Goodman B1370145 Flame Rollout Switch 300°F

The Goodman B1370145 is a genuine OEM manual-reset flame rollout switch rated to trip at 300°F, built for the DDS80453AXA gas furnace and compatible Goodman/Amana models. Mounted on the burner box, this critical safety limit senses flame rollout caused by a blocked heat exchanger, restricted flue, or failing inducer, and instantly cuts power to the gas valve to prevent fire and CO hazards.

Specifications

Part number: B1370145 (OEM Goodman)
Trip temperature: 300°F
Type: manual-reset flame rollout limit switch
Contacts: normally closed, opens on overtemp
Compatible model: DDS80453AXA gas furnace

OEM vs. Generic

The OEM switch carries the exact 300°F calibration and mounting footprint the furnace's safety circuit is designed around. A generic rollout switch may differ in trip point or bracket, and because this is a life-safety device, we strongly recommend OEM for guaranteed calibration.

Installation Difficulty

Easy (2/5). Disconnect the two spade terminals, unscrew the switch from the burner box, and mount the replacement. If a rollout switch tripped, always diagnose the root cause (blocked exchanger/flue) before resetting. Cut all power to the furnace before servicing.

Fits Goodman DDS80453AXA. Verify trip temperature stamped on your old switch.
