this is an open fuse link

Standardized Resistance: The 10K Ohm Type II NTC thermistor ensures compatibility with major controllers like Johnson Controls and Honeywell

Stable Combustion: Multi-port design delivers a uniform flame pattern to prevent hotspots and maximize heat exchanger efficiency

Low) to manage airflow velocity across the coil

Coil the excess tubing carefully away from any electrical terminals or moving parts to avoid vibration damage or refrigerant leaks within the sensor bulb system

Carrier HH18HA160 Temp Switch 324846-701 this is an open fuseThe 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
