Carlin Hot water heater keeps going on and off.
Carlin Hot water heater, Model EZ-1 Has been acting up recently since last oil delivery. I did not go dry, Regular scheduled delivery. The Water heater unit keeps putting me into lock out mode. I bleed the system and reset it, it'll start back up with a green blinking light. The light hasn't gone solid green. But it works for a few hours and then shuts down and puts itself back into lock out mode. When it works, there are no lights. I can't figure this out. It's getting extremely
annoying to have to keep restarting it every few house. Any ideas?

I'm my own tech lol. It was fully replaced with a brand new unit in 2021

Those numbers are found using the combustion analyzer that your Tech should have used on the most recent service. If your Tech does not have one of these Combustion Analyzer things along with a Smoke tester for oil heating work, then I would fire him and hire someone that knows how oil burners actually work.
There are several reasons for a primary control to go off by the safety lockout. …and did you know that you are only supposed to RESET ONLY ONCE. That is taught in every technical school when the students are learning about oil heat primary controls. I'm just saying that it sounds like your Tech does not subscribe to that well known rule of the trade. If the control locks out after you have reset it once, then the knowledgeable tech would take the burner apart and find the cause.
- Partially plugged oil filter
- Partially plugged fuel pump screen
- Partially plugged nozzle
- Dirty ignitors
- Ignitors out of adjustment
- Ignitor insulators cracked
- Ignition transformer or electronic ignition failing intermittently
- Incorrect combustion air adjustment
- Incorrect fuel pressure
- Partially plugged fuel line from the tank.
These are just the first 10 reasons that a technician with over 40 years experience might think of off the top of his head. There are many more reasons. Maybe these reasons will help to refresh your technician’s memory about what might be the reason for the flame failure lockout!
But don't be too harsh on your technician, everyone needs to start somewhere!

After you make that expensive repair and you still have the same problem, What will you check next?

I'm not making up this "RESET ONLY ONCE" thing…. many different manufacturers of primary controls place these instructions in the literature that comes with the control and some even print it on the control itself

You find it on your combustion analyzer. Its DIY, until its not. Find an oil burner tech.

Oil appliances are not like refrigerators, toasters or vacuum cleaners. You don't just plug them in and expect them to work.
They need to be cleaned every few years and tuned and adjusted like a car they need professional attention.

You are your "own tech" until you can't fix it. Then you need a real tech. who has an experienced diagnostic approach to the issue.
