Blower problem
...just make sure you do a better job than Francis, OK?
I think your furnace is trying to surrender.
Habamus Papa!
Water getting into tank or cracked supply lines?
Flame sensor?
I had a gas furn that had the ‘would light then shut off problem’ it was a dirty flame sensor. The furn would light but the sensor would not recognize the flame so it would auto shut off
“White smoke” not steam?
Where is the white smoke coming out of?
Water....sounds like your original problem
Better than black smoke. That happened to us last year, also with a Beckett. We replaced it.
Call a professional furnace repair guy who actually knows something - else it could get very expensive very fast.
Sign a three year contract with a reputable AC/Heating firm to keep your system running smoothly.
But then you probably thought about that before you posted this bit of nonsense.
How’s your other appliances working? Can’t wait to hear about the next crisis.
Contaminated fuel would be my guess too.
Just like with a car white smoke may indicate water getting into the combustion.
Maybe a leaking recirculating water pipe inside the furnace...
It needs to be cleaned. The heat exchanger is choked up.
Do you have to push the reset each time after it turns off?
If so then I would be very suspicious that flue or chimney might be plugged or restricted. If it were then it would cause white smoke to build up in the fire chamber which would leak out the inspection door. It would also obstruct the view of the flame reaching the electric eye and cause it to shut down on safety.
Oil burners are usually very easy to diagnose in person if you know the symptoms. But everyone of those symptoms are important for proper diagnosis.
Does the flame light immediately after when the burner starts?
Does the flame look good in the first couple of seconds?
Furnaces help to destroy the planet, you know.
Hire a professional who knows what the heck they’re doing..........Furnaces are nothing to screw around with.
Here’s someone (from 2007) who appears to have had the same or similar problem. Go to the link to check the responses. I haven’t yet.
“Excuse me if I use the wrong terminology...but I have a fuel-oil furnace that white smoke appears through the burner after the burner shuts off and the blower is still running, after about 45 seconds...white smoke starts to come out of these small holes on the burner and fill the basement with white smoke and smell like fuel. ...”
What you describe may be what the fire service refers to as a “white ghost”...
Article from Fire Engineering on the subject of oil furnaces...
May help you diagnose possible problems...
Be careful...That white cloud is fuel/air mix and somewhere within lies the flammable range...Possible Ka-blooey situation!
