A furnace panel is a component of a furnace system that houses the electrical and mechanical components of the furnace. It is typically made of metal and is located near the furnace itself. The panel typically contains a circuit breaker, which is used to protect the furnace from overloading and potential damage. It also contains a fan switch, which is used to control the speed of the fan. The panel also contains a thermostat, which is used to regulate the temperature of the furnace. Additionally, the panel contains a limit switch, which is used to shut off the furnace if it reaches a certain temperature. The furnace panel is an important part of the furnace system and should be inspected regularly to ensure that it is functioning properly.
