Customer Questions and Answers for Potentiometer by Bosch

Part Number: OEM11348934
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.

Peterd, The access for the control panel underneath that would be removed. The unit will need to be removed from installation.

Carlos for Model Number PRG364GDUS/01

The far left knob that controls the rear burner is loose. The burners on the left light fine but neither work on XLO simmer. Thermador tech was here looking at something else, and although he didn't open up the range, said I would need a new potentiometer assembly, but that the parts were no longer available. Can you please advise the correct parts that need to be ordered? From what I can see it would be the Switch Resistor Potentiometer (422748), but not sure what else? Would that alone fix the loose knob or does the valve stem also have to replaced?

1 Answer

Carlos, The part number for the potentiometer will be 00422748 and for the knob issue sounds like just the knob but take the knob off and make sure that the shaft is loose.

I own a Thermador Range (Model RDSS30) where the Front Left XLO Burner does not work but the Rear Left XLO Burner works fine. I get spark to the burner but no gas so assuming I need a new Potentiometer for the front left only as the rear left works fine. The Gas Simmer Controller model is SQ003-H but does not have an A or B suffix after the H like I have seen in the Thermador Service Bulletins or on-line. Can I purchase the #422748 Potentiometer and have it work with my current Simmer Controller?

1 Answer

Rich, You will want to check the gas coil to make sure that it is getting power and is not bad. If this checks ok then the issue will be the potentiometer and 00422748 will be correct for your unit.
