Jenn-Air Cooktop Error Code Er 36

Er 36 means the cooktop's control unit has detected that the NTC thermistor sensor signal is outside its valid voltage range, specifically below 200 mV or above 4.9 V. This indicates either a short circuit or an open circuit condition in the temperature sensing circuit. As a safety response, the control unit shuts off the cooktop to prevent uncontrolled heating. The fault typically points to a failed control board, a bad NTC sensor, or damaged wiring connecting the two.

No, you should not attempt to use the cooktop while Er 36 is active. The control unit has cut off operation because it cannot reliably monitor the cooktop's temperature, which is a critical safety function. Operating the unit without proper temperature monitoring could result in overheating or component damage. Restore normal function by completing the required repair before resuming use.

A power reset alone is unlikely to permanently clear Er 36 because the code is triggered by an out-of-range hardware reading from the NTC circuit. If the underlying fault in the sensor, wiring, or control board is still present, the error will return after power is restored. A reset may temporarily clear the display, but the cooktop will detect the fault again once it attempts to monitor temperature. A proper component repair or replacement is necessary to resolve the code.

The specified repair procedure involves disconnecting power, replacing the UI control board, reassembling all parts and panels, and reconnecting power. A knowledgeable DIYer comfortable with appliance disassembly can perform this repair, but it requires identifying the correct replacement board for the specific cooktop model. Before replacing the board, it is also worth inspecting the NTC sensor wiring harness and connectors for any visible damage or loose connections.

Repair costs vary depending on whether the fault is in the control board, the NTC sensor, or the wiring harness. A replacement UI control board for a Jenn-Air cooktop typically ranges from around 80 to 250 dollars for the part alone. Adding professional labor for diagnosis and installation generally brings the total repair cost to somewhere between 150 and 450 dollars, depending on service rates in your area.
