Welcome Polley! If you haven't already done so, I suggest you post this on the "Discussions" side of the Kitchens Forum. This is the "Gallery" where people usually post threads for the Finished Kitchen Blog or similar, usually not for discussions. The Discussions side is also much busier! Here is a link that might be useful: Read Me If You're New To GW Kitchens!

Paulbm has it right: There are two separate issues here: 1. That the furnace is using all of the combustion air for combustion -meaning that it is pulling the air into the furnace and then sending it out the flue. 2. The furnace has a problem with missing air return - so it's pulling the air from the closet, heating it, and sending it out to the rooms. 3. Both things are happening All of these situations are serious and are an indication that the job wasn't done by a qualified installer. The fact that it sucks the door closed indicates that it's probably at least #2 The closet must provide combustion air intake by having vents of at least a specific size that are a combination of requirements by the furnace and water heater manufacturer. Alternately, you can provide outside air intake for the furnace through a pipe - also spec'd by the furnace manufacturer. (you would still need venting for the water heater). You may not have a disconnected air return on the furnace. That is very dangerous in that it will draw carbon monoxide from the water heater flue into the house. In a way, you are fortunate that the water heater is being blown out. Far worse would be for the water heater to stay going and kill you while you sleep. Get this problem resolved immediately. Also get a Carbon Monoxide detector. Carbon monoxide is colorless and odorless. It's possible that this problem was a legitimate error... but not likely. I would be very suspicious of the person who did the install. What was done here can kill you and your family.

This is caused by a bad logic board. The logic board is the number you gave as the model number. The model number should be found on the opposite end of the opener. But anyway this is a pretty expensive repair and I think by that part number you have an old opener. Might start thinking about a new one but in the meantime you can remove the bulb.

Park-Vue makes a beautiful French Door that is aluminum clad on the exterior. They are made in Wisconsin and patio doors is all they do. A great value and very affordable. Michael Here is a link that might be useful: Swinging Doors
