Question about GE ZV850SBSS Kitchen Hood

Open Question

Transformer replacement Mine stopped working, traced it to a faulty transformer. Got the replacement but, oops, can't remember where the wires go!? I know where the 110 goes but there are 4 other wires - an orange and white pair (I presume that is the 12V pair, correct?) and a pair of light blue. Where do these two go? one to each side of the transformer? which pole? Thanks in advance

SOURCE: Hood Light Problem

This is a light socket problem, and it has plagued hoods for years simply because grease builds up there and is acidic. One fix is to disconnect the power and wash the socket with alcohol, then buff with steel wool being careful to leave no steel wool behind. After cleaning you will need to re-tension the little aluminum/brass button at the bottom of the socket by placing a screwdriver under it and gently lifting it about 30 degrees upwards. Replace the bulbs with ONLY the stated wattage bulbs indicated on the panel.

We have a SV168n-36 Spagna Vetro Range Hood and it works well but the lights are having problems now. They only come on intermittently and when they do come on once they heat up they shut back off.


I had the exact same problem with my Spagna Vetro hood. The fan worked fine, but the lights started working intermittently and then stopped working altogether. The problem in my case was a failed transformer, which sits between the power switch and the lights and is necessary to step-down the voltage from conventional 120v to 12v to support the halogen bulbs in the unit. Although there are several steps to resolving the problem (replacing the transformer), it's really not difficult. Here's what I did to solve the problem:

1) Shut off the circuit at the breaker (always very important :^) )
2) Removed the glass arch from the top of the hood. Four screws hold it in place and are accessed from above the unit.
3) Removed the access panel above the fan and light switches. This panel is visible underneath the glass arch, when the glass arch is removed. I slid the lower section of the decorative stainless chimney cover upward to gain complete access to the back two screws of this panel.
4) I unplugged the original transformer from the light on/off switch (connected with two yellow wires on my unit). Remove the wire-nuts and disconnect the 12v leads from black and white wires that connect the transformer to the halogen bulb fixtures.
5) Using a flat-head screwdriver, I pried the transformer off the metal surface to which it was adhered with double-stick tape. This was strongly adhered and took a bit of prying.
6) Found a replacement step-down electronic transformer at the hardware store. My hood takes only two 10 to 20 watt bulbs, so only a small transformer is required. The original one I removed was rated to 70 watts max. I replaced it with a transformer rated to 60 watts max. Either was more than sufficient to cover the 20 watt load produced by my two 10 watt bulbs. Cost of the replacement was about $15.
7) Connected the replacement transformer to the hood power switch. Here, I had to be a little careful to maintain the original polarity of the wires from the switch. This is because the original transformer, though it had one white and one black wire on its 120v side, was attached to the switch via two identical-looking yellow wires, using a non-standard plastic connector. The new transformer did not have one of these connectors on its 120v input wires (black and white), and I wanted to make sure that the I wired the replacement exactly as the original had been wired. Fortunately, the original plastic connector ensured a consistent polarity. When I looked at the end of the connector, one lead was square and one lead was round and noted that the square lead had been attached to the White wire on the original transformer. The replacement transformer also had a white and black wire for its 120v side. So, I marked the yellow wire from switch that attached to the white wire through the square lead. Then, I cut off the plastic connector from the yellow wires, stripped the sheathing from them about 1/4 inch, and attached the white wire from the new transformer to the previously marked yellow wire, using a small wire nut. I then connected the black wire from the transformer to the remaining yellow wire in the same way.
8) On the 12v side of the transformer, the wires are the same color and I did not pay close attention to polarity, simply connecting each to the spliced wires leading to the halogen bulbs (that I exposed when I removed the wire nuts from them in step 4, above) using fresh wire nuts.
9) The double-stick tape that attached the original transformer to the hood remained firmly attached to the metal surface of the hood and it was still very tacky on the surface that had been attached to the original transformer. So, after I tidied up the wires in the space, I positioned the new transformer over the tape and pressed it down firmly, which seemed to adhere the new transformer to the hood pretty well.
10) With the connections completed, and power restored to the circuit at the breaker, the lights worked fine, and the fan continued to work fine. I reversed the steps I used to expose the switch and transformer.

So that's all there was to it. The cost of parts was about $20 for the transformer and a bag of wire nuts. Investigating the problem probably took more time than the actual repair, which took about 20 minutes from start to finish.

DW, It is not the transformer. It could be the dimming controls. Also, instead of using a bigger transformer go in for CFL bulbs and reduce the load on the transformer. And contribute towards efforts to reduce global warming by using less electricity.

I have a Cavaliere 218 range hood and the lights don't come on. Lamp button illuminates, but no lights come on. Bulbs are good.


We have a Cavalier range hood as well that the two halogen lights stopped working. Bulbs were good and the light switch illuminated. I ended up ordering and replacing the transformer and it works great:

Rangehood lights not working


I have a Fabyka Range Hood and know three other people who have had this exact problem (i.e both lights go out simulatneously but fan works fine). In my case I was able to pin it down to the transformer used by the halogen lights. This is an electronic transformer so it is less tolerant of power surges and such.

In the case of Fabyka the transformer is a black box connected to the inside of the hood with sticky tape with a black and white wire and two red wires. It is only used for the lights.

It is connected to the AC power via a black and white wire. you can disconnect this and us an LED power tester (about $2-$5 at most hardware stores) and see if you have power when you hit the switch.

In my case it is a 70W 120v to 12v halogen transformer. You can by a replacement off Amazon for about $12 including shipping or you can by a new one from Fabyka for about $30. I would suggest getting a slightly higher wattage transformer (I bought a 105watt for a dollar more).

You will need to disconnect the power before replacing but it is an easy fix.

1. Disconnect the AC power connector (black and white wires.)
2. The red wires coming out are the 12volt lines. If there is a connector, you can disconnect this, if not, you may need to cut these off.
3. Pull the tranformer off the back of the inside of the hood.
4. Cut the connectors off the old transformer. (Unless you buy Fabyka's.)
5. Connect them to the new transformer using wire connectors or crimps. (Make sure you connect black to black, white to white, and red to red.)
6. Make sure you have no exposed wires.
7. Connect to the corresponding connectors inside the hood. Connect the AC connector last.
8. Verify that the lights work properly.
9. Use sticky tape (or Gorilla tape) to attach the connector to the inside of the hood.
10. Enjoy the light.

I can switch on lights and fan, but then they switch off


It could be either. Usually i would say its the control board, but its very possible that its the transformer. I would start with that, the trans=25$ then control board = 110$
Its the small transformer (blue/yellow/black/white) wires coming out of it.

Baumatic hood bt82.1 lamps blown..


Hi johnnyi6,

I'm Harvey the Master Plumber.

Your problem is: had a crackling noise then pop..looks like transformer has blown,replaced
but still no lights ..fan o.k...don't appear to be getting any power to transformer via switch?...how do you get push button switch out?...
bypassed light switch and lights o.k with new transformer..any ideas..

Yes, I agree, the switch went bad. It snaps in so you will break it during removal. I recomend you get the replacement switch first so you don't have a wire hanging out while you wait for the new one.

Feel free contact me again!
