Bosch 12033465 Thermocouple

Product Description

The BOSCH 12033465 is a replacement thermocouple designed for use in gas-fired home appliance systems. A thermocouple is a safety and sensing device that monitors pilot flame presence and generates a small millivolt signal to hold the gas valve open. If the pilot flame is lost, the thermocouple cools, the signal drops, and the valve closes automatically, preventing unburned gas from accumulating. This part is a direct OEM replacement component sourced from Bosch and is typically installed by a licensed gas appliance technician or qualified service professional.

This thermocouple is applicable to Bosch home appliance systems that rely on a standing pilot ignition setup. Common install scenarios include service calls where the existing thermocouple has failed, corroded, or no longer produces a sufficient millivolt output to hold the gas valve open. It is suited for residential gas appliance applications where an OEM-quality replacement is required to restore proper pilot safety operation.

Key Features

• OEM replacement thermocouple from Bosch for reliable millivolt output performance
• Designed to restore pilot flame safety shutoff function in gas appliance systems
• Direct replacement fit reduces diagnostic and installation time
• Sourced from Bosch Parts and Accessories for confirmed OEM specification

Compatibility

Designed as an OEM-style replacement thermocouple for Bosch home gas appliance systems utilizing a standing pilot ignition configuration.

Installation Notes

Installation should be performed by a licensed gas appliance technician or qualified service professional in accordance with local codes and the appliance manufacturer guidelines. Shut off the gas supply fully and allow all components to cool before handling the thermocouple. The thermocouple connection nut should be hand-tightened then snugged with a wrench — do not overtighten, as this can damage the fitting. Verify pilot flame engulfs the thermocouple tip correctly after reinstallation before returning the appliance to service.
