Carrier HH18HA160 Temp Switch 324846-701 Standardized Resistance: The 10K OhmThe Carrier HH18HA160 Temp Switch is a critical OEM limit switch designed for heavy duty thermal protection in commercial and residential HVAC systems. Engineered as a safety limit control, this genuine Carrier replacement part monitors the heat exchanger environment, automatically interrupting the burner circuit if temperatures exceed safe operating parameters. With a precise 160F cut out and a automatic 120F cut in reset, it prevents thermal stress
