      Returning guest presenter Aaron Wilson is back for another exciting discussion. This time, we'll be talking about...
      The Science of CYA: How to Keep the Customer Safe, Document Your Work, and Not Get Sued
      We take on a lot of liability as appliance repair techs, and that can get us into sticky situations whether we've done anything wrong or not. Aaron will be teaching us all about how to navigate this side of the trade.
      We'll start by going over a tragic, real-world case study where a sloppy installation had lethal results, analyzing exactly how the installer's negligence caused this. From there, our scope will expand to what kind of safety precautions we should implement in our own work, both for the customer's sake and for our own.
      But even if you do everything perfectly, there's still the famous "technician witch hunt." Well, we'll also talk about how to deal with that by thoroughly documenting your work and putting yourself beyond legal reproach.
      A little about our guest, Aaron Wilson:
      Aaron has been in the appliance repair trade for about 15 years, starting out by doing installations before moving on to bigger and better things. He worked for C&W Services as a Sub-Zero authorized servicer for a time and thereafter joined Mr. Appliance of Highland Park in the Dallas area, where he worked for years as the lead technician and field service manager. These days, he's making sure that all the appliances of everyone's favorite fried chicken place are in tip-top shape as the Quality and Performance Consultant for the southwest branch of Chick-fil-A. In addition, he has taught many classes on refrigeration repair and advanced diagnostics, during which time he also developed training material for the soft skills side of things, which he is delighted to share with you. On top of all that he's a certified graduate of the Master Samurai Tech Academy, so he knows his stuff!

New to the forum, tech with 4yrs experience just getting back into the field after 11 years in the military, so playing catch-up on new stuff.

On LG refrigerators with the linear compressors with no cooling, I've been consistently reading anywhere between 600-1500 VAC on the CON201 terminals to the compressor, whether the connecter is hooked up or not. Several of my fellow techs have seen this as well. LG says the max VAC output to the comp should be ~180VAC. I've never had any issues with my Fieldpiece meter. Am I doing something wrong or is my meter insufficient for LGs?

The drive voltage to a linear compressor is normal 80 to 180 vac. The drive voltage is actual a square wave. Have seen about 300 vac as high with an inefficient compressor. My meter is a Fieldpiece SC46 and reads ok on LGs.

Did you realize the high voltage is normal ? Or what was the problem causing that high vac? I have the same issue

Answer is in the sentence. The board is driving the compressor harder to get cooling.
