Is it possible????

It still sounds like the branch circuit, should be replaced with a grounded cable before anything else takes place, who knows who did this work, did they run a proper circuit extension, or might it be a bootleged circuit, which could cause all sorts of problems, fix the feed first.

Fuse failing
from excessive vibration?
High ambient temp?
Intermittent short?
Defective lot of fuses?
Bad mojo?

Fans are kind of funny, block them up and they draw less power.

I just wanted to make sure nobody missed this bit of insight - this will save you many headaches if you remember it. A fan running in a vacuum i.e. sealed or blocked draws very little current, but when you open louvers etc. the current draw will go up - blockages (dirty filters) actually help lower current draw :-?

How about hooking up the fan to an alternate supply (grounded). and letting it run for a while?

I was referring to the FUSE that had coded markings. It said 250V but no amps, just a coded part number I guess.

Where is this FUSE? Inside the unit????? You fed from a breaker right? What trips or blows?

What make and model? $1000 (Cheap*) GE - what? Is it discontinued??????

*I recently went looking for a hood - I canT afford what I install in other peoples homes......

If this fuse is part of the hood, and not the circuit fuse, the problem is clearly within the hood. A solid ground is more likely to contribute to blowing a fuse if due to a fault, not less.

I agree. :smile:

BUT, an internal fault on ungrounded equipment can be hazardous. No mater what is causing the problem '220' could get in hot water if someone was to get whacked by the unit.
