Check the venting for a restriction, check the condensate hose for blockage, check the pressure switch and hoses going to it. And make sure the small exhaust fan spins freely.

Check the fuse on the board. It is a 3a automotive fuse. There may be a problem in the control wiring. If the fuse is blown, make sure to find the reason why it blew and repair it. Otherwise you will need a whole bunch of fuses.

colman uses the furnace to power the attic vent fan . Cheaper that way I guess. It just supplies your attic fan with power so it will vent thus keeping your home a little cooler in the summer.
not a big deal. you can shut the alarm with a switch ot cut power to the alarm.

The error code refers to a defective combustion air switch. Coleman Evcons made around 2007 had defective pressure switches or as they call them "combustion air switch". Replace it and the problem is gone.

Pressure switch error code, Check the air filter for blockage, check the vent pipes for blockage or water, make sure the condensate drains are working and that there is no water in the hose(s) that go to the pressure switch(s).
