My home air conditioner keeps blowing fuses.I changed them twice since Jun 1 already %26amp; they blew again today?
It is customary to protect a circuit for a 240v a/c unit with breakers at the panel, and a fused safety disconnect switch at or near the unit. If your unit is blowing 30 amp fuses, it could be several things. 1) you are using non-time lag fuses. The correct fuse type should be a time lag fuse. These fuses are rated to handle the %26quot;inrush%26quot; or short term high current draw required for the compressor to start. non-time fuses will blow under this kind of application. 2) The fuse holders in the safety disconnect switch are dirty, corroded, or damaged from overheating. If a fuse holder gets overheated or dirty, it won't make sufficient contact with the fuse ferrules, causing them to get very hot. This often results in the fuses failing internally, and in essence 'blowing'. Make sure the contacts where the fuse goes are clean and not discolored from overheating. 3) Your a/c unit may have a problem with the compressor, such as sluggish starting, or problems with the freon path, causing high compressor loading. This will cause the fuses to blow. In that case, you will need to have your a/c unit serviced.
Hope that helps.

Residential central AC systems, even newer ones, have a fuse block with two fuses (typically) located in the electrical box outside near the condenser unit. This is in addition to the circuit breaker located in the breaker box.

Simple, really. You need circuit breakers and more juice! 20/20 wiring at least. Your present electrical output cannot support the amount of electrical current your air conditioner is demanding to perform. This can be dangerous! Better have it corrected to prevent possibility of future overloading and, God forbid, fire!
i am wondering why a house that is 8 yrs old would have fuses, but the other answer is right, make sure the fuses are rated for more amps than what the a/c draws. also, make sure there is nothing else drawing current on teh same circuit-amps from something else would add to the total on the circuit. if the fuse is rated high enough, then you may want to try a time-delay fuse, which allows for a surge with out blowing. when a motor starts it takes more amps than when it is running. if that doesn't fix it, i think you have to spend the big bucks and call in a pro...
Sounds like either there is something wrong with the AC causing it to draw too much electricity...or the AC takes more juice than your fuzes are rated for. If your A/c draws 20 amps and you have 15 amp fuzes...well ...guess what?
call the guy duh
Could be a lot of things, first check to see if you have the right size fuse. The problem you are having could easily be caused by too low of amperage on the fuse. An old motor on the unit could also cause excessive power draw and blow the fuses.
BTW, why do you still have fuses? May be time to have an electrician give you a quote on putting in circuit breakers.
