KitchenAid Cooktop Error Code Er32

Er32 means the touch control board connected to the cooktop is designed for a different zone configuration than the unit it is installed on. This happens when a 2-zone touch control is paired with a 4-zone cooktop, or a 4-zone control is paired with a 2-zone cooktop. The error indicates a hardware mismatch, not a sensor fault, and the cooktop will not operate normally until the correct board is installed.

Start by identifying the exact model number of the cooktop and locating the part number printed on the currently installed touch control board. Compare that part number to the correct specification for the model to confirm a mismatch. If the wrong board is installed, the correct zone-matched touch control board must be ordered and installed to resolve the error.

The primary cost involved is the replacement touch control board, which typically ranges from roughly $80 to $250 or more depending on the specific model and zone configuration. If a technician is hired to install the part, labor costs commonly range from $75 to $150 per hour. In many cases, if the wrong part was recently purchased, the supplier may accept a return or exchange, which can reduce out-of-pocket expense.

No, resetting the cooktop will not clear Er32. This error reflects a fundamental incompatibility between the touch control board and the cooktop's zone configuration, so the fault will return immediately after any reset attempt. The only way to resolve it is to install the correct replacement touch control board that matches the cooktop's zone count.

The cooktop is not intended to operate normally while Er32 is active, as the control mismatch prevents the unit from functioning as designed. Attempting to use the cooktop in this state is not recommended, since the touch controls may not correspond correctly to the heating zones. The error should be resolved by installing the correct replacement part before resuming use.
