I did have heat the entire time I had the problem with short cycling. The only time I personally hit the reset was after I changed the filter. Once I touched the filter I couldn't get the burner to run continuously.By then I knew oil flow was the problem. If this occurs again, I assume I can take my air hose to the oil line to blow it out. Right?
No, not right. If it happens again & probably if it does not, the lines & maybe the tank need replacing. That sludge is coming from somewhere, probably the tank.
you might have yourself an even bigger problem if you get your compressor and you use too much pressure --anyway if your tank is over 30 years indoors its time to clean it-have it tested, replace the valve,lines, pitch the tank--if underground that age its time to remove it
