Thermador Range Switch

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.

The Vent Switch is an OEM replacement part for Bosch range hoods. It is an electronic control device located inside the range hood that regulates the internal vent and fan functions.

Causes of a faulty vent switch can include long-term use in high-heat cooking environments, damage from accidental spills or impacts, or normal component degradation over time.

Symptoms include:

• Failure of the fan or vents to engage during cooking  
• Variable or inconsistent fan speeds that don't adequately vent smoke
• Electrical shorting or sparking noises from within the hood control unit

This genuine Bosch replacement part is also compatible with Thermador, Gaggenau, and some Kenmore range hood models.

Burner won't spark or ignite? This spark switch signals the ignition module to light gas burners. Common DIY repair with basic tools, 15-30 minutes.

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

This rotary potentiometer converts shaft rotation into an electrical signal the control board can read, providing precise position feedback for user selections. Replace it if inputs become erratic, jump between settings, or the control stops responding.

• Provides rotary position feedback to the electronic control
• Enables accurate selection and adjustment of functions or setpoints
• Wear or damage can cause drifting, dead spots, or incorrect readings
• Intermittent or no response to input is a common failure symptom

• Disconnect power before servicing
• Access the control/console area to reach the component
• Note shaft orientation and any connector positions; transfer exactly to the new part
• Handle electronics with ESD care and verify smooth, full-range operation after reassembly

Oven won't start or stop correctly? A faulty micro switch prevents proper sensing of linked mechanisms. This switch restores accurate control signals.

This air interlock is the airflow switch that helps monitor and control dryer vent airflow, ensuring the appliance only runs when proper air movement is detected. It replaces a worn or failed interlock to restore normal vent sensing. What it does:

• Senses airflow through the vent and signals the control system to allow or stop operation
• Prevents dryer from starting or continuing a cycle when airflow is restricted
• Common symptom: dryer fails to start, stops mid-cycle, or shows poor drying performance
• Can help address intermittent operation caused by a faulty vent sensing switch

• Disconnect power before servicing to avoid electrical shock
• Handle the switch and wiring gently; verify connector orientation before reinstalling
• Confirm venting is clear and intact when replacing this part

Range burner not heating or stuck on high? This infinite switch controls surface element temperature. Common fix for unresponsive cooktop controls.

This switch assembly replaces a faulty E34 - 19HV switch to restore proper electrical control in the appliance. It provides the same fit and function as the original to help re-enable the affected control circuit safely. What it does:

• Acts as the electrical switch that completes or breaks a circuit when engaged
• Restores normal operation when a failed switch causes intermittent or no response
• Commonly associated with control failures, unresponsive buttons, or power-related symptoms
• Matches OEM form and mounting to fit into the original switch location

• Always disconnect power to the appliance before servicing
• Handle wiring and connectors carefully; note wire locations or take a photo before removal

If your range burner won't heat properly or stays on continuously, the infinite switch may need replacement. This control regulates heat levels.

If your oven won't start or runs with the door open, this door interlock switch detects proper closure and latching. DIY repair in under an hour.

Burner won't heat or stays on high? This infinite switch restores variable temperature control to your range surface element. Direct fit replacement.

Fix a microwave that won't start or respond to controls with this control module switch. Restores proper electrical operation when the original switch fails.

This door switch interlock assembly is the door latch switch that detects and secures the dishwasher door so cycles can start and run safely. It restores proper door sensing and locking for normal operation. What it does:

• Detects when the dishwasher door is fully closed so the control will allow a wash cycle to start.
• Locks or interlocks the door during operation to prevent accidental opening and stop leaks.
• Helps resolve symptoms such as the dishwasher not starting, control lights flashing, or cycles stopping when the door is closed.
• Works as the electrical/mechanical interface between the door and the appliance control.

• One door switch interlock assembly

• Disconnect power to the appliance (unplug or shut off breaker) before beginning repair.
• Remove the dishwasher door panel or access panels as required to reach the latch; keep screws/fasteners organized.
• Align and secure the new interlock assembly and test door engagement and cycle start before reassembly.
