Goodman B1370145 300°F Flame Rollout Limit Switch

The B1370145 is a genuine OEM Goodman flame rollout limit switch with a 300°F trip point. This manual-reset safety device mounts on the burner box and instantly cuts power to the gas valve if flames roll out of the burner compartment — protecting against overheating from a blocked heat exchanger, poor venting, or dirty burners. It is an exact-fit replacement for the Goodman DDS80904BXA gas furnace and compatible Goodman/Amana models.

Specifications

Trip temperature: 300°F (manual reset)
Type: Normally-closed flame rollout / limit switch
Function: Safety cutout to gas valve control circuit
Fits: Goodman DDS80904BXA and compatible furnaces
OEM Part Number: B1370145

OEM vs. Generic

Our OEM Goodman switch is calibrated to the exact 300°F factory trip point — essential for a safety component where an incorrect setpoint can nuisance-trip or fail to protect. A Generic equivalent matches the 300°F manual-reset spec at a lower price for out-of-warranty repairs. Because this is a life-safety device, we recommend the OEM part for guaranteed calibration.

Installation Difficulty

Easy (2/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same orientation on the burner box. If the switch tripped, always diagnose the root cause (heat exchanger, venting, airflow) before returning the furnace to service.
