    we recently replaced the guns & cleaned all inside. it was runnig perfectly for a month , then it started to shut off during the night, especially if we turned down the heat. We could go out & hit the reset, furnace would run for a couple of days then shut off again so we replaced the unit on the burner. we tried to hook up as well as we could since the color coding of the wires are not the same. we need a diagram to see what is not hooked up correctly, getting codes of 9999 . Does anyone have any ideas? Thank you for your help. was just laid off due to covid 19 shut downs 7 cant afford anything till the unemployment system is fixed in oregon

    You really need to be careful with this.

    Your problem may be the control or it may not be the control.

    Oil burners need to be adjusted with combustion test instruments.

    Safety controls need checking for proper operation.

    There is a reason most states license oil burner technicians.

    Everyone is in a spot because of the "Bat Flue"

    Be careful with this

    I would like to add that it is very important to make proper adjustments to your oil burner so the flame burns safely, Clean and efficient. this video will explain the process.



    I do not recommend anyone but an experienced technician perform this adjustment, or for the experienced technician do this without proper test equipment. That being said, we have no control over homeowners doing DYI repairs. Many times you get almost there and the system operates, but over time the poorly adjusted oil burner will have a buildup of carbon or soot on the heat exchanger. The internal burner parts may also "coke-up" because the nozzle and electrodes may not be properly adjusted.

    Many of the homeowners perceived problems associated with a "thermostat not working" have nothing the do with a thermostat. When the control that is connected to the thermostat is defective, the thermostat is fine... but it does not work. Also, the oil burner that the control is connected to may not be adjusted properly, so the thermostat and the control are fine and doing the proper job. the burner adjustment is the problem. I could go on forever with "what is connected to what"

    But getting back to your issue: No money during Pandemic. There are some things to look at. #1 the flame sensor may be dirty. This is a small black plastic cylinder about 9/16" diameter with 2 yellow wires leading to the control. It is usually located under the top cover that has 2 hex head screws holding it down. The 2 Philips screws closer to you are not removed, they are holding down a hinge. be sure the electric to the furnace e is turned off. The flame sensor end opposite the wires has a glass cover over the sensor. If that is covered with carbon, the light of the flame can not get thru to the sensor on the other side of the glass.

    if this is the problem, clean the lens of the sensor. Also you need to determine the reason the lens got so dirty within a month. if there is a lot of soot inside the heat exchangers, you need to remove the soot with a Soot Vac. the normal shop vac will work but you need to check the filter often to make sure you don't force soot out the exhaust of the shop vac into the home. If you can... put a hose on the exhaust and run the hose outside. This will make the L7284 trip by the safety circuit.

    Once you get the heat exchanger clean and all the access doors and smoke pipe fro the heater to the chimney, you need to determine why the burner is making soot. Maybe not enough air. if you do make any adjustments be sure to have a pro come and check the adjustment as soon as possible. I do not recommend that you do this, but if you do you must take care and review as many of the YouTube videos on the subject of adjusting oil burners as you can. By doing this you can be making a small problem turn into a big problem.

    Since we are near the end of the heating season, it might be a better idea to put a few extra blankets on and wait for the time you can afford a burner pro.
