Arrived at location on 8/24/21 - Unit is a 2 door upright freezer, turned unit on and compressors came on, waited until unit got down to 40 degrees and then checked power to evaporator fans, found loose wire connection, repaired connection and fans come on. Amp draw is good on compressors and unit is dropping in temp. System is down to 10 degrees and is operating properly at this time time.
