I have an oil fired aga the oil will not come throw to the burner


see the following steps:
f the burner doesn't run, set the thermostat a few degrees higher than normal to see if it comes on. If it still doesn't come on, check switches, and breakers and fuses (see the Electrical Service Panel Fix-It Guide). If the unit has a reset button, press it. Also oil the motor at any oil ports (see below). If the unit doesn't want to start and run, first check the c to make sure that the ignition is getting power. If there is power, check the built-in safety controls (see below) that may turn the system off if they perceive problems.
If the burner cycles too often, replace the filter (see below). Also, oil and adjust the blower (see the Forced-Air Distribution Fix-It Guide).
If the burner runs but won't fire, make sure the oil valves are open and that there's oil in the tank. Check the tank level with a clean stick.
If the burner smokes or squeals, shut off the unit, let it cool, and fill the oil cups. Recheck them after the motor has run for an hour.
If the chimney smokes even after the flue has warmed up, the unit is wasting fuel; call for professional repair.
Safety Controls
Oil furnaces and other heat systems include safety devices that monitor operation and turn off the unit if something goes wrong. In some cases, the safety device can be the problem.
If you encounter an operating problem with an oil furnace, first reset the safety and try again.
If the burner kicks off again, shut off all power at the electrical service panel ; the burner motor and ignition may be protected by separate fuses or breakers.
If the sensor has a photocell, wipe it with a clean rag or tissue and see if the furnace starts.
If the safety is a stack switch mounted on the flue, remove the screw holding the unit to the stack, slide it out, and wipe off the sensor.
If the furnace won't start after three tries, seek professional assistance. Unburned oil can accumulate in the combustion chamber and "flash back."

Our furnace seems to run on idle constantly . we are using more oil but not electric if i tap on the box it stops but starts again a few minutes later??


We need to get a few details cleared up:

Is it the Furnace (Oil burner) that is running, (on idle you called it..)
or is it the FAN that is running?
What are you tapping, that shuts off what?
Is the fan that blows the air around the home shutting off, or the burner?
(When the burner is running, there is a loud roar!-- the fan should be much quieter..)

If it is the fan that is running,-- I might ask, is the air coming from the registers too cold?-- for with the fan running, you are getting all the heat from the oil that was burned. But naturally, you don't want it to be uncomfortable.. So-- you can open the cover on that Fan control switch, and raise the temperature at which the fan turns ON and OFF..

Let us know what you find.

What are the correct setting on the limit switch for oil furnance? My fan comes on off and back on within 1 minute.


The correct setting is whatever setting you want. Set the fan on at some temperature, set the fan off temperature at about 20 degrees below the on setting. If it still runs a short time, either increase the on time or decrease the off time. If the off temperature is comfortable to you then I would suggest increasing the on temp. Do the changes in small steps. Good luck and keep that oil burner tuned...

I have an olsen oil furnace, the problem is the burner will shut down 5 or 6 times before it reaches the set temp, the fan limit control is set at 90 and 120, its a honeywell limit control.


Hello A couple of things.If burner is cycling on high limit ,it can be a air flow problem.Change the air filter.Check the blower wheel that is reasonbaly clear/clean.Also check the intake grille that it is not blocked and all the supply grilles are open.Also mabey the nozzle size can be steped down if the input is too high(a slightly smaller fire).If the blower fan on/off is the problem (as the burner is seperate) raise the 120*f pin to 130*f but hold the wheel disc steady during adjustment.Leave the 90*f at 90*f.

I have a vulcan silhouette manual wall furnace that gets really hot and the grill and vents are starting to warp the thermostat doesnt seem to be working, should i still be using the heater...


YOU MUST HAVE THIS THING CHECKED OUT BY AN EXPERT. IT IS A FIRE HAZARD. Even if the thermostat was a closed circuit, the furnace would be working all of the time but it would not be overheating to the point of warping parts. You are either overfiring or your blower is not running all of the time. If it's a blower problem, clean out the dirt and dust and oil the motor. If the motor is not running, replace the fan control or the motor. If the furnace is overheating, your gas regulator might be bad allowing to much gas pressure to the furnace. Also, make sure that the burner orifice's are the correct size for the heater.

The fan runs whether the thermostat is turned on or off. If the thermostat is on, the burners fire up. The only way to get the fan to stop is to inplug the furnace.


Chances are you ahve a bad fan limit switch. If it is adjustable try to adjust. Set at 90 and 120. If it is off a little move the temp up a little. Should have slide dial under the lid on the fan limit. Keep in touch Rus

HOW DO I PURGE AIR FROM FUEL LINE SO MY BURNER WILL START I ALREADY BLED THE BURNER BUT AM STILL GETTING AIR OUT THE LINE


You will need a coffee can, clear hose that fits snugly over the bleeder screw and a 3/8 or 7/16 open end wrench. Find the bleeder screw on the oil pump. It will look like a grease fitting or brake line bleeder screw. Put the clear hose on and put the open end in the coffee can. Start the burner by making sure the door switch is closed and the red reset button is depressed. As the furnace starts, open the bleeder screw and watch the pink fuel as it goes into the can. Your primary control will trip after a few seconds (15-45). Close the bleeder. Reset the primary control, you may need to let the control sit for a minute or you may need to hold the button down for a minute to reset the control (each control is different). Then start the furnace and open the bleeder. You are looking for a good flow of oil with no bubbles. If you do this more than 3 times, you have an air leak in the suction line somewhere or low oil level.
