I read a lot of forums on fridge drilling before making a decision to take matters into my own hands and use some science. My beer fridge is a fairly new Whirlpool Side-by-Side (ED2KVEXQ01) so I didn't want to take a chance on hitting a line and ruining the fridge. I also didn't want the traditional door mounted tap because I use the door for storage. I read posts about making an alcohol/corn starch paste which sounded messy so I decided to look for another method to locating the freon.
I picked up a thermal camera on Ebay for 85 bucks, I know that seems like a lot but it was worth it to me not to destroy my fridge. I used the SEEK thermal compact that plugs into a phone and you download an app. With that I was able to see the hot and cold areas of the fridge and just simply drilled where it was warmer than the rest. The results were excellent.
FYI: you don't have to register the camera to use it so you can buy it on Amazon and then just return it if you are not happy with the results
