What should I do if my amplifier fuse blows?

What should I do if my amplifier fuse blows?

If you cannot see all of the wire, disconnect it from the amp and see if the fuse blows when it’s inserted into the fuse holder. If it does not blow, the wire is fine and there’s probably something wrong with the amplifier. With more experience, you’ll be able to test for a short with an ohm meter.

Can a bad fuse be tested under load?

Depends on the exact fuse construction, this is why they’re always tested under load. A bad fuse can produce a positive continuity test on a meter without a load, and a good fuse can produce a high impedance value without a load.

Why does my DBlock amplifier keep blowing fuses?

If the main fuse isn’t blowing but one of the fuses in the dblock is blowing, that tells you that there is a problem beyond the distribution block. It could be that the wire feeding the amplifier is shorted to ground or there is something wrong with the amplifier. If you can see the entire length of the wire, make sure the insulation is intact.

How to check for a blown fuse on board?

If the fuse is open check FC1 and FC2. If needs replacement, board has to be lifted to desolder. If the fuse is healthy, check if there is any live supply coming out of that board anywhere, as the remote control receiving circuitry should be full time energized.

What should I do if I Blew my Fuse?

The Fix: Make sure the faulty device is unplugged and there is no damage to the outlet. First, test the circuit. Then check for any damage on or around the electrical panel. If you see any damage, call an electrician before doing anything else with it. If there is none, flip the breaker switch back to its operating position.

Is it possible to blow a fuse on a receiver?

As long as nothing is shorted out, your receiver should go back to normal. If your receiver is still on the fritz, you may have blown a real fuse.

What to do if your AV receiver fuses out?

If you find a fuse that looks burned out, it probably is. Replace it with a new fuse of the same amperage and voltage (available from electronics parts stores such as RadioShack for about 50 cents a pop) and you should be back in business.

Is the fuse box still in the House?

Most people nowadays have had the old-fashioned fuse panels (also known as fuse boxes) in their homes replaced by modern electrical panels with circuit breakers–if the fuse boxes were even still there when they purchased their houses.
