ICE & WATER - AUTOMATIC DEFROST
SIDE BY SIDE - R134a
IMPORTANT SAFETY NOTE
The information provided herein is designed to assist qualified repair personnel only. Untrained persons should not attempt to make
repairs due to the possibility of electrical shock. Disconnect power cord before servicing this appliance.
IMPORTANT
If any green grounding wires are removed during servicing, they must be returned to their original position and properly secured.
CAUTION
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch to touch insulation; it will char at
200°F and flash ignite (burn) at 500°F. Excessive heat will distort the plastic liner.
IMPORTANT: PLEASE RETURN THIS SHEET TO ITS ORIGINAL LOCATION

temperature measured with gauge at mid-level FF thermistor location.
“OP-” if open; “SH-” if short
30 FZ Thermistor Activates automatically UI shows temperature sensed by FZ thermistor; pass if within 10°F of temperature
measured with gage at FZ thermistor location.
“OP” if open; “SH” if short
33 Ambient Thermistor
@ Main Board
Activates automatically UI shows temperature sensed at main board; pass if within +20°F/-10°F
of temperature measured with gauge at main board location.
“OP” if open; “SH” if short
35 FF Thermistor
Upper-Level
Activates automatically UI shows temperature sensed by upper level FF thermistor; pass if within
10°F of temperature measured with gauge at upper-level FF thermistor
location. “OP¯” if open; “SH¯” if short
34 Ambient Thermistor
@ UI
Activates automatically UI shows temperature sensed at UI; pass if within +20°F/-10°F of tem-
perature measured with gauge at UI location. “OP” if open; “SH” if short

Variable Capacity Compressor (VCC) Diagnostics (select models)
If test 38 fails, diagnose as follows:
Replace Inverter
→ Check at the connector
from main control into
the inverter (typically
BLK and RED wires)
Is Inverter receiving
10-15 VAC
and 1-5 VDC from
Main Control?
→ Check at Main Control
Board
(BLK/WHT and RED/BLK wires)
Is Main Control
sending 10-15 VAC
and 1-5 VDC to
Inverter?
no
→ Check at the connector from
the service cord into the
inverter (typically PUR and
WHT wires.)
Is Inverter receiving 115
VAC from power supply?
yes
• Check voltage supply.
• Check and repair
service cord wiring
and connections.
no
Identify and repair
damaged wires or poor
connections between
Main Control and
Inverter
yes
→ Remove inverter box
from the compressor
and check resistance
across compressor
winding pairs as shown.
Is resistance across
all winding pairs
equal?
yes
Replace Compressor
no
→ Check connections
from Inverter to
Compressor
Are connections
from Inverter to
Compressor intact?
yes
yes
Identify and repair
damaged wires or poor
connections between
Inverter and Compressor.
no
VCC Resistance Check
Check resistance between terminals
1 and 2, 2 and 3, 3 and 1.
If all resistances are equal,
compressor is operative.
Replace Main Control
no
