Frequently Asked Questions

What is a Carrier rollout switch used for?

A Carrier rollout switch is a safety device that monitors burner flame rollout in gas-fired heating equipment. It shuts down the system if flames escape the combustion chamber, preventing fire hazards and equipment damage. It is commonly used in furnaces, boilers, and rooftop units.

What are the specifications of the Carrier HH18HZ195 rollout switch?

The Carrier HH18HZ195 is a rollout switch with manufacturer part number HH18HZ195. It is a replacement HVACR control switch designed for Carrier gas-fired heating systems. The switch trips when abnormal flame rollout is detected, interrupting the gas valve circuit for safety.

Where to buy a Carrier HH18HZ195 rollout switch worldwide?

You can source the Carrier HH18HZ195 rollout switch through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine Carrier replacement parts for HVAC systems.

How to install a Carrier rollout switch?

To install a Carrier rollout switch, first disconnect power and gas supply. Remove the old switch from its mounting bracket, noting wire connections. Connect the new HH18HZ195 switch wires to the same terminals, secure it in place, and restore power. Test for proper operation by cycling the furnace. Always follow the equipment manual.
