Carrier RC6800123 Limit Switch L150-60F

Description

Carrier RC6800123 Limit Switch L150-60F Overview

The Carrier RC6800123 is an OEM replacement high-limit safety switch designed to protect Carrier furnaces and heating equipment from dangerous overheating conditions. Designated L150-60F, this limit switch is engineered to open the control circuit at 150°F and automatically reset (close) after the heat exchanger cools to approximately 90°F — a 60°F differential — helping prevent nuisance lockouts while ensuring reliable overheat protection.

How It Works

Limit switches are critical safety devices in gas furnaces and air handlers. When supply air temperatures exceed the rated setpoint, the limit switch interrupts the burner circuit, shutting down the heat source before unsafe temperatures can damage the heat exchanger or pose a fire hazard. Once temperatures drop back within the safe operating range, the switch automatically resets and normal operation resumes.
