SERVICE DIAGNOSIS 1. 10-MINUTE DIAGNOSTIC PROCEDURE The 10 minute check out procedure is basically a sequence check which can be used at unit start-up or for system diagnosis. Using this check out procedure will allow you to diagnose electrical system and component failures in approximately 10 minutes under normal operating conditions of 21°C or warmer air and 10°C or warmer water temperatures. Before conducting a 10 minute checkout, check for correct installation, proper voltage per unit nameplate and adequate water supply. As you go through the procedure, check to assure the components energize and de-energize correctly. If not, those components and controls are suspect. 1) Turn power off and access the control box. Clear any ice from the bin control actuator located in the bin. 2) Turn power on and place the control switch in the "ICE" position. A 5 second delay occurs. The "POWER OK" LED on the control board comes on. If the "POWER OK" LED is flashing (indicating a full bin), check the bin control. See "II. 6. [b] BIN CONTROL CHECK PROCEDURE." 3) One Minute Fill Cycle – The harvest water valve is energized. After 1 minute, the control board checks the float switch. If the lower float switch is closed, the unit cycles to harvest. If closed, continue to step 4. If the lower float switch is open, the unit repeats the 1 minute fill cycle until water enters and the lower float switch closes (low water safety protection during initial start up and at the end of each harvest). Diagnosis: If the water valve does not open, check for no supply voltage at water valve terminals, bad coil, or plugged screen or external filter (no water flow). If unit fails to start harvest, check for open float switch or bad 1 minute timer in board. 4) Initial Harvest Cycle – The harvest water valve remains energized, contactor coil energizes to start the compressor (and fan motor on a remote condenser unit), and the hot gas valve energizes. The evaporator warms and the thermistor senses 48 °F (9°C). The control board then receives the thermistor's 3.9 k signal and turns operation of harvest over to the harvest timer. The timer completes counting (1 to 3 minutes). The unit then cycles to freeze. Diagnosis: Check if compressor is running, hot gas valve is open, harvest water valve still open. Average harvest cyc...
