The fuse in an electronic device is one of your main lines of protection, safeguarding your gear from damage that may be caused by excessive current input or short circuits. While most home audio receivers do not have user-serviceable fuses, there a limited number of models that do. If your fuse needs replaced you can take care of it quickly and easily.


Step 1

Examine the back of your receiver for a fuse socket. The most common sign that a fuse may be blown is the inability of the receiver to power up. Check the outlet your receiver is plugged into first, to make sure that it's live. If it is, and the receiver won't turn on you can look for the fuse.

Step 2

Examine the back of the receiver for a small round knob with the word "fuse" printed on it or below it. Sometimes the amperage of the fuse will be given as well.

Step 3

Unplug the receiver and turn the knob to the left (counterclockwise). When the knob comes off, one end of the fuse will be revealed. Typically, the fuse will be a simple glass-type fuse.


Step 4

Pull the fuse out carefully (watch out for broken glass), and examine the fuse. If the metal strip on the inside is broken or burned through, you need a new fuse.


Step 5

Insert your replacement fuse. Put the cap back on by twisting to the right.

Step 6

Plug in your receiver. Turn it on and see if you get power to the receiver.
