The genuine Goodman B1370145 is a 300°F flame rollout switch engineered for the Goodman DDS81155CXA furnace and compatible Goodman and Amana gas models. Mounted on the burner assembly, this manual-reset safety device instantly cuts power to the gas valve if flames roll out of the burner box — a dangerous condition typically caused by a blocked heat exchanger, cracked flue, or restricted venting. It is a critical life-safety component that should never be bypassed.

Trip Temperature: 300°F
Type: Manual-reset flame rollout switch
Contacts: Normally closed, opens on overtemperature
Fit: Direct OEM replacement for DDS81155CXA
Brand: Goodman / Amana genuine OEM

OEM vs. Generic

Genuine Goodman B1370145 switches are calibrated to trip at the precise 300°F threshold your furnace's safety circuit is designed around, with a mounting footprint that matches the burner assembly exactly. Generic rollout switches may trip early (nuisance shutdowns) or late (unsafe), and often require bracket modification. On a safety cutoff, matching the OEM specification is essential.

Installation Difficulty: Easy (2/5)

Shut off power and gas, remove the two mounting screws, transfer the spade wire connectors to the new switch, and reinstall. If the old switch had tripped, diagnose and correct the underlying cause — a repeated rollout trip signals a serious combustion or venting problem.
