    York residential furnace pressure switch problem code stuck switch
    I have a york furnace P2MD12H06401A after 1 hour it shuts down and gives a 2 flash error for a stuck pressure switch. The switch is new can it be wired wrong? The old one had 2 white wires piggy back and 1 blue wire. The new switch has 3 separate terminals

    Tap the pressure switch with the back of a skrewdriver. Sometimes that will get it to work. It may be that you have a faulty switch... I have had mine replaced once already and my unit is only 4 yrs. Old. I would replace it with a universal switch as opposed to a Coleman. It's much cheaper and probably will work better.
