noticed last night Freezer was warmer than normal and ice maker not making any ice. all contents were thawed. fridge above is working normal.
freezer makes buzzing sound with a click at the end every few minutes

how can I be certain if it's the compressor? Is there something i can look at or see before i call a pro?

You need to get us a good model number first for me to look up the part. The one you listed isn't a valid #. I can get you a price for the part, but the labor piece will vary. It it will expensive though. Just guessing but, somewhere between $350 up to $600.

You'll need to pull the unit out from the wall and get behind it. There is a fan back there that keeps the comp running cool, make sure it's running. When you're back there, if you wait a few minutes, if it's the comp you'll hear it try and start. If it's already running when you're back there, then you can probably rule it out. From your description it does sound like it though.

If the compressor isn't running it will sure affect both sections. Have you done what I mentioned in my previous post?

Below is the part number for the compressor and price is $248.83. You'll have to check with local servicers to find out how much they would charge you for the installation if that is the problem.

Part number: AP3179960
