Starter Relay Parts

This wire harness connects the control/switch assembly to the appliance's thermal cutoff and control circuits, restoring reliable electrical connections for proper operation. It's a direct-fit replacement when the original wiring is damaged or corroded. What it does:

• Provides the factory routing and connectors between the control/switch and TCB/thermal cutoff
• Re-establishes lost or intermittent power caused by damaged wiring or broken terminals
• Helps stop failures that cause controls to be unresponsive or cycles to stop unexpectedly
• Uses OEM-style terminals and insulation to match original fit and function

• One wire harness (switch TCB) as shown

• Disconnect power before starting — verify the appliance is completely de-energized
• Take photos of existing wire routing and connector locations to ensure correct reassembly
• Plug connectors fully and secure the harness along original clips or tie points; avoid sharp edges
• If terminals are damaged at mating parts, inspect and replace those components rather than splicing connectors

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

This pressure switch monitors the water level inside the washer tub and signals the control board when the correct fill level has been reached. It connects to a small air hose that runs to the tub. Replace this switch if your washer overfills, underfills, does not fill at all, or fails to advance past the fill cycle.

Freezer won't cool or compressor won't start? This compressor start relay restores reliable startup and cooling. Located in the compressor compartment.

Fix a refrigerator that won't cool or compressor runs briefly then stops. This PTC starter relay provides timed boost to start winding for reliable cooling.

Compressor won't start or runs intermittently? This start relay and overload helps the motor get up to speed so your refrigerator runs reliably again.

Fix cooktop electrical failures or unresponsive controls with this wire harness. Restores power and signal connections between components.

This control component allows selection of different heat settings and is located on the dryer's control panel. Replace it if you can't select certain temperature settings, the dryer runs too hot or cold, or the switch feels loose or unresponsive.

This is an electrical relay used in the washer's motor or control circuit to switch power to specific components during operation. It helps regulate the timing and function of the wash and spin cycles. Replace this relay if the washer motor won't start, the machine hums but doesn't agitate or spin, or if cycles fail to advance properly.

Burner won't adjust heat or jumps to full power? This infinite switch restores variable temperature control to surface burners. DIY install in 30 minutes.

This is a spark ignition switch used on gas ranges and cooktops to detect burner position and activate the igniter when the knob is turned. It sends a signal to the spark module to generate the electric spark that lights the gas burner. Replace this switch if a burner fails to spark when turned on, sparks continuously even after the flame is lit, or if the igniter clicks but won't stop.

This push-button switch controls electrical power or function circuits in compatible Bosch appliances, restoring user input and on/off control when the original switch fails. What it does:

• Opens or closes the appliance's electrical circuit when pressed to enable a given function
• Commonly used where a user-operated control needs a durable, tactile interface
• Resolves symptoms like an unresponsive control panel, intermittent operation, or functions that won't toggle on
• Replaces a worn or non-clicking switch to restore reliable button response

• One replacement push-button switch

• Disconnect power to the appliance before servicing to prevent shock
• Verify correct terminal connections and orientation before final assembly
• Use basic hand tools; avoid forcing connectors to prevent damage

Fix washer overfilling or incorrect water levels with a new pressure switch. Solves fill problems across load sizes. Most installs in 5-10 minutes.

Washer overfilling or running without water? Your pressure switch likely failed. This switch monitors water levels to prevent overflow problems.
