Found Reach-In Cooler on and temp display reading 30 degrees. Removed panels and found evaporator coil froze up. Checked ohm readings on probes and found they are off. Will order new control kit. 10/30/19 Pulled cooler outside to de-ice. Removed faulty controls and installed new controls. Put unit back together and programmed new controller and tested okay. Pushed cooler back onto serving line.
