Major Appliances/refrigerator problem


I have an old MasterBuilt commercial display refrigerator that was just filled with freon by a technician. He checked everything else out, said the compressor looked and seemed to work fine. I have it plugged into a power strip via an extension cord. He said this was fine, as long as I didn't plug anything else in it like a portable heater. After he left, I noticed the power fluctuating. Should this be on its own dedicated outlet? It isn't huge, but I was wondering if the power fluctuation is a bad sign that something else is worn in it or if I simply have a low power source?

Not sure.....simply placed a voltage meter in the outlet strip and monitor the voltage at the strip.....You will see if the voltage is fluctuating.  A/C power normally much?  TEll me and I will tell you if this is within range.

Waiting to hear from you,
