We are trying to clean the filter on our Carrier Weather Maker 8000 horizontal furnace. The instruction book diagrams are very poor and marginally look like our furnace. By removing the blower door we see a filter in the middle of what should be the return box however it is not in a V configuration as shown in the manual and is not removable thru the door. The rest of the box exterior is sealed with heat tape with no apparent way in. any advice?

Re: can't find FURNACE filter
First you have to get the old filter/s out. If not it will cause big problems in a short time. Use a coat hanger to grab the filter if you cant reach it. When you remove the old filter you will probably see how to install new ones. I think more than one filter is required for this furnace. Note the sizes of the old filters and buy the same replacements.
Don't worry about cutting some tape if needed. You can get another roll at any hardware supply. If all else fails, measure the interior of the return box and buy the right size filters. Remember, you must remove the existing filters!

The filter should slide out of a built in rack from the side of the furnace by the return inlet. It should have the size on it or you'll have to measure it. It may also be inside the bottom door. Pull the door up and out, the filter will be on one side or the other. Unless you have a special Hepa or electronic filtering system.
You can find what the error code is by looking on the inside of the bloewr panel. If it is still there after all these years there is a code list right around the wiring diagram. If my memory serves me correctly it is a limit problem. But be for sure and check the code sheet.
Hi and welcome to Fixya. I believe that the wind is affecting the draft. What I would recommend is to install a cap on the flue that is similar to a weather vane in that it rotates to block the wind from creating a downdraft in the flue. Some times depending on the direction and strength of the wind it will come up over the roof peak and then down the flue. A regular fixed cap may work too. You should be able to purchase one at your local hardware store. Please let me know if this was helpful. Good luck.
either the gas valve is not opening or your not getting gas to the furnace. also the gas valve won't open unless the draft motor comes on. if the ignitor is trying to light, but there's no gas, it might be a bad gas valve. i would call your closest NATE certified contractor
. Several times of recyling power normally brings the furnance up. Though the failure code has always been 31, there are several different behaviour when the blower starts after reset : a. blower simply creases. b. there is an attempt to start the heating unit (I hear the high pitch noises), then everything stops. c. there is an attempt to start the heating unit (I hear the high pitch noises), once I see the orange glow from the coil, normally the gas is lit up and the unit starts working.
