SERVICE MANUAL

www.norcold.com

Read this manual carefully and understand the contents before

working on the refrigerator.

Be aware of possible safety hazards when you see the safety alert

symbol on the refrigerator and in this manual. A signal word follows

the safety alert symbol and identiﬁes the danger of the hazard.

Carefully read the descriptions of these signal words to fully know

their meanings. They are for your safety.

This signal word means a hazard, which

if ignored, can cause dangerous personal

injury, death.

This signal word means a hazard, which if

ignored, can cause small personal injury

or much property damage.

The storage of ﬂammable materials

behind or around the refrigerator creates

a ﬁre hazard. Do not use the area behind

the refrigerator to store anything, especial-

ly ﬂammable materials (gasoline, cleaning

supplies, etc.).

A circuit overload can result in an electri-

cal ﬁre if the wires and/or fuses are not

the correct size. Use only the wire and

fuse sizes as written in the “Installation

Manual.”

Incorrect installation, adjustment, change

to, or maintenance of this refrigerator can

cause personal injury, property damage, or

both. Have service and maintenance work

done by your dealer or by an authorized

Norcold Service Center.

Disconnect the AC and DC power sources

before doing any maintenance work on

the refrigerator.

Do not bypass or change the refrigerator’s

electrical components or features.

Do not spray liquids near electrical outlets,

connections, or the refrigerator compo-

nents. Many liquids are electrically con-

ductive and can cause a shock hazard,

electrical shorts, and in some cases ﬁre.

Do not touch the evaporator or other metal

parts inside the refrigerator cabinet with

wet hands because they can freeze to the

refrigerator.

The rear of the refrigerator has sharp

edges and corners. To prevent cuts or

abrasions when working on the refrig-

erator, be careful and wear cut resistant

gloves.

Do not remove the round ground prong

from any of the AC power cords. Do not

use a two prong adapter or an extension

cord with any of the AC power cords.

When you discard an appliance, remove

all doors to prevent accidental entrapment

and suffocation.

ATTENTION

WARNING

CAUTION

ATTENTION

WARNING

SAFETY

At regular intervals, make sure that the

refrigerator ﬂue, burner, vent areas, and

the air pathway between the vents is com-

pletely free from any ﬂammable material

or blockage. After a period of storage, it is

especially important to check these areas

for any ﬂammable material or blockage

caused by animals and insects.

Diagnostic Pre-Checks

Before performing detailed diagnostics inspect for the following:

1. Make sure the refrigerator is turned ON.

2. Make sure the door is closed and sealing correctly.

3. Make sure the refrigerator is correctly installed and that the

vents are not blocked.

There may be more than one over current

device in the refrigerator supply circuit.

Be sure to check both the RV and refrig-

erator.

4. Make sure the vehicle fuse or circuit breaker is intact.

5. Make sure the ambient temperature is not unusually high (more

than 110° F. / 43° C.). Maximum ambient temperature is 131°F.

6. Make sure that the air circulation inside the refrigerator is not

decreased by foods or by shelves that are covered with plastic,

paper, etc.

7. Make sure the freezer is defrosted.

8. Bypass the thermostat by disconnecting the wires and install-

ing jumper wire in place of thermostat. If unit works replace

thermostat.

After these pre-checks, if the refrigerator does not operate:

9. Remove unit from its enclosure; refer to "Remove and Install"

section.

10.Perform the diagnostics outlined in the "Self Diagnostics" sec-

tion.

11. If the self-test diagnostic tests do not reveal an error code, refer

to the "Diagnostic Symptom Chart" table.

Self-Test Diagnostics

The unit’s control module is equipped with a self-test diagnostic

function which can be read using a light emitting diode (LED). To

access the error codes displayed in the control module, you will

need the items in Fig. 2. Refer to Fig. 3 - Fig. 3.5 for diagnostic

instructions.

1. Attach the two (2) female blade connectors (A1, A2) to the

wire leads of the LED (A).

Fig. 3.1 - Attach Blade Connectors

2. On the control module (E), disconnect the 12 VDC input wire

Reading the LED

If an error code is activated in the control module and the LED is

connected, it will ﬂash a number of times. The number of ﬂashes

will depend on what error was recorded. Each ﬂash will last 1/4

second and after the code is ﬂashed there will be a delay, then the

code will repeat.

Write down all error codes; then refer to "Self-Test Diagnostic

Chart" below.
