Question about Kitchen Appliances - Others
I try to turn on my furnace and i get a flashing code
furnace wont turn on / pressure switch stuck open what should i do
Check the intake and exhaust plumbing for any obstructions. I had same issue, turned out to be ice in the air intake plumbing on outside of house. This may be the problem. The pressure switch can be tested by pulling hose from purge motor that goes to switch and applying a small amount of suction. The switch should make a clicking sound.
