Have a 6 yr old comfortmaker furnace, model number: N9MP2100F14C1. Code says problem with pressure switch. LED light blinks 3 times. Sometimes furnace works fine, other times tries to start up but won’t “kick in”. See some improvement when we take panel off, so just put panel back on now but did not tighten with screws. So far, so good. Any thoughts?

We have a relatively new furnace/ refrigerated air conditioning unit. I am concerned because no water is being drained from the air conditioner. Is this because we are experiencing days with very low humidity?? Your help will be greatly appreciated.
