Goodman B1370145 Flame Rollout Switch (300°F)

The B1370145 is a genuine OEM manual-reset flame rollout limit switch engineered for the Goodman ADS81155CNA gas furnace and compatible Goodman/Amana models. Mounted near the burner assembly, this safety device opens the control circuit and shuts down the burners if flame rollout or excessive heat is detected outside the heat exchanger — protecting your home from unsafe combustion conditions. A failed or nuisance-tripping rollout switch is one of the most common causes of a furnace that ignites briefly and then locks out.

Specifications

Trip temperature: 300°F (manual reset)
Type: Normally closed flame rollout limit
Function: Burner safety / combustion shutdown
Fit: Goodman ADS81155CNA and compatible furnaces
OEM Part Number: B1370145

OEM vs. Generic

This is the genuine Goodman OEM switch, factory-calibrated to the exact 300°F trip point your furnace's safety logic expects. Generic universal rollout switches may carry a similar rating but can vary in bracket geometry, lead length, and trip tolerance, leading to nuisance lockouts. For a safety-critical combustion component, OEM is strongly recommended.

Installation Difficulty

Easy — typically a 10–15 minute repair. Disconnect power, unplug the two spade terminals, remove the mounting screws, and swap. A multimeter to confirm continuity is helpful. Because this part affects combustion safety, have a licensed HVAC technician verify operation if you are unsure.
