The Goodman B1370190 Primary Limit Switch is a genuine OEM safety control designed for the AMS80453AXAA gas furnace. This normally-closed thermal switch opens the control circuit if the heat exchanger area exceeds its 210°F trip temperature, shutting down the burners to prevent overheating and protect the furnace. If your furnace short-cycles, trips on high limit, or fails to fire, a faulty limit switch is a common culprit.

Type: Primary (high) limit switch, auto-reset
Trip Point: 210°F
Action: Normally closed, opens on rise

OEM vs. Generic

Our OEM B1370190 is the exact factory-spec Goodman component, guaranteeing the correct trip temperature and mounting bracket for a drop-in fit. Our Generic equivalent meets the same 210°F rating at a lower price point and is an excellent choice for budget-conscious repairs where an aftermarket UL-listed part is acceptable.

Installation

Difficulty: Easy (1/5). Replacement typically takes 15–20 minutes with a nut driver. Always disconnect power at the breaker before servicing. Note wire positions, remove the two mounting screws, transfer the leads, and secure the new switch. A great DIY-friendly repair for handy homeowners and HVAC pros alike.
