Goodman 1370906S High-Limit Switch (150°F)

The Goodman 1370906S is a genuine OEM high-limit safety switch engineered for the GUPI075-4 gas furnace and compatible Goodman/Amana heating models. Mounted on the heat exchanger or blower deck, this 7-inch limit switch monitors internal temperature and cuts the gas valve if the furnace exceeds its safe operating limit — protecting the heat exchanger and preventing overheating. A failed limit switch is a common cause of short-cycling, no-heat calls, and nuisance lockouts.

Specifications

Trip temperature: 150°F (auto-reset)
Probe length: 7 inches
Type: Normally-closed high-limit safety control
Fits: Goodman GUPI075-4 and cross-compatible furnaces
Terminals: 1/4-inch quick-connect spade

OEM vs. Generic

The OEM 1370906S matches the factory trip point and bracket exactly for a drop-in fit and full reliability. Our generic equivalent meets the same 150°F rating at a lower price and is an excellent value for out-of-warranty repairs where an exact factory match is not required.

Installation

Difficulty: Easy (DIY-friendly). Two mounting screws and two spade terminals — most technicians complete the swap in under 10 minutes. Always disconnect power at the furnace disconnect or breaker before servicing.

This is a safety-critical component. If your limit switch trips repeatedly, inspect for restricted airflow (dirty filter, closed dampers, or a failing blower) before replacing.
