COMPRESSOR/COIL SPECIFICATIONS
Electrocution can cause death or serious injury. Burns from
hot or cold surfaces can cause serious injury. Take precautions
when servicing this unit.
• Disconnect the power source.
• Do not stand in standing water when working around
electrical appliances.
• Make sure the surfaces you touch are not hot or
frozen.
• Do not touch a bare circuit board unless you are
wearing an anti-static wriststrap that is grounded to
an electrical ground or grounded water pipe.
• Handle circuit boards carefully and avoid touching
components.
To measure the start winding resistance, measure across the C and
S pins.
To measure the run winding resistance, measure across the C and
R pins.
Also check S to R and you should get the sum of the run and start
windings.
To ensure the windings are not shorted, check the S and R to
ground.

THERMISTORS
Four thermistors are employed. A type 1 thermistor is used to
measure the condenser temperature and determine the freeze and
harvest cycles in conjunction with the custom electronic board. A
type 2 thermistor is used to measure the ice bin, refrigerator, and
evaporator temperatures.
REED SWITCH
A reed switch is mounted to the underside of the cabinet and a
magnet is mounted to the door. When the door is closed the
magnet trips the switch which turns the light and display off. This
also sets an audible warning.
DEFROST
