If you have oil-fired central heating, you need to be able to rely on it to burn, especially when winter comes. There are a number of common problems that may prevent welding thicker tabs from working or not firing. It's useful to find out what's wrong before calling your local heating engineer as they may be able to fix it for you over the phone.

What Shall I Do If My Oil Burner Won't Ignite?

Heavy oil burner

 

Thermostat

First check the clock settings and thermostat settings on the boiler and in your home. They may be set too low.

 

Furnace Heat Exchangers

Before making any repairs, you should make sure to thoroughly inspect your furnace heat exchanger. Take it out of the furnace and inspect it under a light. Look for signs of metal overheating, or symptoms of long-term metal fatigue. Check the cracks themselves. Look for signs of rust, and wipe the surface with a cloth if necessary.

 

Boiler power

Next check to make sure there is power coming through the boiler. Check that the heating clock is actually on and check that the system fuses and/or plugs are working properly, as well as any plug/switch connections on the boiler.

 

Burner trying to ignite

Do you have enough fuel? The first thing to do is to check the fuel level in the tank. The oil level should be above the tank fuel line feed point and the level will be constantly changing. You can use an external tank level gauge, but the older it is the more difficult it is to identify the actual level. If easily/safely accessible, the best and most accurate method is to remove the tank filler cap and look inside.

Clogging

Faulty oil pump, clogged filter, or faulty coil. Incorrectly set electrodes or a blockage in the nozzle hose can prevent the burner from igniting. Insufficient air flow to the burner can also prevent the burner from firing. An uncommon but possible cause could be a weak transformer or a faulty control box or capacitor. Incorrect wiring. Blocked oil circuit. Contaminated oil.

 

Cracks or Holes

If you find that your furnace heat exchanger is not getting enough heat and power, then you may find that it has developed a crack or hole. Through this crack, combustion fumes can escape from the exchanger and can build up in the room. To solve this problem, most people choose to replace the furnace heat exchanger rather than risk further corrosion.


You should add a carbon monoxide alarm to the space above your furnace. This will give you a clear warning if your furnace has a fume leak and protect you from possible toxins. Furnace heat exchangers are an important part of your furnace, so changing them may also void any warranty you have on your furnace.
