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?

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!
