Description
The Carrier HH12ZZ165 is a limit switch, a safety device used in different Carrier HVAC products such as furnaces and air conditioners. it works as an automatic on-off switch depending on the temperature of the system. The switch works in such a way that when the temperature goes high, a certain limit is reached, it responds to protect the system, it interrupts the electrical circuit when the temperatures go high to the maximum limit of 165°F. the switch will complete the circuit when temperatures are low, for instance, at 40°F, this may be due to refrigerant leak or a faulty system component. The Carrier limit switch helps to control temperature variations and protect your HVAC system from high or low temperatures.
