Goodman B1370145 Flame Rollout Switch (300°F)

The Goodman B1370145 is a genuine OEM 300°F manual-reset flame rollout limit switch for DHS80905CXA and compatible Goodman/Amana furnaces. Mounted on the burner box, it opens the ignition circuit if flames roll out of the burner compartment — a critical safety device that shuts the furnace down before heat can damage components or escape the cabinet. A tripped or failed rollout switch is often the sign of a blocked heat exchanger or restricted venting.

Specifications

Part number: B1370145
Trip temperature: 300°F (open on rise)
Reset: Manual (button)
Type: Normally closed flame rollout limit
Fits: Goodman/Amana DHS80905CXA and related furnaces

OEM vs. Generic

Safety limits must match the exact trip temperature and mounting the furnace was certified with. The OEM 300°F switch guarantees the correct cutoff point and terminal spacing. Never substitute a higher-temperature switch to stop nuisance trips — diagnose the root cause instead.

Install Difficulty

Easy — Cut power, unplug the two spade terminals, remove the mounting screws, and install the new switch. Important: If the old switch tripped, find and fix the underlying combustion or venting fault before running the furnace.
