DANGER

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.
