The genuine Goodman B1370145 is the OEM 300°F flame rollout limit switch for the GMV81155CXA furnace and many other Goodman/Amana models. This safety device sits near the burner assembly and trips if flames roll out of the burner box — shutting off the gas valve to prevent overheating and fire. If it opens, the furnace locks out and won't fire, protecting the equipment and the home.

Specifications

Part number: B1370145
Trip temperature: 300°F (opens on rise)
Reset: Manual reset button
Type: Flame rollout safety limit switch
Fits: Goodman GMV81155CXA and compatible GMV furnaces

OEM vs. Generic

Safety limits must trip at the exact rated temperature. The OEM B1370145 is calibrated to Goodman's 300°F spec with the correct terminal and bracket. Substituting a mismatched-temperature or off-brand switch can defeat a critical safety function — never guess on a rollout switch. Always use the correct OEM part.

Install Difficulty

Easy (2/5). De-energize the furnace, note wire positions, remove two mounting screws, transfer the spade terminals, and remount. About 10 minutes. If a rollout switch has tripped, always diagnose the root cause (cracked heat exchanger, blocked flue, dirty burners) before returning the unit to service.
