DANGERDANGER
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.

Refrigeration coils 3000 Ohms
THERMISTORS
Two or four thermistors are employed. A type 2 thermistor is used
to measure the 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
For the refrigerator defrost information, please refer to the 2175R
model on page 32.
