This turned out to be a two stage repair.

First attempt: Power off to hood. Removed the switch assembly thinking the problem was with the off/on button (two phillips screws and a gentle lift of the bracket to free the assembly). A sevice loop allowed me to lower the switch assembly and inspect the circuit board (CB) inside. I tried to operate the switch directly on the CB (i.e. bypassing the button hoping it might be something mechanical with the button, but still could not turn the lights off. Believing the CB was bad, I ordered a new one.

Power off to hood. I installed the new CB but I still could not turn the hood lights off.

I then ordered the next higher assembly circuit board (looking at the drawing).

Second attempt: Received the new CB. Power off to the hood. Getting this CB down so that I could replace it was a problem, as it was higher up in the hood and was very space limited, and having to work upside down, looking up into the hood. I used a double ended phillips screwdrive with 90 deg bends on both ends for the four screws holding the cover on the housing with the CB inside. The screws were recessed in the cover. Once I got the head exposed, I used pliers to turn the screws out a bit faster. We're talking a quarter turn at a time here. Once the cover was off, I dopped the CB down using the service loop. I removed the old CB and installed the new one, carefully changing out each connection one at a time. This required the loosening of two very small terminal screws in a cconnection block mounted on the CB for the power lines .You need a very small good quality screwdriver that fits the screws good to get them loose, as they were very tight and it would be possible to damage the CB if you twisted the block on the board (be very careful here). There are also four other slip on connector and one multi-pinned connector (care required here also to avoid bending any of the very small pins). No soldering required. I tested the system with the CB dangling from the hood and everything worked. I put the CB back up in the housing, making sure the wires would not be pinched by the cover (which only goes on one way in order to "clamp" the wires in place), carefully put the cover in place, and put the four screws back in, I then tucked the service loop back up out of the way, and put the hood filters back in place.

Power back on and a final test.... All good.

One other thing. The CBs should be handled with care reqarding static discharge. Touching the hood and handling the boards by their edges is probably a good idea.

I hope this helps someone.

Thanks PartSelect. com

P.S. Any chance of returning the first CB which I didn't need?
