My oil heater stop working and won't switch on when I hit the reset button. Less than a month ago I changed the oil filter and a technician came and change the therostat flame detector on the oil burner and also the boiler, so at this point I have no clue why it would stop working.

1. Do you have oil

2. is there power at the unit

3. if you not very furnace savie,call the man that knows something, you shouldn`t keep hitting the reset button you might break it.

Yes I do have oil

Yes there is power at the unit
