Oil furnaces require regular maintenance, however, there are occasions when oil furnace repair is the only solution.
It is important to understand how your oil furnace operates, because then you will be able to know better when an oil furnace service is required. Oil furnaces spray oil into a combustion chamber and then use an electric spark to ignite the oil which is sprayed in a continuous flow. The very fact that oil combustion takes place within the boiler chamber means that the boiler can reach very high temperatures. This is significant because high temperatures can cause wear and tear on components. Heating and cooling of these components causes stress on the boiler.
Fuel oil furnace repair is best carried out by a specialist oil boiler repair engineer using recommended oil furnace parts. Such parts can include filters, blowers, motor belts, switches and the thermostat. Parts such as the electrodes, oil nozzle, air tubes, transformer, pump and other components require an engineer with specialist tools and testing equipment in order to test, replace or both.
Your first port of call should be to read your boiler manual and familiarize yourself with basic maintenance and fuel oil furnace repair troubleshooting. Generally the first sign that you will have that there is something wrong with your boiler will perhaps be a continuous noise or knocking. This may be flagged up in your boiler manual. Oil heating repair may necessarily involve the services of a registered heating engineer in this case. Calling one in at the first sign of a problem will help to cut diagnose the problem quickly and reduce the potential for further damage if you do not attend to an issue.
Issues which can arise include:
The boiler will not start – this could be as a result of a burned out motor, whatever it’s cause you shouldn’t keep pressing the reset button as this loads more fuel into the burner.
The boiler is running but there is no fire – this may be indicative of a blocked nozzle.
The burner is running, there is fire in the furnace, but there is no heat being pumped around the system – in this instance check that the filter is not blocked, or that the fanbelt does not need replacing.
Good maintenance should include replacement of parts within the boiler on a regular if not annual basis. For example, the replacement of filters and perhaps motor belts will save you money in the longer term ensuring that the life of your boiler is extended and an oil boiler repair is not required. Your boiler may require a test of your thermostat to ensure it is working effectively and does not need re-calibrating, or it may require a more serious replacement of an oil nozzle or air tube within the boiler. Regardless of what oil furnace repairs you require, it is essential to carry out maintenance on a regular basis to prevent such faults from arising and also be ensure that you use a qualified engineer to carry out your oil furnace repair.
