I have a house for sale that has a window unit in the living room. The air has been running fine all summer until just the past few days. As soon as the fuse is changed, the air will run maybe 30-60 sec and then will blow the fuse. We recently had the house treated for mold and not sure if the moisture could have anything to do with it??
there must be another large appliance that is on the same circuit. Check all the places the mold guys went to and see if they unplugged something and move the plug to another recepticle. Next time fuse blow tour the whole house to see what else is not working especially the basement/attic/storage areas
How old is your house FUSES! Most have breakers. Check if you have put something else on the same circuit, an a/c unit will take almost 15amps and any extra will blow the fuse. You could use a 20amp fuse but no higher. or use a 15amp slow blow fuse. They will take over 15amps for a short time.
you have a short somewhere in the wiring. You should not run it again until you locate the short, because it can cause a fire, and/or ruin other expensive components.
