when i turn on the thermostat the draft inducer comes on and 3 seconds later the blower comes on. the gas valve never opens and the blower and draft inducer wont shut off until you turn off the thermostat. previously i had to jump the limit switch in the blower compartment and it would fire. i tapped the limit litely a couple of times and it worked for 2 weeks. then it would not fire during the day but only at night. so i figured i needed to get a new limit switch. i now jump the limit and the blowers run and the gas valvle wont open and the board flashes 3 times.
