Burner Won’t Kick on Below 66

We moved into this house in July and figured out that the burner won’t kick on if the thermostat drops below 66 degrees. We changed the thermostat and it is still happening. It will turn on if we hit the reset button.

    Unless the thermostat is a communicating device, the burner doesn't know what temp the thermostat is set to. More than likely the burner is locking out, and you are seeing a low thermostat temp as a symptom of the problem. To help you we need to know first and foremost what type of heating system you have, there are many burners in this world. We need to know, is this a boiler or furnace? what type of fuel? model of the boiler/furnace, if it is an external burner what model is the burner? what thermostat do you have?

    Hitting the reset button on the burner means there's a safety issue with the burner.
    If you're not familiar with oil, it needs to be serviced, or at least combustion tested annually. Ask around. Get reviews in your area for reputable oil service companies, and call. Because it's not DIY. Where are you located?
    And repeatedly hitting the reset button usually doesn't turn out good for anyone.
