The basement flooded. We cleaned the entire furnace and reassembled. The ac has been working fine. All summer. When I tried the furnace this morning. It flashed 4. I cleaned the connections and tried it again. Now it flashed 2. Meaning the pressure switch. My manual doesnt show where the pressure switch is located. Or a picture of it. The furnace is from 2006. When the backup started I immeduately tripped the breaker before it took on water. We managed to get the control board out as well before water contaminated it. I just wanted to check it before the heating season. If I cannot get to fire and work properly? I will call the company that installed the unit. I only wish to keep the costs as low as possible. If I can get it running. I will still call them for a seasonal cleaning. I have always cleaned it myself. Money is a problem. I am on disability. The furnace was completely submerged at one point. I figured that we would have some kind of problem. The ac took right off. And has been working well for the 3 months since the event happened

The pressure switch is a saftey for your protection,meaning rarely is the switch bad but and indication of something else wrong, usually blockage.I would strongly advise a professional to repair.
