Help...as noted in Title I am having problem with Amber LED only and can't get furnace to fire. Well over due for a cleaning I know that much. Ran low on oil just before start of Vacation last week, had oil delivery Monday while out of state. Family member checked on house mid week and Red LED on, 2 resets and furnace fired and stayed running to temp while they were there. 2 days later red light again. Assumed clogged filter and told them I'd deal with when I got home. Last night got home and multiple attempts failed with reset including clearing full latch up. This afternoon had emergency call to a tech and they came out, did same as I had done last night, including bleeding the line. They didn't have a matching filter, but did clean the Sensor. After cleaning sensor the furnace fired right up. worked good for 2 more oil calls and then I started having issues with only Amber LED flashing. If I disconnect one lead from the FF block on the controller then unit will call for oil. But don't want to leave disconnected.
Can I use this for a quick fix if I need to just get enough hot water for showers in the AM and not pay for another emergency call tonight? Also can I reconnect the lead while system is energized?

Please don’t do that!
Why should you have to pay for the tech to come out for the same problem you just paid to get corrected?
And call a competent qualified oil burner tech. A person who cleans the cad cell eye, doesn’t carry any standard oil filters cartridges on their truck, is not a professional.

This.

@vyyper23 , where are you located?

If you take one of the wires off the ff, and it runs, then the flame sensor has a short or is seeing light. But, the control should lock out in about 45 seconds with the wire off. If it keeps running with the wire disconnected, then there is something wrong with the control. Either way, you should not run it like this.

Repeated resets. Cleared from lockout and reset again. That is dangerous. Since the burner fires, theres oil going into the chamber every time you press the reset button. Whether it ignites or not. Shut the boiler off and get a competent tech to completely service and repair the system since it's well overdue as you said. Keep hitting the reset button and you wont need a tech, you'll need the fire department.

If that control has a 45-second trial for ignition, it no longer meets most Codes, and must be replaced with one having a 15-second TFI.

Ricks troubleshooting advice is correct. However, I just hate providing a homeowner or any inexperienced person with that type of information because someone will do stuff like that instead of paying for a proper repair.
Then one day, they jump it out, the burner doesn't light, flood the chamber with a gallon of oil. Try it again and it DOES light, and that's all she wrote.
