Electrical System
Problem: Water Trough Overfilling During The Freeze Cycle (continued)
Step 3 Allow ice machine to run. Disconnect the water level probe from control board terminal 1F, and
connect a jumper wire from terminal 1F to any cabinet ground.
Remember if you are past 6 minutes from starting, the ice machine will go into a freeze cycle water inlet
valve safety shut-off mode, and you will be unable to complete this test. If past 6 minutes you must restart
this test by disconnecting the jumper wire, restarting the ice machine, (step 1) and then reinstalling the
jumper wire to terminal 1F, after the compressor starts.
