Troubleshooting your own waste oil furnace is a great way for you to be able to save money. Waste oil furnace repair can cost hundreds of dollars. Most of the time, you will find that fixing the furnace is safe to do. You will simply need to know what to look for and what to do when you find it. Many people have found that waste oil furnaces, resourceful as they are, can sometimes run into some issues with how they work. Luckily, you will find that a lot of the problems with your furnace can be easily solved.
If your waste oil furnace does not happen to start then you will first need to look to the thermostat for problems. Make sure that the thermostat has its set point above room temperature and that it is actually on heat. From there, you will need to try turning the fan to on from auto to see how it does.
Fan Not On
If the fan refuses to turn on then you may want to look at the fuse or the breaker for your waste oil furnace. If the breaker happens to have a blown or tripped fuse then you should look to see if the wiring has any issues. If it does not then you will be able to reset your breaker. If there is then you should call a professional for help.
If your breaker was not blown or tripped then you may want to look to the thermostat blower motor, run capacitor or the fan timer control. Once the blower has begun to run you will be able to get your fan put back in automatic mode on your thermostat.
Running Blower Burner Off
If you find that the burner is not on but the blower is running then this could potentially be a very easy fix. Simply go to the primary control and check to see if the reset button needs pressing. If it is sticking up then you will simply need to press down and then release it.
If you happen to notice that your burner is still not starting for you, then you will simply need to feel the side of your furnace. If it is warm then check your air filter. If the filter is clean then you may have a problem with your limit control. If your furnace is cool to the touch then you will need to check on the burner motor, primary control or the cad cell. Check your burner motor for a reset button. Not all waste oil furnaces have them.
Burner Motor not Staying on
A waste oil furnace may have problems with the burner motor stopping and having to be reset through the primary control. If this is the case then you may need to make sure that there is fuel in your tank. Also look to see if the nozzle on the fuel filter is not clogged.
No Sparking Sound
Whenever you turn the burner on there should be a sparking sound. If there is no sound then check your primary control or the ignition transformer as they could be bad.
