Why would my AC blowing a fuse disrupt the entire unit?

    Denise, the bigger question is why is your AC blowing a fuse in the first place. Here's some possible help for you. When a fuse is blown the power can't be sent to your unit.

    So it doesn't catch on fire........electricity being hot when something gets overloaded it will shut off somewhere in the electricities circuit; what do you mean by unit? part of the house? apartment unit, complex more than one apartment? Ac unit itself?is it a window unit? or central AC unit? the AC unit if its big will need higher voltage to keep it running( Most common voltage ratings for AC units are 115, 125 and 220 volts, and amperage rating can run from 15 to 20 amps. The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit.) so the electrical system cannot handle the load and will shut off some apartments/houses are on multiple circuits so load is dispersed so only part of electric in house/apartment will get shut off if something blows, smaller apartments all on one continuous circuit when fuse/circut blows since its all together will shut everything off. you need to make sure you have 220 for large unit or if you have 220 and its on extension cord needs to be heavy gauge and rated for major appliances so it can handle the it a whole house cdentral AC unit? it could have over heated enuf to burn something up so it will not restart ,you may have a reset switch on unit that you cannot accesss without service tech. hard to answer help you without knowing exactly what you are talking/asking about and what kind of AC it is.

    Hi, Denise, very simply, the A/C fuse blew because something caused it to get hot somewhere along a wire that runs the unit. I would get, either an electrician or someone who really knows what they are doing, to come look at it and find out what made it blow in the first place. Electrical fires are killers. Please do not mess around with it.
