Oil boilers are generally very reliable. When problems arise it’s usually the result of a lack of maintenance, a misconfiguration, or a unit that is reaching the end of its lifespan. Here are some common oil boiler problems and solutions.
1. The Burner Is Not Operating
There are several reasons the burner may not operate, they include a lack of fuel, a thermostat that is set too low or no electrical power to the unit. If there is sufficient fuel, check for a blown fuse or tripped circuit. Next, turn the thermostat up higher by a few degrees. Check that the filter and ductwork are not blocked or restricted and that the blower motor is operating.
2. The Burner Will Not Fire
If the burner is working, but will not fire, it could be a fuel supply problem. This can be caused by a failed oil pump or a clogged nozzle filter or oil line.
3. Smoking Burner
Smoking burners are often caused by an out of adjustment burner, a dirty or wrong type of nozzle or end cone. Other causes include a defective heat exchanger, incorrect oil pressure or an obstructed chimney.
4. High Fuel Consumption
When an oil boiler is consuming too much fuel it if often because off lack of maintenance or a system that is out of adjustment. An improperly sized or adjusted boiler can also cause inefficient operation and high fuel consumption.
5. Heating System Odors
Many of the same problems that can lead to a smoking boiler can cause odors, including a clogged nozzle, broken heat exchanger or a burner that is out of adjustment. The chimney may also need to be cleaned.
