You go to the fuse box and look at each of the fuses' tops to see which one is burned/melted. Most fuses have glass tops thru which you can check to see if the conduit is intact. If it is burned you unscrew the fuse and replace it, making sure the replacement is of the same amperage. Make sure you turn off the main power before you do this or else you may get shocked. Most houses built after the 1960's use circuit breakers instead of fuses.

A fuse is a safety device that can only handle a limited amount of electricity. If too much power goes through that electrical circuit, either through draw (too many things plugged into one circuit) or a power surge, the wire inside the fuse that carries all the electricity to that circuit will melt and break - stopping the flow of electricity through the circuit. Automobiles and some electronic devices still use fuses; however, fuses were replaced by circuit breakers in homes over fifty years ago. A circuit breaker performs the same function as a fuse; however, when it is overloaded, it simply "trips" off and can be re-set. Whereas a blown fuse is destroyed and must be replaced.

The purpose of a fuse is to restrict amperage traveling through an electrical circuit to a specified value. It does this by inserting itself into the circuit and running the current through a metal strip inside the fuse. When the circuit is carrying to much amperage the metal strip will heat and then melt away, breaking the circuit and protecting anything that would be damaged due to the overload.

If an oven keeps blowing fuses it points to an electrical problem. This problem could be with the oven itself, it may be something in the house. In either case, you should have the wiring checked out.

Clogged filter inside. If you can see the outside unit is conducting animal hair, leaves, dirt, then these are all factors. If it is none of these, seriously see what is attached to your electrical circuits. Microwave with toaster? Move the balance of electricity.

Generally, you would have to replace the whole wire. However, a blown wire indicates a serious problem elsewhere such as a shorted out connection, a fuse that is too big for the wire to handle, or a malfunctioning circuit breaker. In any case, you need to call an electrician since these problems pose a fire hazard if you just replace the wire.

If your home has a fuse it is verry very old as fuses are no longer used, and have been replaced by Circut Breakers. Fuses were one time use gadgets while CBs were like a light switch and can be reset if it blows. As for cost, that is determined by the fuses use, type and size measured in Amperes.

Because the part that the fuse puts juice to is grounded or shorted out

A fuse blows because of overcurrent, short circuit or device failure. It interrupts the flow of electricity in the circuit to prevent devices from being damaged.

Why should you always switch off a circuit before replacing a fuse?

Main reason is for safety. Another reason is because if there is a heavy load, you may blow the fuse.


Will it work if you replace a 1.25 amp 125 volt fuse with a 1 amp 250 volt fuse?

Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.

What is a fuse panel?

a place where all the fuses are located together. In the house this is where the power is controlled to the lights in the house ect, and can be switched on/off independent of other areas of the house if that's what you want to do and if it is possible with your fuse panel/board. A fuse panel contains electrical fuses or circuit breakders in a central location in a building, vehicle, etc.


How do you get 120 amp fuse out?

Out of what? Is it a cartridge fuse, fuse block, disconnect panel? Turn off power and use fuse pullers for cartridge fuses. If its an old and corroded fuse block in your house, you would be wise to call someone who has the proper protective equipment to remove it.
