Carrier Limit Switches

A carrier limit switch is a crucial safety device in HVAC systems, including carrier furnaces. This switch monitors the temperature inside the furnace or air handler. When temperatures exceed safe operational limits, the limit switch automatically shuts down the heating system to prevent overheating and potential hazards like fires. It plays a vital role in protecting the furnace from damage due to overheating and ensuring safe operation. In essence, the carrier furnace limit switch acts as a guardian, preventing dangerous situations by interrupting the heating cycle if temperatures become too high. Regular maintenance and monitoring of this switch are essential for the efficient and safe functioning of Carrier furnaces, providing homeowners with peace of mind and reliable heating performance.
