The Goodman B1370187 is a genuine OEM 160°F primary limit switch for the Amana/Goodman AMH80703ANAA gas furnace and compatible models. Mounted on the heat-exchanger/burner bulkhead, this primary high-limit is the furnace's main overheat protection: if plenum temperature climbs past the setpoint — usually from restricted airflow such as a dirty filter, closed registers, or a failing blower — it opens the circuit to shut off the burners and prevent heat-exchanger damage.

Trip temperature: 160°F
Type: Primary high-limit safety switch (auto-reset)
Function: Shuts down burners on heat-exchanger overheat
Fit: OEM replacement for Goodman/Amana AMH80703ANAA furnaces
Part number: B1370187

OEM vs. Generic: The primary limit governs whether the furnace can safely produce heat. The OEM B1370187 is set to Goodman's precise 160°F trip point and matches the original mounting flange and insertion depth. A generic switch with the wrong rating or geometry can cause short-cycling on limit or, worse, allow unsafe temperatures. OEM is the recommended choice.

Install difficulty: Easy (DIY-friendly). Cut power to the furnace, unplug the two spade terminals, remove the mounting screws, and install the replacement with the same orientation and probe depth. If the limit was tripping, replace the air filter and verify blower airflow before returning to service.
