Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
I have an Beckett oil furnace and a digital thermostat. When the temp in the house drops below the temp set on thermostat, the thermostat send a signal to the furnace but the furnace does not start. When I press the restart button on the furnace it starts, heats the home to the set temp and then shuts down but it won't restart once the temp in the house drops again. What could be the problem?
Bad primary control (the box with the reset button), maybe your thermostat but unlikely. Try the Primary Control first. How old is your burner?

By restart button you mean reset i believe,its located on top of oil burner and says only push one time .if thats the button your pushing it is the reset button or retry for oil burner if you are pushing this there is a problem with burner
