The Goodman B1370155 Auxiliary Limit Switch is a genuine OEM safety control engineered as a direct-fit replacement for the AMH80703ANAB gas furnace and other compatible Goodman/Amana equipment. This normally-closed thermal switch opens the control circuit when it senses an overheat condition, shutting the burners down to protect the heat exchanger and surrounding components. A failed auxiliary limit is a common cause of intermittent no-heat lockouts and short-cycling.

Specifications

Trip temperature: 120°F (auto-reset)
Function: Auxiliary / rollout overheat protection
Configuration: Normally closed (opens on rise)
Mounting: OEM bracket / snap-disc style
Compatibility: AMH80703ANAB and compatible Goodman/Amana furnaces

OEM vs. Generic

Our OEM B1370155 is calibrated to the exact factory trip point, guaranteeing correct safety operation and preserving your equipment warranty. A generic universal limit switch may cost less but can trip early, trip late, or fail to seat in the OEM bracket — risking nuisance shutdowns or unsafe operation. For a life-safety component, we recommend genuine OEM.

Installation Difficulty

Easy (1/5) — Cut power at the disconnect, unplug the two spade terminals, remove the mounting screws, swap in the new switch, and reconnect. Typically a 10–15 minute repair with a nut driver. No refrigerant or gas work required.
