The Goodman B1370912S Primary Limit Switch is a genuine OEM high-temperature safety control for the GMPE100-4 gas furnace. Mounted on the heat exchanger area, this normally-closed switch opens at its trip temperature to shut off the burners if the furnace overheats — protecting the exchanger and preventing unsafe operation. A tripped or failed limit is a frequent cause of a furnace that runs then shuts down on a limit fault.

Part number: B1370912S
Trip temperature: 240°F
Insert length: 7 inch
Type: Primary high-limit switch (auto-reset)

OEM vs. Generic

The OEM Goodman limit is set to the exact 240°F trip point and 7-inch probe depth specified for this furnace. Because this is a safety component, an incorrect trip temperature or probe length can allow overheating or cause nuisance shutdowns. We strongly recommend the OEM part over a universal substitute for anything safety-related.

Install Difficulty

Easy to moderate (20 minutes). Power off, remove two mounting screws, disconnect the two spade terminals, and install the replacement with the same insert depth. No adjustment needed on this fixed-temperature switch. Always shut off power at the breaker before servicing.

Compatible with Goodman GMPE100-4. Verify your model and part number before ordering.
