After being refilled, your furnace may or may not restart on its own.If your furnace has a reset button, you can restart it with little effort.If the reset button doesn't work, you'll have to bleed the fuel line to restart the furnace.Problems like faulty lines or filters can be fixed if your furnace refuses to light.
Step 1: If necessary, put a container under the bleeder pipes.
Two copper lines should be running from your oil tank to the pump if your furnace has a reset function.The oil may bleed from a fixture if your pump doesn't have pipes.You might need to put a container underneath the fixture to catch the bleeding oil.
Step 2: The reset button needs to be pressed.
Some furnaces do not have a reset button.If you have this feature, you should find it on the furnace, close to the oil tank.The button is usually red.Push it a couple of times.If you can't locate the reset button on your furnace, consult its user instructions.This part should be clearly marked on diagrams.
Step 3: If the furnace doesn't light, check the fuses and breakers.
After pressing the reset, make sure the furnace comes on in 60 seconds.If necessary, replace or reset the fuses.If you can, try to reset the furnace.bleed the fuel line if the furnace does not relight.A lack of oil spray on the inside of the furnace is an indication that you need to bleed the fuel line.
Step 4: You need to gather your supplies.
Some of these supplies are already in your house.You can buy those at your local hardware store.To bleed your furnace, you'll need: 14 in (.64 cm) flexible tubing Container, oil absorbent material, and rag.
Step 5: Turn off the furnace.
There should be a switch on the furnace.The furnace should be turned off.Your furnace may have been turned off by the reset button.The reset button has a red "On" light next to it.You don't need to turn the main On/Off switch to "Off" when the auto-shut off is engaged.
Step 6: The bleeder valve needs to be located.
On the side of the fuel pump, this is usually positioned at 4 or 8 o'clock.The bleeder appears to be a grease fitting with a nut shape, like a 8 inch wrench.There are fuel lines leading to and from the fuel pump.On the left side of the burner unit is where the pump is located.
Step 7: Attach nylon tubing to the bleeder.
The container should be placed close to the bleeder.Attach the tubing over the bleeder.The bottom of the container is where the tubing should extend.The container will be used to catch the oil.It's better to choose an oversized container than an undersized one.A big mess can be caused by oil that overflows.If you have bleeding oil from the pump of your furnace, use a clean, dry container.After the oil is drained, you'll be able to return and use it.It can be difficult to drain the fuel line for your furnace.You might want to wear gloves while bleeding.
Step 8: Allow the bleeder to be loosened.
The bleeder should be loosened with a wrench after the tubing is attached.To do so, turn it clockwise.Re-tighten the bleeder when it's broken loose.You might hear a gurgling noise during this process.This is not artificial.
Step 9: The bleeder should be opened when the furnace is turned on.
From "Off" to "On", turn your furnace on.Immediately after that, open the bleeder valve.The oil and air should be ejected by the tubing.The force of oil and air can cause the tubing to move.It's a good idea to hold the tubing and container to prevent spills.The reset button can be used to turn on the furnace.Follow your furnace's instructions to get the best results.The bleeder valve can be opened more or less.It's necessary to adjust this for your situation.To get a good flow, the bleeder screw may have to be removed.Once the flow has begun, shut the furnace off.When the furnace is bleeding, replace the screw.
Step 10: If necessary, resolve locked out reset buttons.
A safety lock out feature may be preventing you from pressing it again if you hit your reset button multiple times.Press and hold on to the reset button for 35 seconds.
Step 11: Remove the line until the fuel comes out.
After a few seconds, the bleeder should start expelling oil.The line should be drained a few seconds after this to make sure the air has been removed.Turn the bleeder clockwise until firm.If the pump is far from the oil tank, you may need to bleed your line into your container several times until the air is removed from it.If there is no discharge from the bleeder, there may be a problem with the pump, filter or fuel line.After the fuel has been drained, it can be returned to the tank in a clean, dry container.
Step 12: The burner should be checked for ignition.
You should return the bleeder valve to its closed position.The furnace should be turned on.The furnace should light up at this point.The front of the furnace has an inspection port where you can see an orange glow or fire.If the furnace doesn't relight, drain the line again.You might have to bleed the line several times to get it to work again.
Step 13: Take a look at the oil supply lines.
It is possible that damaged or crushed tubing is starving your furnace of fuel.Oil may not reach the burner if the lines are leaking.Tubes should be replaced if they are rotten, leaking, or degraded.Most hardware stores and home centers have tubing for your furnace.The furnace should be turned off when you replace tubing.A big mess can be made when oil is left in tubing.You should put a newspaper, cloth, and container under the tubing to prevent a mess.
Step 14: The air was coming out of the oil filter.
If your furnace doesn't restart after bleeding the fuel line, you may need to remove the air from the filter.The oil filter can be found suspended near the fuel line.To bleed the oil filter, loosen the 4 inch bolt on the top of the filter with an appropriate wrench.Don't loosen when you hear air.The air should be let go.When oil begins to build up around the bolt, close it to the position you found it.
Step 15: If necessary, replace your oil filter.
Clogged filters can prevent the furnace from restarting.Most home supply stores have filters for your oil furnace.Different furnaces have different procedures.The user instructions for your furnace should be followed.Replacement kits usually come with new seals and bolts.For the best results, use the new parts.It's important to make sure the fastenings and fixture are snug when you reassemble your filter.
Step 16: If necessary, call a professional.
It's possible that the lines of your furnace are polluted.This may require a burner technician to clear the lines.You can find contact information for technicians certified to work on your furnace in its user instructions.
