Braemar Overtemp Switch 130 Deg

This Braemar overtemp switch is a crucial safety component for residential gas heating systems, helping to prevent damage and ensure safe operation.

Designed to trip at 130 degrees Celsius, it's a manual reset type, specifically for flame roll-out conditions. Overheat switches are a common call-out, especially on older units, so having a reliable replacement on hand saves a lot of time on the job.

Best For

• Residential Braemar ducted gas heaters.
• Service and maintenance technicians working on gas heating systems.
• HVAC apprentices learning gas appliance safety circuits.

Compatibility

This component is designed as a direct replacement for Braemar gas heaters that use the GH-266 part number, primarily for flame roll-out protection. If you're running a different model, check fittings and specs before ordering.

Features

• Braemar OEM replacement part.
• 130 °C trip temperature for reliable overheat protection.
• Manual reset function, ensuring the cause of the overheat is investigated before restart.
• Specifically designed to detect flame roll-out events.
• Identified as Seeley PN: GH-266, cross-compatible with Braemar systems.

What's in the Box

• 1 x Braemar Overtemp Switch 130 Deg Manual Flame Roll Out (PN: GH-266)

Using It on the Job

1. Always isolate power to the gas heating unit at the main switchboard and perform lockout/tagout procedures before commencing any work.
2. Carefully disconnect the wiring from the existing overtemp switch, noting the correct orientation if necessary.
3. Mount the new Braemar overtemp switch securely in the correct location within the heater assembly.
4. Reconnect the wiring, ensuring terminals are clean and connections are tight. Double-check all wiring against the heater's schematic.
5. Restore power and test the heater's operation. If the switch trips, investigate the underlying cause (e.g., blocked flue, combustion issues, faulty fan).
6. Remember, this is a manual reset switch. If it trips, you'll need to press the reset button after addressing the fault.

Limitations & Safety Notes

• Work on gas appliances requires appropriate licensing, such as a licensed gasfitter and potentially a licensed electrician for electrical work. Always check local regulations.
• Always isolate power before handling electrical components.
• Ensure the cause of any flame roll-out or overtemperature condition is fully investigated and rectified, not just the switch reset.
• Only for the compatible Braemar systems listed above.

When an overtemp switch trips, don't just reset it. That switch is telling you there's a problem. Check for blocked flues, combustion air issues, or a failing fan motor. It'll save you a call-back.
