The component being protected by the fuse is drawing excessive current - has to be a board or something because the motor always draws more than three amps. Check the units schematic for locating the possible offending board. Must be relatively new since you indicate it is multispeed. Still under warranty?

The four flashes is failure of ignition. It could be the flame sensor dirty. The furnace tries to light four times before you get the four flashes. The board then locks out for one hour unless the power is removed and restored. You could try gently cleaning the flame sensor with fine steel wool. If you don't have fine wool you can use a crisp dollar bill.
with the burner firing the yellow flame sense indicator should be pretty much locked on or flicker briefly. If it just occasionally flashes on then the flame sensor rod needs to be cleaned.
hope this helps you.

Condination, wow that is an interesting spelling of the word Air conditioner.

Is this a gas furnace ? Newer high eff. gas furnaces do have cooler outlet temperatures. The installer should have checked the temperature rise and gas pressure. By adjusting the gas pressure and blower speed you can obtain a higher outlet temp, but you don't want the gas pressure to be higher than the manufacture specs and you don't want the furnace to run outside of the manufactures temp rise specs.

There are over temp and roll out sensors on the unit. They may be weak, or you may have a problem with flame adjustment, etc. Where did you cut that hole? The air flow has to be balanced in the room where the furnace is, if you have the furnace drawing in air from the room and not through the cold air return you run the risk of CARBON MONOXIDE being drawn out of the flue into the air feed and this can poison anyone in the structure.

i will assume you are talking about evaporator --a few reasons restricted air flow coils dirty -air filter clogging --fan not working or operating properly --low on freon ---turn fan on and with a spray bottle mix water and a little liquid soap and spray coils the fan will pull mixture thru coils keep spraying do not wipe the coils you can get injured and also damage coils an replace with new filter if still freezes over will need to check freon level and fan operation
