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

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
