The furnace does not fire up even though I installed new sensors( flame & Ignitor). The gas valve opens and I can hear the trigger switch sound ("click"), the furnace repeats this cycle four times and then stops. During the cycle, the red & green lights on the ignitor control board are blinking simustaneously, but after the cycle is over, these lights blink alternatively like twice per second.
How can I fix it?
Thanks,
Frank.
PS. The furnace uses natural gas.
