Service Diagnosis
• No ice, water in reservoir, but no spray
– Check water pump
• No ice, water in reservoir, sprays, ice forms but
harvest cycle does not start
– Check evaporator thermistor
– Use ohmmeter, check resistance for the sensor’s
temperature
• Measure suction line temperature closest to
sensor
• Check chart for proper Ohm reading at that temp
•Example 1
o
F = 82661 ohms – or use ice bath. 30
to 32K ohms at 32 degrees F.
