Oil Furnace

If your oil burner stops running the first thing you should check is the reset button. Usually a red button located on top of the burner. If you press it and the burner fires up then that was the problem. If the button should trip again you should schedule a service call . Do not keep resetting the button. The button is part of a safety device. It shuts the burner down when it thinks there is a problem. It is on the primary control or cad cell relay. On a call for heat, with the burner running, the cad cell senses the light of the flame. If it stops sensing the light, it causes the red button to pop up, shutting down the burner before any significant damage is done.

Here is a partial list of causes and things to check. Most will require a service call and/or a cleaning.

• Bad or dirty cad cell
• Bad primary control
• Bad ignition transformer
• Bad burner motor
• Bad fuel pump
• Blocked oil filter or nozzle
• Air in oil line
• Burner running with a very high smoke level
• Burner sooted-up
• Out of oil
• Chimney blocked
