Input:
Question: what angle of door opening is required to slide shelves?
Document: The instructions do not mention that the plugs that cover the two holes on the door have to be removed by unscrewing them from the inside. It looks like you can just pry them out but they are actually screwed in.
It maintains the temperature well. I noticed one time when the door had been open for a few minutes, the temperature indicator showed it went up to 52 degrees. The compressor was on and quickly returned it to 48 degrees.There is a circulation fan that constantly cycles off and on. I don't really notice it any more, and it was not bothersome initially either.
Ran it for a few hours and played around with the controls. Worked perfectly. If we have the blinds drawn the sun hits part of the the wine fridge at certain times. The tinted glass door actually came in useful, even though we never even considered that issue. I would say it runs pretty quietly. It's as quiet as our brand new fridge and has a very slight hum when we open the unit and the compressor runs for a few minutes. Love the handle bar.
We purchased this wine refrigerator as a replacement to an existing wine refrigerator that had finally stopped working. The Uline that we were trying to replace was 3x more expensive! This one arrived within the two days promised and intact. We were able to easily slide it into our space and it had worked great. We have not noticed any loud noise that some have reported.
good design, shelves are removable. My big bottles fit fine with a shelf removed. A little tricky to get temperature to change but we figured it out.
Pros: Perfect fit for 15" under the counter space. Good capacity for the size, shelves can be removed to store bigger than standard size bottles. Reasonable price.Cons: Fan goes on far too often and is quite loud.
I read through the instruction on how to change the temp and unlocking the keypad to do it (easy enough).When I finally plugged it in, it quickly got to my temperature I selected (48 degrees).As other reviews have stated, the chrome metal ends on the shelves will be about ready to fall off.
It's a tight fit for larger champagne bottles, but removing the shelves takes car of it. Has a charcoal filter on the back that keeps the unit fresh especially if you plan on using it as a humidor to store cigars etc. Performance is good, cools very effectively and is about as quiet/noisy as your regular fridge. The price is definitely right.
Less then two months of owning this frig, and now none of the control panel works. It won't turn off, or adjust temperature. The only feature still working is the light. It has gone (on it's own) to the coldest setting, and I only have red wine in the frig..... NOT GOOD!. Also, the drawers are set too close together, so it's difficult to open the drawers when there are bottles on all the shelves.Not a good quality.
We needed something for a 15" space and wanted built in, which limits the options. I had a vinotemp which lasted about 6 years, which I guess is good for these things, but it never kept the white wine cold and the metal shelves were a nightmare. The Whynter product gets to lower temperatures, which is great for our whites. The shelves, are much better, although all of these wine coolers have shelves that are too tight. The unit is super quiet.
Answer: My Whyter slides under a granite top cabinet that was built to hold a 15 inch wide wine cooler. The door has to open a little beyond 90 degrees to slide the shelves out. Hope ths helps.
