Most oil furnaces in use today are called pressure burners. In this type
of system, oil is sprayed into a combustion chamber at high pressure.
To become familiar with your oil furnace, remove the access panel covering the burner blower by removing the retaining screws around the rim of the housing. You can access the air blower and filter through a metal panel on one side of the furnace. The panel is held by either hooks or retaining bolts; slip the panel up and off the hooks or remove the bolts and lift the panel off. Most furnaces have switches and reset buttons located on the motor or in a switch box outside the furnace housing. These are usually identified with stampings or labels, such as DISCONNECT SWITCH, RESET, and so on. The stack control sensor, a safety device that monitors burner operation, is positioned in the stack and held with a series of retaining bolts.
There's not much you can do to fix an oil furnace, but routine maintenance can forestall many problems. On the next page you'll find a list of tips to keep your furnace running smoothly.
