Goodman B1370145 300°F Rollout Limit Switch

The Goodman B1370145 is a genuine OEM flame-rollout limit switch rated to trip at 300°F, built for the Goodman/Amana DMS80453ANA gas furnace. This manual-reset safety opens the gas circuit if flames roll out of the burner box — protecting against a blocked heat exchanger or restricted flue. A tripped or fatigued switch will shut the furnace down and must be replaced with the exact temperature rating.

Specifications

Part Number: B1370145
Type: Flame Rollout Limit Switch (manual reset)
Trip Temperature: 300°F
Fits: Goodman/Amana DMS80453ANA furnaces
Equipment: Gas Furnace (burner-box safety)
Brand: Goodman (OEM)

OEM vs. Generic

Rollout switches are a life-safety component; a generic with a mismatched trip point or slow response can fail to protect the equipment. The OEM Goodman B1370145 is calibrated to the factory 300°F setpoint with the correct bracket and terminal orientation for a proper, code-compliant fit.

Installation Difficulty

Easy (2/5). Disconnect power, note or photograph the two spade terminals, remove the mounting screws, and install the new switch in the same position. Important: a repeatedly tripping rollout switch signals a real combustion or venting problem — have the heat exchanger and flue inspected rather than simply resetting. Typical job time is 15 minutes.

Keep your furnace protected with the genuine Goodman B1370145.
