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
•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.
