The gas valve controls the flow of gas to the furnace.
A malfunctioning gas valve usually necessitates complete replacement.
2.11. Limit Switch
The limit switch is a safety mechanism that prevents the furnace from overheating.
Limit switches typically fail only when the furnace is subjected to extreme overheating.
2.12. Pressure Switch
Another safety device, the pressure switch ensures proper venting of combustion gases.
Pressure switches typically fail only under extreme stress on the furnace.
2.13. Sequencer
In electric furnaces, the sequencer regulates the power draw, especially during startup, preventing breaker trips.
Sequencer issues are a common cause of electric furnace malfunctions.
2.14. Smart Valve
A smart valve is an advanced type of gas valve with its own integrated circuit board.
Smart valves were used in limited furnace models, making replacements potentially difficult to find.
2.15. Thermostat
The thermostat senses the temperature in your home and signals the HVAC system to activate.
Various thermostat options are available, ranging from basic models to advanced smart thermostats.
2.16. Transformer
The transformer supplies electricity to the furnace.
Transformers typically fail due to electrical shorts or surges.
