Water Level Sensor1. Test using the controller’s indicator lights (sump empty and sump full). Unit must be powered up and theremust be water in the sump. Add some manually if needed. Locate water level sensor. Release from sumpcover and slowly lift up until the mid-length probe is out of the water. The sump empty light should come on,and if the unit is on the inlet water solenoid valve will open to fill the reservoir. Return the water level sensor toits normal position. If the unit is on and calling for ice the water will fill until the top probe is in contact with it, atthat time the sump full light will switch ON.2. Test with an ohmmeter. Disconnect electrical power. Open the control box cover. Unplug the connector at J9.Locate water level sensor and remove it from the sump cover. Test 1: Place one lead of the ohmmeter on thelongest probe and the other on the controller end of the red wire, there should be continuity.

Sump Empty Light Sump Full Light January 2015 Page 54

Temperature Sensors1. Check controller. If the sensor calibration is completely out of range, the code display will read either 5 or 7.2. Check with an ohmmeter.• Open control box cover, unplug sensor from J6. Water temperature probe:• Measure the temperature of the water.• Push and release the clean button.• Wait one minute.• Measure the resistance of the water probe (two leads next to the open socket) and compare to the resistance in the chart for that temperature. Any reading within 1000 ohms is acceptable.Discharge sensor:• Measure the temperature of the discharge line as close to the sensor as possible.• Measure the resistance of the discharge temperature sensor (two leads farthest away from the open socket on the harness connector) and compare to the resistance in the chart for that temperature. Any reading within 1000 ohms is acceptable.3. Alternate procedure: Remove both water and discharge sensors from their places on the ice machine. Putboth into a container of ice water. Put a thermometer in the water. When the thermometer is at 32 degrees F.,check the resistance of each sensor. The resistance should be within 1000 ohms of 32649.

Test Procedures - CompressorFailure to start.Single phase models. All have resistance start, capacitor run type motors. Check voltage to compressor at thecontactor. Compare the idle voltage (compressor off) to the active voltage (compressor starting). The supplyvoltage must not be less than the lowest rated voltage for the ice machine. If the voltage is correct, proceed tothe next step.Check starting components. Most models use a PTCR to cut power to the start winding after the compressorhas started. Check the PTCR for resistance. The resistance check must be when the PTCR is at roomtemperature – any temperature between 50 and 100.At that temperature resistance should be very low between 25 and 50 ohms. Also check resistance to ground,it should be infinite. If the PTCR is good, check the compressor windings.Measure resistance from Common to ground. It should be infinite. Measure resistance from Common to Run –compare to the chart. Measure resistance from Common to Start – compare to the chart.Compressor check for high amp draw. Measure amp draw of starting circuit. If it does not drop off immediatelyafter start up, the PTCR should be replaced. It is not practical to check a PTCR for resistance at hightemperatures as the resistance drops very fast as the PTCR’s temperature falls. If the compressor is drawingexcessive amps but is operating, the run capacitor may be open. Disconnect electrical power, discharge thecapacitor and measure its resistance. If open, replace it. If shorted to ground, replace it.Any time the compressor is replaced, the PTCR and run capacitor should also be replaced, or if the modelwas equipped with a potential relay, start capacitor and run capacitor, those should be replaced with thecompressor. Most Scotsman service compressors include those parts.Some systems use a potential start relay and start capacitor in place of the PTCR.Potential relay. If the compressor will not start, check the amp draw of the starting circuit. If very low, thepotential relay contacts or start capacitor may be open. Measure the resistance of the potential relay contactsand the start capacitor. If either is open it should be replaced. If the compressor starts but draws very highamps from the starting circuit, the potential relay may not switch off. In that case the relay should be replaced. January 2015 Page 56

Test Procedures - Fan motor1.
