Temperature Switch

Bradford White 415-41831-00 – OEM Temperature Switch for MITW Series Gas Water Heaters

The Bradford White 415-41831-00 temperature switch is a factory-direct replacement part engineered for use in select atmospheric vent gas water heater models, including MITW40L and MITW50L. This component is designed as a safety cutoff device, triggering at preset temperature thresholds to prevent the system from exceeding safe operating limits. It functions as part of the over-temperature protection mechanism integrated into the burner control assembly.

Functional Purpose

This temperature switch is thermally actuated and intended for single-use operation. If excessive outlet temperatures are detected—typically resulting from a failure in the gas valve, thermostat, or flue blockage—the switch will open the circuit, halting burner operation. Reset requires component replacement. This safety feature is a critical part of the heater’s fail-safe logic.

Product Details

• Part Number: 415-41831-00
• Component Type: Manual-reset temperature switch (non-resettable after trip)
• Compatible Models: MITW40L and MITW50L
• Mounting: Clip-on design integrated into burner assembly
• Temperature Rating: Trips at manufacturer-specified high-limit threshold
• Material: High-temperature-rated thermoplastic housing with integrated wire leads

Installation Requirements

Installation of this safety switch should be performed by a qualified technician. It involves disconnecting electrical power, removing the burner assembly, and verifying system faults prior to replacement. This component does not reset and must be replaced if tripped. All system diagnostics should confirm root cause prior to reassembly.

Contractor Notes

• OEM Specificity: This switch is calibrated for Bradford White gas units with specific burner and control configurations. Substitutions are not advised.
• Compliance: Meets Bradford White factory requirements for UL/CSA-listed water heaters using FVIR technology.
• System Considerations: A tripped switch often indicates secondary failure (e.g., blocked flue, faulty gas valve, or thermocouple degradation). Always perform full system inspection prior to reactivation.

Use Case Summary

This part is primarily used in scheduled service calls for systems presenting with no-heat symptoms due to a tripped safety circuit. It is also commonly stocked by service contractors for quick-response calls on MITW-series water heaters. As an OEM replacement part, it ensures continued safe operation without compromising warranty or performance standards.
