Goodman B1370145 300°F Flame Rollout Limit Switch

The Goodman B1370145 is a genuine OEM 300°F manual-reset flame rollout limit switch for the DHS80704BXA gas furnace. Mounted on the burner box, this safety control opens the gas circuit if flame rolls out of the burners due to a blocked heat exchanger or venting problem, shutting the furnace down to prevent overheating and fire. It is a critical safety component.

Specifications

Trip temperature: 300°F
Reset type: Manual (push-button)
Function: Flame rollout safety cutoff
Fits: Goodman DHS80704BXA and compatible furnaces
OEM part number: B1370145

OEM vs. Generic

Genuine OEM rollout switches are calibrated to trip at the exact rated temperature and carry the correct terminal and bracket configuration. Because this is a life-safety device, a mismatched generic switch that trips late — or not at all — poses a serious hazard. OEM replacement is strongly recommended, and repeated tripping should be diagnosed, not bypassed.

Installation Difficulty

Easy to Moderate. Remove two mounting screws, transfer the wire leads, and secure the new switch. Always investigate why a rollout switch tripped — a blocked heat exchanger or vent — before returning the furnace to service.

Never jumper or bypass a rollout switch. Turn off gas and power before servicing.
