What it does:

The solenoid valve is wired in parallel with the burner motor. When power to the burner is interrupted, the valve immediately closes, stopping fuel flow to the nozzle. This positive fuel shut-off helps improve burner performance and keeps the combustion chamber cleaner. 

Why it matters:

A faulty solenoid valve can cause:

• Smoky shutdowns

• Fuel nozzle after-drip

• Soot and carbon buildup

Replacing the solenoid valve restores positive fuel shutoff, improves combustion efficiency, and helps extend the life of your burner components.
