Thermador Cooktop Error Code Er32

Er32 indicates a compatibility mismatch between the installed touch control module and the cooktop's induction zone configuration. The cooktop has detected that the touch control is designed for a different appliance type, either a 2-zone unit connected to a 4-zone cooktop or vice versa. This error is directly related to a hardware mismatch and requires verifying that the correct touch control part is installed for the specific model.

No, resetting the cooktop will not clear Er32. This error is caused by a hardware incompatibility between the touch control module and the appliance configuration, not a temporary software or communication fault. The error will return every time the cooktop powers on until the correct touch control is installed.

The cost depends on whether a replacement touch control module is needed and whether professional installation is required. Touch control modules for Thermador induction cooktops typically range from around $150 to $400 or more depending on the specific model. If a technician is needed for diagnosis and installation, labor costs will add to that total, generally ranging from $100 to $250 depending on your area.

The fix for Er32 is to confirm that the touch control module installed in your cooktop matches the appliance's induction zone count. Locate the model number on the cooktop's rating label and cross-reference it against the specifications of the installed touch control. If the wrong part is installed, replacing it with the correct TC for your cooktop model will resolve the error.

When Er32 is active, the cooktop will not operate normally because the control system has detected a configuration mismatch. Attempting to use the cooktop in this state is not recommended, as the touch control and the induction zone hardware are not communicating as intended. The cooktop should remain out of service until the correct touch control is installed.
