Goodman B1370154 350°F Flame Rollout Switch

The B1370154 is a genuine Goodman OEM flame rollout switch rated to open at approximately 350°F, built for the GMN100-4 gas furnace. Mounted near the burner assembly, this manual-reset safety control shuts off the gas valve if flame rolls out of the burner box due to a blocked heat exchanger, cracked flue, or poor venting. It is a critical safety device — a tripped or failed rollout switch will keep the furnace from firing until the underlying condition is corrected and the switch is reset or replaced.

Specifications

Open temperature: ~350°F
Type: Flame rollout, manual reset, normally closed
OEM Part Number: B1370154
Fits: Goodman GMN100-4 and compatible furnaces
Function: Flame rollout / over-temperature safety cutout
Brand: Goodman / Amana

OEM vs. Generic

The OEM Goodman rollout switch is calibrated to the precise 350°F trip point and bracket geometry required for correct burner-box placement. A generic switch with a different set point can trip late — or not at all — compromising a life-safety function. Always use the OEM-spec part for rollout protection.

Install Difficulty

Easy — Single mounting screw or bracket clip with two spade terminals. A quick swap, but if the switch tripped, diagnose the cause (blocked exchanger/venting) before returning the furnace to service. Shut off gas and power first.
