After less than two years, the dual MR16 lights stopped working. I sent an email to tech support at the company, and they advised I bypass the 110V-12V transformer, and install GU10 bulbs instead (running the lights at 110V instead of 12V). They even sent me pictures showing what needed to be done, and offered to sell me their very own $50 kit, which made it all plug and play (and convenient). Before ordering anything, I looked over the unit a bit more. No power in or out of the 12V transformer. I looked over the circuit board, and found a blown 5x20 glass fuse hidden on the main circuit board. I had to pull a wire off the board to gain access, which was secured with a crimped-on female push-on terminal. When I tried pulling the terminal off the board, the entire male end that was soldered to the board pulled out along with it! I pushed it back in enough to make contact, but this connection is not solid, and cannot be trusted. Moving on, I replaced the fuse, and there is power into the transformer now, but nothing out. Obviously a blown transformer, but still wondering why the fuse blew. Having much DIY electrical experience with homes, boats, and cars, I knew I could easily re-wire these lights without buying a silly $50.00 kit. It's a two hot and neutral wires split to two light bulbs, not a NASA space shuttle for God's sake. After the re-wire, the lights work, but do not turn off. They are always on regardless of button position. Now the company is telling me I need a new circuit board (conveniently, again a $50 cost), and apparently they claim their units do not have a fuse on the board at all (even after I sent them pictures of mine). They also recommended I solder the male terminal that pulled out back to the board. They also had no explanation as to how the "mystery fuse" and board blew, and just blamed me for rewiring the lights without using their kit (typical). I'm guessing when the transformer shorted, the fuse did not blow fast enough to protect the board from damage. They refuse to acknowledge that, and will not cover any parts under good will, and will not even discount anything. They seem to believe 2-years of use is a long time. Also, to make matters worse, because I had the grills off, my wife decides to wash them in the dishwasher, since the RangeHoodsInc website says they are dishwasher safe. They came out looking horrendous! They are severely discolored, with white powdery spots and dark blotches and a very uneven tone all around. They blamed this on phosphate-free dishwasher soap! I clean a lot of metal in my dishwasher and have NEVER seen this before. And these are $60 to replace! No where on their website does it state to use a certain type of soap in the dishwasher. On the range hood product page, it says they are dishwasher safe not once, but TWICE! What a great way to treat a customer, especially for a 5-year young company, and a 2-year old $500 product! Anyway, just wanted to share my experience to those shopping for a new range hood. Go for something better quality, and with real customer support.
