Bosch Range PRD304GHU19 Parts

This potentiometer is the rotary sensor behind the control knob. It converts knob rotation into an electrical signal the control board uses to adjust settings, restoring smooth, accurate response when a worn or erratic control causes inconsistent operation.

• Translates knob rotation into a variable-resistance signal for the electronic control
• Enables the control board to regulate power/heat or speed, depending on model
• Common failure symptoms: unresponsive or jumpy settings, dead spots when turning, or settings that drift
• Helps restore precise, repeatable adjustments at the knob

• Disconnect power to the appliance before servicing
• Pull off the knob and open the control panel to access the potentiometer
• Move wires one at a time to the new part; align the shaft/flat to the knob as noted
• Reassemble and test full range of adjustment; follow any model-specific calibration if required
