Goodman B1370145 Flame Rollout Switch — 300°F

The Goodman B1370145 is a genuine OEM flame rollout limit switch rated to open at 300°F, built for the Goodman GMNT090-5B gas furnace and compatible GMNT-series units. Mounted on the burner box, this manual-reset safety switch shuts off the furnace if flames roll out of the burner area — a condition caused by blocked flue, cracked heat exchanger, or poor combustion. It is a critical life-safety component.

Specifications

Type: Flame rollout limit switch (manual reset)
Open temperature: 300°F
Action: Opens on temperature rise, breaks control circuit
Mount: Burner-box bracket
Fits: Goodman GMNT090-5B and compatible GMNT furnaces
OEM Part Number: B1370145

OEM vs. Generic

Because this is a safety switch, an exact trip temperature and correct mounting are essential. This OEM switch is calibrated to Goodman's 300°F specification. Generic switches may vary in trip point or terminal style. For any safety limit, we recommend genuine OEM.

Installation Difficulty

Easy — A two-wire swap on the burner box once power is off. If the switch tripped, always diagnose and correct the root cause (blocked venting, heat exchanger, or combustion issue) before returning the furnace to service. Professional inspection recommended.
