Goodman B1370145 Flame Rollout Switch (300°F)

The B1370145 is a genuine OEM 300°F manual-reset flame rollout limit switch for Goodman GDS80904BNA gas furnaces and compatible 80% AFUE models. Mounted on the burner assembly, it is a critical safety device: if flames roll out of the burner box — usually from a blocked heat exchanger or restricted venting — the switch opens at 300°F and shuts off the gas valve to prevent fire and CO hazards.

Specifications

Trip temperature: 300°F (open on rise)
Reset: manual push-button
Function: flame rollout / high-limit safety cutout
Fitment: Goodman GDS80904BNA and cross-referenced 80% furnaces
Type: direct-fit OEM replacement

OEM vs. Generic

Because this is a life-safety component, the genuine Goodman OEM switch is the right choice — it is calibrated to the exact 300°F trip point and mounting footprint the furnace was designed around. Generic switches with the wrong temperature rating or slow response can compromise protection. Install OEM and confirm the underlying cause (e.g., cracked heat exchanger, blocked flue) before returning the unit to service.

Install Difficulty

Easy (2 of 5). Cut power and gas, remove the two mounting screws, transfer the spade wires one at a time, and mount the new switch. About 15–20 minutes. If the switch tripped, diagnose and correct the root cause before resetting.
