Phil :

Hi,This is risky business, not responsible for damages on your end. We *keep going until *you are happy. I come and go. be patient

Phil :

Tell me what brand and how old it is.

Phil :

tell me what color the main burner flame is when its running, Dark yellow is not good, a light blue or light yellow transparent flame is ideal.

Phil :

Tell me what brand and model number the oil burner is/

Customer:

not sure of the brand...its about 15 years old

Phil :

We can go from there. Im in and out, this evening, if you miss me, I will be back in the AM, just post a full response and I will pick it up on rounds tomorrow. we go until your situation is resolved. Phil

Phil :

remove the front panel of the boiler to find the burner,

Customer:

ok thats already done

Customer:

the furnace is running as we speak...but over the last 2 days i've had to hit the reset button about 5 times

Phil :

Look for the burner/ oil pump/ blower assembly.. it produces the flame. it will have a name plate attached, tell me what the brand and model number is

Phil :

Probable cause the problem is a dirty flame sensor rod or soot on the infra red flame sensing 'eye'

Phil :

Both easy fixes... scroll the screen up to see all of my messages to you,

Customer:

ok..let me go and get the brand and model number for u

Customer:

its a Oneida Royal Furnace LOR125A4B serial #964443 with a Beckett Burner

Phil :

Thanks, its a Becket burner.. now if you give the model number off the same tag I can look it up and see if it has flame sensor ROD. or an infra red flame sensing eye.. in their case they need to be cleaned off.

Phil :

that would step one of our work, If that fails we need to look into other potential causes

Phil :

I still need to know what color the main burner flame is

Phil :

Phil

Customer:

i believe the serial # XXXXX the burner is 980501-39511 its hard to read.......the flame is a light blue and yellow

Phil :

Hello again, the flame is perfect in that case. regarding the serial number.. we can't use that. the burner is traced by its MODEL number, that is stamped directly above the serial number in most cases.

Phil :

If you cant find the MODEL number, do this... look inside at the flame and see if you can see a metal rod poking into the flame...thats a flame detection rod. Sand it off with sand paper, that will most likely fix the problem

Phil :

If you don't a flame detection rod, it has an infra red sensor, a dime size lens, on the burner that detects flame, clean that off with whatever solvent you have on hand that works.. wait half an hour, then turn the unit back on.

Phil :

Let me know, we can go from there, Phil

Customer:

is the infra red sensor attached to the underside of the transformer ?

Phil :

Generally not, it is places so that it can 'see' the flame, and is much closer to the burner head area than the transformer which cannot be allowed get hot.

Phil :

If you can get me the MODEL number I can tell you exactly.

Phil :

Stay in touch, we go until all this is resolved. Phil

Phil :

the business end of the infra red sensor is dime sized glass lens.

Customer:

says its a Model "A", "AF"

Phil :

Look this page over and tell me if either of these is what you have.

Customer:

Looks like I have the AF model

Phil :

Go to this link, the complete flame detection kit is three items down on the page,

Phil :

Tell me you have anything like that,

Phil :

We can go from there, Phil

Customer:

i cleaned off the sensor and it appears to be working fine...thanks for your help
