Goodman B1370145 Rollout Limit Switch (300°F)

The Goodman B1370145 is a genuine OEM flame rollout limit switch rated at 300°F, designed as a direct-fit safety control for the GMV80905CXBA gas furnace. Mounted on the burner assembly, this manual-reset switch instantly cuts power to the gas valve if flames roll out of the burner box — a critical protection against blocked heat exchangers, poor venting, or cracked exchangers. If your furnace locks out on a rollout fault or the switch is open, this is the exact replacement.

Specifications

OEM Part Number: B1370145
Trip Temperature: 300°F (opens on rise)
Type: Manual-reset flame rollout limit switch
Function: Burner-box high-temperature safety cutoff
Fits Model: GMV80905CXBA and compatible Goodman/Amana furnaces
Equipment: Gas Furnace

OEM vs. Generic

Safety controls must trip at the exact rated temperature. The genuine Goodman switch is calibrated to 300°F and carries the correct bracket and terminals for a bolt-in fit. Generic switches may trip early, late, or not at all — a serious hazard on a safety device. Always use OEM for rollout protection.

Install Difficulty

Easy (2 of 5). Two screws and two spade terminals, about 15–20 minutes. Shut off gas and power first. Never bypass a tripped rollout switch — if it keeps tripping, diagnose the underlying cause (venting or heat exchanger) before returning the furnace to service.
