I bought a used mobile home in May 2005.The air forced oil heater was serviced April 1 and 4 with a pump, electrobes and filter. The tank was filled Nov. 5,2005. It was bleed. It ran for 12 hours and quit. A new thermostat was installed. It clicks on pumps fuel and the button kicks off. It is not heating or blowing. Manually you can hit the blower and it works. What should I do. Never had this set up before. Not sure why it ran fine for 12 hours then quit.
