I have read many posts on the subject of short cycling but have not found one that addresses my issue. I have a Goodman oil fired hot air furnace with a beckett burner. It began short cycling after being serviced by a local HVAC company. I have called that company back 2x and they have not resolved the issue. A separate company was also not able to solve it. I set back the t-stat at night and then raise it in the morning. If the new setting is more than 3-4 degrees, the burner will shut off before satisfying the tstat. The blower will continue to run and the burner will come back on after the high limit switch has cooled. At times the restart of the burner creates a loud boom and has blown off the stack vent, blew apart an elbow and blew out the barometric damper. I have raised the high limit setting, replaced the filters, and had the furnace serviced but this issue still continues on an infrequent, but troubling, basis. The nozzle is the proper size and the smallest recommended. Any suggestions.

It's difficult to say what the issue might be, particularly since you've already had professionals look at your furnace. You may have to get a second (or third) opinion from another qualified technician. If you do, make sure to have them inspect the thermostats as well as the ductwork, and not just the furnace unit itself. Any of these could contribute to the issues. Others have noted that booming sounds often signal fuel combustion issues. Unfortunately we can't offer more specific advice. Best of luck with resolving your furnace's troubles.

A smart thermostat may have a function to sense movement in a room. If something is covering the thermostat the furnace will short cycle.

I did to no avail. Filter was clean as a whistle.

Hi Sony, some thermostats are battery-powered, and can suffer from frequent restarting issues when the batteries get old. That could be the issue. If it's not the case, you might have to consult the manufacturer's troubleshooting guide for your model specifically.
