Genuine Goodman 300°F Rollout Limit Switch B1370145

Protect your Goodman/Amana AMH81155CXAA furnace and home with this OEM 300°F manual-reset flame rollout switch. Mounted near the burner assembly, it opens the control circuit and shuts off the gas valve if flames roll out of the burner box — a critical safety response to a blocked heat exchanger, restricted venting, or dirty burners. When a rollout switch trips or fails open, the furnace won't fire; this exact-temperature part restores safe operation.

Specifications

OEM Part Number: B1370145
Trip Temperature: 300°F
Type: Manual-reset (normally closed) rollout limit switch
Fits: Goodman & Amana AMH81155CXAA and compatible furnaces
Bimetal disc sensing element with reset button
Spade-terminal connections, factory bracket fit

OEM vs. Generic

This OEM switch is calibrated to the exact 300°F trip point your furnace's safety design requires. Generic switches with a different set point or reset style can trip prematurely or — worse — fail to trip when needed. On a safety component, match the OEM spec exactly; never substitute a higher-temperature switch.

Installation Difficulty

Easy (2/5). Disconnect power, note the two spade wires, unscrew the old switch from its bracket, mount the new one, and reconnect. If the switch tripped, always diagnose the root cause (heat exchanger, venting, airflow) before returning the furnace to service. About 10–15 minutes.
