Question:

Can I use a ceramic fuse in place of a glass fuse?

I have an less than 2y/o LG refrigerator (LSC27910) that blew a fuse this morning. There was no power going into it this morning despite a functioning outlet. Looked at the motherboard on the top of the fridge and noticed a blown fuse. It is a (removable (not soldering in) 15A 250V Glass Fuse. I went to Radio Shack, an appliance repair shop and an appliance parts shop and none of them had the exact fuse. RadioShack only had 15A 250V Ceramic Fuses. I received mixed messages about using the two interchangeably.What is the difference between these? Can I use the ceramic ones until I order the glass ones online and have them delivered; Do I even need to order the glass ones? Thanks!!

Answer:

The Glass or ceramic has no difference to the fuse proerties, Fuses normally come with both current rating and duration - slow blow, normal, or fast blow, normally identified on the end after the current rating example 2AS (slow) 2AF (fast) You can get both with different current ratings, and both with different duration characteristics However the glass type are more specialist for electronics and you are more likely to be able to get this with the correct duration characteristics. The glass offers visability of condition, some ceramic are also sand-filled for extra protection. Replacing the glass with ceramic is fine provided they are the same characteristics. You may have to try online say through RS.
