Range hood dead - fuses OK - no clue

We just had a 'burp' in the power: TV went off and the range hood lights and fan went off, then the TV came right back on but the range hood is still not working. The 12V fuse in the panel is OK and the fuse up in the hood itself is OK. I am at a loss as to what to check next. Every other system in the rig is working just fine.

Electrical is just detective work. It's a pretty short check list. Power to the switch? Power through the switch? Does the motor run with a jumper? Is the ground good? That's about it. The problem will be solved by the end of the list.

In order to even start this process to get to the where I can check the switch would require removing the vent hood and disassembling to the point that I could get to the switch guts. We are in a state campground in AZ and I do not have a complete set of tools to tackle this with. I was hoping that there is a reset switch or something other "simple' (obvious to all but me) fix.

Maybe if you post your year, size, and model of unit.

Did you actually test the fuses or did you just eyeball them? If you haven't tested them I would sugest doing so.

Step one: check fuse with meter.
Step two: go buy new fuse

And the other things on the same fuse are working.

I'm not familiar with the 2012 model. My antique trailer has an outside opening door that opens with a lever. If the door doesn't open all the way, the fan won't come on. It's probably not like yours.

Good luck finding the solution.

We had the same problem on our 2012 model just a few weeks ago.. both the fan and light were totally dead. My husband figured it was a fuse, but after checking decided it wasn't. It ended up being a loose pin connector.

There's a four pin connector in the wall that you can access by removing the L bracket under the vent. One of the pins on the connectors wasn't seated properly.

Was an easy fix and only took a few minutes!

Hope your problem is that simple!

Kim

After removing the screen/filter, there was an inline fuse on a small black box at the back of the hood which was blown. Now if my eyes could just see what all the miniature scribbles on the silver end caps signify...the whole fuse is .5' long! Since the hood is made in Italy, I am hoping that finding a replacement will be fairly easy.

Thanks to all for your advice and encouragement...what a great resource this forum is.

Well I finally tracked down the miniature 250V/3.15Amp fuse. Plugged it in and it blew...repeated, and it blew again. If I jumper it, the fan and lights work just fine. Sorry, but electricity is not my strong suit, and I am stumped once again. In my ignorance, I am tempted to just fashion a jumper from a piece of wire and leave it, but I'm unsure as to what could be the unintended consequence. More wisdom please.

What is the make and model of the range hood? Did the camper come with manufacturer manual on the range hood? Does it give you the correct size fuse for that range hood?

The fuse is there to protect something delicate upstream from it and as it did when you had the power surge or pulse, blow and do its job. I would not jump the fuse and direct wire the unit to the power source. Confirm the fuse size (there are variations in those too - SLOW BURN or thermal fuse is one). Figure out what caused the surge to the unit - shore power or camper problem? Fix that and change the fuse.

PLAN B: CALL AIRSTREAM Service Center and see if they have the info. The replacement fuse you mention does not seem the correct ratings for that application BUT I also am not the expert. You do have a warrenty - you may want to document an issue for the record with a service call and email for a reference.

Good Luck,
Mike

The manual for the range hood is silent on tech info, and 1/2 is in Italian where it was made.

I went w/ the Fast-acting fuse rather than Slow-acting on the assumption that the slow ones are for motors that surge draw at startup.

I'm going off the truly minute scratchings on the miniature fuse ends, but they do correspond to the 250V fuses at Radio Shack. I will contact Airstream for correct info and also to document the issue.

The burp has so momentary that it would be hard to localize as to shore vs rig.


Thanks!

Motown,

Did you get this resolved? I have the same range hood and my fuse just blew. Wondering how you fixed the issue permanently?

Don
