It's a Coleman-Evcon BGU10016A Forced Air Furnace.
Last year when they unit was acting up and I replace the blower motor,
it would start up. The red light was blinking several times
indicating a problem with the Pressure Switch. I knocked it a couple
of times and wa-la. It worked problem free until now. This is the
first time I'm asking the unit for heat in 7 months. Odly, the A/C
side of the unit will not work now. It just makes a low hum as though
the blower is trying to spool up but can't. I changed the capacitor
but no help. Thanks for the help.
