Blown Fuse

[smitt5]

How is everyone? I have a question about fuses. I have an APEX brand DVD player, model# AD-700. Great product by the way. Recently, stopped working. I removed the housing cover and noticed a blown fuse on the circuit board. The fuse is 250V, 2A, but smaller than fuses I'm used to dealing with. I have spare fuses rated at 250V, 2A, however, the length is 1 1/4, and diameter is 1/4. The fuse I need to replace is just under 1/4 in diameter, and approximately 13/16 (just under 1" in length), but the 250V, 2A ratings match. The fit will be a little awkward, but I think it can work. Is it safe to replace fuses with same ratings (amperage/voltage), but larger in size? Any feedback is much appreciated.

Re: Blown Fuse

hi, i would have to say no, trying to "jam" that larger fuse in there may break somthing. ratshack sells thoes small fuses. is that fuse on a circuit board? if it is, i would definately replace it with the same type.

Re: Blown Fuse

Don't be surprised if the new fuse you put in blows as well. Fuses usually don't just fail on their own accord. My guess would be the power supply circuit failed, or something else causing the fuse to blow like its supposed to.

I was in a rush and did not say all I wanted in my post. the post above is true a lot . i would say half of the time or more maybe 60 percent of the time. A fuse blowing and simple replacement does work but only half of the time or less. If the fuse was old and small like a 2 amp and pushed a lot it can wear out and then blow. Kind of like a light bulb filiment aging and burning out.

Back in my day this was the answer to the blown fuse question:

Re: Blown Fuse

I wouldn't say so in this case Philip. DVD players use small SMPS's so i doubt a two amp fuse was stressed in this application. As for the gum wrapper/nail solution...

Re: Blown Fuse

I agree it is an apex nice low cost unit as I remember. Its been hot around the states I wonder if the unit overheated a bit due to high room temperature. I can think over fuses blowing and being replaced and working or not.In real small units like his replacement was less likely to work then in a unit that could pull some serious juice. Something with a motor like an antenna rotor or a vaccum cleaner can blow a fuse if you stress the motor. His motor might have overheated due to a warm room and pulled too much juice.
By the way when I moved to this home in 1992 the central air went bad.
a big cap blew up in the outdoor compressor when the motor overheated in the next year 1993. The previous owner cut 2 pieces of copper pipe to fit the outdoor fuse box. so in 1993 we had 7 of 9 100 plus days in NJ it exploded the cap. It cost me a bundle to fix his fix. Can you imagine using copper pipe to bypass a 220 volt 30 amp fuse to an outdoor ac. LOL
