Technician came in. He is here and said the control panel (motherboard) needs to be replaced and pressure switch (like I told him).
I don't understand if there is any reason to replace the board ? Could be burned by my jumper on switch like you told me ?
Fat pig wants to rip me off on $150 :/
Went back to supply warehouse to find exact model numer of the switch (have tried 2 different ones and still doesn't go on... )

I just went by the number of flashes you posted and the legend for your furnace. Jumping does not hurt circuit boards of components as long as it was done properly.
Sometimes other components/sections are defective besides what the flash indicates but not often.

Hi, sorry for a break with infos.
Technician just replaced my pressure switch, he changed some sensor which goes straight into the duct (two long legs and sensor on the end).
He also mentioned that chimney liner needs to be done. Probably I have furnace duct connected into brick chimney without liner inside. He said it may cause later problems with the furnace.

I figured it was the pressure switch but the sensor I had no idea. Better git the chimney fixed pronto. Good luck.

Could you tell me how much would cost installation of new furnace liner inside the chimney and connect it ?
Basement, first floor, second floor, roof.
About 25 feet.

I am sorry but I would not even want to guess, The material cost and labor is all set locally so the prices will be different all over the country. Sorry. Get at least 2 estimates.
