's control system detected that data is not passing correctly between these two components. This fault will typically prevent normal cooktop operation until the issue is resolved.

You should not attempt to use the cooktop while Er47 is active. The error indicates a breakdown in the internal control communication, which means the cooktop may not respond to commands correctly or at all. Attempting to operate it in this state is not recommended until the fault is diagnosed and repaired.

If only the ribbon cable needs to be replaced or reseated, costs are minimal, generally in the range of a few dollars to around $20 to $40 for a replacement cable if the original is damaged. Filter board replacement typically costs between $80 and $200 or more for the part depending on the model, plus labor if a technician performs the repair. Getting a diagnostic visit from a qualified technician usually runs between $75 and $150 before parts.

Some cases of Er47 can be resolved without replacing parts by reseating the ribbon cable connecting the touch board to the filter board. This requires accessing the cooktop's internal components, so comfort with basic appliance disassembly is needed. If reseating the cable does not clear the fault, the filter board will likely need to be replaced, which is a more involved repair.

A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the error if the fault is intermittent, but it will return if the underlying issue with the ribbon cable or filter board is not corrected. A reset is not a fix and should only be used as part of the diagnostic process to confirm whether the fault is consistent.
