There are many ways to tell if a fuse is blown. The most obvious way of telling is if it doesn't work.
You can tell if your heal lamp relay is blown is by inspecting the fuses. If you look closely at the fuse, you will be able to tell it is blown or not. If you see a separation in the fuse, it is blown.
Remove the fuse and look at it. If you cannot tell if it is blown by looking at it then check it with an ohm meter.
A relay does not have a fuse. The circuit for the particular relay is fused. You can tell if the fuse is blown by testing it with an ohm meter.
Pull the fuse out and have a look at it and if the wire inside is broken then its blown
Unplug the refrigerator, remove the fuse and look at it. Typically the fuse will be dark in color, much the same as a blown light bulb.
Remove the fuse and check it with an ohm meter.
uh, if your tv is not working.aha
Test it with an ohm meter.
Not while it is in the fuse holder. Pull it out and if you cannot look and tell if it is blown or not, test it with an Ohm meter.
things don't work is the obvious answer.
Just remove the fuse and look at it.
I assume its because the something to do with electric doors dont work? Look for the fuse that is blown. You can tell with out removing the fuse by the visible link at the top edge of the fuse. If no visible link then blown fuse.
