Goodman B1370108 Flame Rollout Switch (300°F)

The Goodman B1370108 is a genuine OEM flame rollout limit switch rated at 300°F, built for GUPI100-5 gas furnaces and compatible GUPI100-series equipment. This manual-reset safety switch cuts power to the gas valve if flames roll out of the burner box due to a blocked heat exchanger, cracked exchanger, or restricted venting. It is a critical last line of defense against overheating and fire.

Specifications

Trip temperature: 300°F
Type: Manual-reset flame rollout limit switch
Function: High-temperature burner safety cutout
OEM Part Number: B1370108
Brand: Goodman
Equipment: Gas Furnace (GUPI100-5 and GUPI100 series)

OEM vs. Generic

The OEM Goodman B1370108 is factory-calibrated to trip precisely at 300°F. Because this is a safety device, an off-spec generic switch can trip early (nuisance lockouts) or, worse, trip late. For any rollout or limit switch, we strongly recommend the genuine OEM part.

Installation Difficulty

Easy (1/5). Remove two spade wires and one or two mounting screws, then install the new switch in the same orientation on the burner bracket. Turn off power first and press the reset button after installing. Under 10 minutes. Important: if a rollout switch has tripped, always diagnose and correct the root cause (heat exchanger, venting) before returning the furnace to service.
