Customer Questions and Answers for Potentiometer by Bosch

Manufacturer Part Number: 00422748

The Potentiometer is an OEM replacement part for Bosch gas range or cooktops. It functions as a three-terminal resistor that adjusts the flow of electric current, which in turn, controls the ignition and temperature of the cooktop. This component is essential for the precise operation and control of the gas burners, ensuring they light up and maintain the desired flame intensity.

Causes of a malfunctioning Potentiometer can be attributed to wear and tear, electrical issues, or damage due to spills and cleaning products. A compromised potentiometer affects the flow of electric current, leading to issues with the ignition and temperature control of the gas burners.

Symptoms of a bad Potentiometer include:

  • The cooktop not lighting or staying lit
  • The ignitor continuously clicking without igniting the burner
  • Inability to adjust the flame intensity or temperature accurately

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.

Questions & Answers

For Bosch Potentiometer (Part Number: OEM11348934)

1 Answer

Hello Bryan. If you get spark, then the potentiometer is good. If the solenoid is new, and the orifice is clean, your next step would be replacing the gas valve for that burner.

George, The potentiometer for your unit would be 00422748 and would just unplug the wire harness from the old and install on the new potentiometer.

Hello Jim, This is the correct potentiometer for your unit but be aware that these potentiometers are not compatible with the old simmer control. You should replace the parts with the kit 00497234. This kit comes with two potentiometers which are not compatible with the old simmer control.

Hello Rainer, We will need your complete model number to look up the exact part for your unit. I'm sorry for the inconvenience but this is necessary to obtain the harness that will work on your unit. In case we cannot locate the part number and have to submit the information to the manufacturer, we may have to also have the serial number. Thank you for your patience and understanding in this matter.

Ernest for Model Number PRG304us

Ignitor control module replaced two months ago: all ok until now. Today all 4 ignitors continue clicking without provocation! I lifted all ignitors and cleaned and dried them...yes getting shocked often! Also notice LF simmer burner does NOT always ignite...and occasionally turns off when turning knob from full to lower position. Seems to have lost its "detent" from low to potentiometer-simmer too. Sometimes turning on LR burner allows LF to ignite more often, but rarely will LF burner ignite by itself. SOLENOID or front SIMMER-POT?? Are the two problems related? Can't imagine it's the ignitor control module again, as it's so new.... Again, LF gas valve DOES open sometimes, so I suspect the solenoid is ok...but not getting triggered by the simmer-board pot assy?? Thanks! Ern

Ernest, For the left burner issue this would most likely be a bad potentiometer. For the issue of all of the burners sparking, it would be either bad wiring or a bad spark module.
