Browse high-quality oil control boards at F.W. Webb to find products that aid your heating system performance. Oil control boxes are in charge of input from various parts of the system. They monitor the thermostat, limit control, and aid in the startup and shutdown of the system. Browse our selection of oil burner controls and discover mechanisms to keep your system running smoothly, including kits and lockout alarms for added safety.
The main difference between gas and oil controls is in the design. An oil control system senses if a flame is present, using a cadmium sulfide (cad) cell device. A gas heating system control senses temperature to determine if a flame is present, and uses a mechanical switch to open and close valves to allow the electric current to flow.
You can tell if an oil control board is bad if you smell a burnt plastic/electronic smell, usually the result of a short-circuit. To verify, remove the access panel, inspect the control board, and check the diagnostic light. If the light is blinking or off, your control board could need repair or replacement.
