Hi Melanie - Update: I received a push button assembly and a capacitor parts from Zephyr. We consulted our electrician (who happened to be on site doing unrelated work), he told us that our existing push button assembly is working fine so that part was not needed. He did install the new capacitor and said that by the sound the unit was making he could tell that electricity is feeding the unit adequately so that's not the issue either. He carefully lifted one of the two grids on the side of the blower and noticed that the blower wheel (sorry for not knowing the proper technical terms) was stuck in place, kind of gummed up, which is probably due to some grease accumulation over the years. He manually prodded the wheel to make it spin freely. He did this to both sides of the blower and the unit started working again. However, we still have the unpleasant screeching noises but have regained use of the hood. We decided to use it sparingly as long as it extracts odors, steam etc until we can replace it (or find someone who restores these types of motors.....not sure how cost effective that route would be though....). Thank you for your question and I hope you find a satisfactory solution!

We installed an under cabinet Zephyr in our lakehouse build 8 yrs. ago. It was our first experience with an outside venting hood and we were astounded at its efficiency vs. the OTR MW vents we'd had before. I use it all the time and it has never required servicing. Last year we installed a similar one in our remodel at home. I'm very pleased with that one, too. My style hoods are nothing special to look at, but they unobtrusively do the job with a minimum of noise. I'd have no hesitation going with another Zephyr or recommending one to a friend.

nuppal we went with the Zephyr Venezia hood. We find it to be very quiet and does a great job. We have only had it about 6 months but we do a lot of cooking and the house is always smoke and odor free. The baffles are easy to clean.

@J Y Yes. We installed the two blowers in the Tempest II and have had it for over a year now. It was the best decision ever and the range hood is one of our favorite purchases during the kitchen renovation. It is not loud when you use it on speed 3 which is the speed we use all the time when cooking. We can still have a conversation in the kitchen at that speed without having to yell at each other. It has 6 speed settings and we only have to use speed 4 when we fry steak occasionally. The two blowers make such a huge difference in sucking up all the cooking smell. Can’t smell someone is cooking as normally the smell would travel up to the rooms upstairs. Very happy with Zephyr’s customer service as well as I called in a couple times prior to making my decision on a range hood and they had been very helpful in answering my questions. Let me know in case you have other questions.
