The Goodman B1370145 is a genuine OEM 300°F flame rollout limit switch for the GDS80904BXA gas furnace. Mounted on the burner box, this manual-reset safety opens the ignition circuit and shuts down the furnace if flames roll out of the heat exchanger — protecting against overheating and a cracked heat exchanger. If your furnace trips and needs a manual reset to restart, this switch is doing its job or may have failed open.

Specifications

Trip temperature: 300°F (opens on rise)
Type: manual-reset flame rollout switch
Function: burner box high-temperature safety cutout
Fits: Goodman GDS80904BXA furnace
OEM part number: B1370145

OEM vs. Generic

The OEM Goodman B1370145 is calibrated to the exact 300°F trip point your furnace's safety logic expects, with the correct terminal orientation and mounting bracket. Generic rollout switches may carry the same rating but can differ in reset style and lead placement. Because this is a life-safety component, we strongly recommend the OEM part.

Install Difficulty

Easy (2/5). Cut power at the furnace disconnect, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. About 15 minutes with a nut driver. Always investigate why a rollout switch tripped before resetting.
