Goodman B1370145 Flame Rollout Switch (300°F)

The Goodman B1370145 is a genuine OEM flame rollout limit switch rated to open at 300°F, designed for the DMS80703ANA gas furnace and compatible Goodman/Amana models. Mounted on the burner assembly, this manual-reset safety device instantly cuts power to the gas valve if flames roll out of the burner box — a dangerous condition usually caused by a blocked heat exchanger, poor venting, or a failing inducer. When it trips, the furnace will not restart until the fault is corrected and the button is reset.

Specifications

Trip temperature: 300°F (opens on rise)
Reset type: manual push-button
Function: flame rollout safety cutoff
Terminals: 1/4in quick-connect spade
Fits: Goodman DMS80703ANA and select 80% AFUE furnaces
OEM part number: B1370145

OEM vs. Generic

Because this is a life-safety component, the genuine Goodman switch is calibrated and UL-listed to the exact trip point and mounting footprint the furnace was certified with. Generic replacements may have slightly different open temperatures or bracket geometry, which can cause nuisance trips or improper burner-box protection. OEM is strongly recommended for any rollout switch.

Install Difficulty: Easy (2/5)

Shut off power, note or photograph the two wire positions, unscrew the switch from the burner bracket, transfer the wires, and remount. Fifteen minutes with a nut driver. Always diagnose why the original tripped before replacing.
