• Flame Sensor: The flame sensor is a safety device that confirms the presence of a stable flame.

• Gas Valve: The gas valve precisely controls the flow of natural gas or propane to the burner.

The Startup Sequence

Upon a call for heat, the control board initiates the ignition sequence. The draft inducer motor activates, creating a negative pressure in the combustion chamber. Once the pressure switch confirms adequate draft, the igniter energizes, heating up to a specific temperature. The gas valve then opens, releasing gas into the combustion chamber where it ignites upon contact with the hot igniter. The flame sensor then detects the flame, signaling to the control board that the main burner is successfully lit and the ignition sequence can cease.

If the flame sensor doesn't detect a flame within a specific timeframe, the control board will shut off the gas valve. This prevents a dangerous accumulation of unburnt gas. This is a crucial safety feature.

The Draft Inducer Motor (Inducer Fan): Ensuring Safe Exhaust

The draft inducer motor, often called the inducer fan, plays a vital role in safely venting exhaust gases from the furnace. It creates a negative pressure in the combustion chamber, drawing combustion byproducts through the venting system and safely expelling them outside the home.

This process is essential for preventing dangerous gases like carbon monoxide from entering the living space. The inducer motor must operate correctly for efficient combustion and safe furnace operation.

Safety Mechanisms: Pressure Switch and High Limit Switch

York furnaces incorporate several safety mechanisms to protect against malfunctions and ensure safe operation. Two critical components are the pressure switch and the high limit switch.

Protecting Against Unsafe Conditions
