OVERLOAD

PROTECTOR

The

overload

protector

prevents

the

compressor

from

burning

out its

electrical

windings

in

the

event

the

compressor

becomes

overheated

or

draws

too much

current. The

overload

trips,

opening

the

circuit

to the

compressor.

lf

it

does this

repeatedly,

the

compressor

is

said to

be

cycling

on the

overload.

Cycling

on

the

overload

may

be

caused

by:

1.

Insufficient

air circulation

around

the

compressor

and

condenser.

2. Pull-down

on the

overload,

caused

by

a large

quantity

of

warm

food

placed

in the

refrigerator.

3.

Compressor

stalling

due

to

lack

of

pressure

unloading.

4.

Low line

voltage.

5. Defective

starting

relay.

6. Defective

compressor

-

shorted

windings.

TESTING

THE

OVERLOAD

PROTECTOR

To

test

the

overload

protector,

remove

the

compressor

terminal

cover.

Examine

the

bottom

of the

overload

for

signs

of arcing,

lf

signs

of

arcing

are

not

present,

either

check

for

continuity

or

connect

a

jumper

wire

across

the

terminals.

lf

using

a

jumper

wire,

plug

in

the

line

cord

and

set

the temperature

control

to

a

cold

setting.

lf

the

compressor

starts,

the

overload

is

defective

and

must

be

replaced.

lf the

compressor

fails

to

start,

check

for

a

defective

starting

relay

or

compressor.

lf there

is

evidence

of

arcing,

do

not

connect

a

jumper

wire,

but

proceed

as

follows:

1.

Disconnect

unit from

power

source.

2. Remove

the

relay

and

overload

from

the

compressor.

3.

Connect

one

ohmmeter

probe

to

the

compressor

shell.

Make

sure

the

probe

makes

good

contact

with

bare

metal.

Connect

the

other

ohmmeter

probe

to

each

of the three

compressor

terminals,

one

at

a

time.

4.

lf the

meter

shows

no

continuity

to

ground,

install

the

relay

and

overload

protector

to the

compressor

terminals.

lf

the

meter

indicates

that

the

compressor

terminals

are

grounded,

replace

the

compressor.

5. Attach

a

jumper

wire

across

the

overload

terminals,

6.

Make

sure

the

jumper

wire

does

not

short

to

ground.

7,

Reconnect

the

unit

to

power

source.

lf

the

compressor

starts,

the

overload

protector

is

defective

and

must

be

replaced.
