Description

This oil burner primary control is the safety device that senses ignition and allows the burner to run only when combustion is confirmed, helping prevent fuel flow without a stable flame. It replaces a failed primary control to restore normal burner operation. What it does:

• Acts as the main flame-sensing and safety interlock for oil burners to prevent unsafe operation
• Detects flame presence and permits the burner motor and fuel valve to stay energized
• Commonly used when the burner cycles to lockout, won't stay lit, or has intermittent ignition
• Helps stop continuous fuel flow during a no-flame condition, reducing fire/flood risk

What's included:

• One oil burner primary control

Install notes:

• High-voltage and fuel hazards — disconnect power and follow fuel shutoff procedures before servicing
• Replace with the exact control for your burner model; wire per OEM wiring diagram
• After installation, test burner operation and safety interlocks per manufacturer instructions
