Fuse Fused

[JustCruising]

Morning Everyone

Tried to turn on the lights over the vanity and the lights came on then went out immediately. Check the GFCI first but was not the problem. Checked the fuse....it was very hot to the touch and when I pulled the fuse, it was melted (fused together). I removed and replaced the 15 amp fuse and it did not blow. However, the lights over the vanity (and hallway) still do not work. Suggestions?

Thanks in advance!

Those lights are probably 12 volts and not associated with a GFCI if they are.

What fuse did you replace? Where is it located. If you post a picture of the fuse and where it was located it might help.

If things were that hot the fuse block may be damaged and not making contact. You need a test light or voltmeter to measure both ends of the fuse when in circuit and with the bathroom light turned off and then on. Trust me, I have a reason for this one based on your symptoms.

Frequently when an incandescent bulb fails, it draws a very high current for a short while. Check the bulbs first. The lamps are 12V so don't worry about your GFCI. If the bulbs are good (check carefully) and the fuse is good (don't over fuse, replace with the proper rating) then start tracing wires.
