The Goodman B1370145 Flame Rollout Switch is a genuine OEM 300°F safety cutout for the AMS81155CNA furnace and other compatible Goodman and Amana gas furnaces. Mounted on the burner box, this normally-closed manual-reset switch trips if flame rolls out of the heat-exchanger — a dangerous condition usually caused by a blocked heat exchanger, restricted flue, or failed inducer. When it opens, it de-energizes the gas valve to stop the burners, protecting the furnace and the home from overheating and combustion hazards.

Specifications

Part number: B1370145
Type: Flame rollout safety switch (normally closed)
Trip temperature: 300°F
Reset: Manual (push-button)
Function: Combustion overtemperature / flame-rollout cutout
Fits: Goodman / Amana AMS81155CNA and compatible 80% furnaces

OEM vs. Generic

As a life-safety device, the genuine OEM Goodman rollout switch is calibrated to trip at exactly 300°F. Aftermarket switches may carry different trip points or reset behavior. Because a mis-rated rollout switch can allow unsafe operation, we recommend only the OEM part for this position.

Installation Difficulty

Easy (1/5). Disconnect power, remove the mounting screws, transfer the wire leads, and mount the new switch in the same orientation. Important: a tripped rollout switch signals an underlying combustion problem — diagnose and correct the root cause before returning the furnace to service. A licensed HVAC technician is strongly recommended.
