I have a 20yr american standard oil furnace I have been noticing on bad windy days it shut off?

On a daily basis it's okay but during winter stormy days or other times where we get windy weather conditions the burner goes off and i need to reset a few times. I do routine maintenance on the system since it's used year run because it supplies us the hot water too. I'm not too familiar with the working of the furnace and was just curious to know if this was a normal reaction or do i need to get a contractor? Any suggestions would be appreciated. Thanks|||If it's only a problem on windy days I'd suspect you're getting a wind-induced downdraft. Some sort of chimney cap might be in order.





If this is a new problem, then there may also be a contributing factor: the chimney needs cleaning or the burner needs adjusting.|||I had much the same problem on windy days the unit would cycle and fail to light. The problem was solved with a guard to prevent the wind from blowing in the wrong vent during the windy days. Modern furnaces have air pressure sensors that compare the intake and exhaust pressures and if they are not correct, the furnace will not operate. My furnace has the 2 vents about 3 ' apart and they are 2" PVC so the solution was a "T" on them to prevent the wind blowing in the furnace. Have a service done on your furnace and get a wind cap installed, the correct air flow is critical.|||it sounds like your furnace is ok - and usually older ones are way more reliable for alot of years - i would say it is just a wind problem - you can compensate 2 ways - install a wind gaurd at the bottom of wind sourse - also the down draft - comming down the fluke may be to blame - so other then that should be ok
