SAFETY INSTRUCTIONS
This manual has safety information and instructions to help users eliminate or reduce the risk
of accidents and injuries.
RECOGNIZE SAFETY INFORMATION
!
This is the safety-alert symbol. When you see
this symbol in this manual, be alert to the potential for personal injury.
GENERAL INSTRUCTIONS
This Universal Power Module Kit is a direct replacement
for all current refrigerator control boards, namely 2 & 3 Way,
and Americana. There is no need for a new Eyebrow Display; the universal board self-recognizes which display type
it is connected to therefore the eyebrow does not have to
be replaced. The installer must strictly adhere to the installation procedure below, paying specific attention to tabs J1
to J4; if not wired correctly damage to the board will result.
These instructions must be read and understood before installation of this kit. This kit
must be installed by a Dometic Service Center or a qualified service technician. Modification of this product can be extremely hazardous and could result in personal injury or
property damage.
REPLACEMENT INSTRUCTIONS
Follow recommended precautions and safe operating instructions.
UNDERSTAND SIGNAL WORDS
A signal word , WARNING OR CAUTION is used

A. 3308741.002 Americana and 2-Way AMES/
AES Refrigerators Universal Power Module Kit
1. Disconnect all wires and harnesses from circuit
board.
2. Remove old circuit board.
3. Disconnect P3 harness from gas valve solenoid,
ignitor, and ground terminal.
4. Replace P3 harness with new version. Connect
white wire to one side of the gas valve solenoid,
and the yellow wire to the other side. The secondary yellow wire spliced to the solenoid wire connects to the (+) of the ignitor.
5. Unscrew chassis ground screw from backplate and
attach black ground wire; reinsert ground screw
and firmly retighten.
6. Connect the red (+) 12VDC wire to J1 terminal.
7. Connect the Light/Heating Cable blue wire(s) to
either J2 or J3. In older refrigerators these two wires
are spliced together to one tab. In the future they
will be 2 separate wires.
8. Connect the longer of the two black Thermocouple
wires to J4 terminal.
9. Connect the positive (+) black 120 VAC Line to J5
terminal.
10. Connect the neutral (–) white 120 VAC wire to J6
terminal.
11. Connect AC Heater element wires to J7 and J8
terminals.
12. Connect remaining black Thermocouple wire to J10
terminal. This lead from the thermocouple is normally the shortest of the two.
13. Connect new black ground wire from backplate to
J9 terminal.

14. Connect P1, P2, and P3 connectors to the appropriate terminals on circuit board.
15. Snap cover into place carefully so as to avoid pinching any wiring. Secure cover to backplate with #4 x
1/2" self-tapping screw provided.
16. Place new wiring diagram decal over the old one.
17. Installation of this Universal Power Module Kit is
now complete
B. 3308742.000 3-Way AES/AMES Refrigera-
tor Universal Power Module Kit
1. Disconnect all wires and harnesses from circuit
board.
2. Remove old circuit board.
3. Disconnect P3 harness from gas valve solenoid,
ignitor, and ground terminal.
4. Replace P3 harness with new version. Connect
white wire to one side of the gas valve solenoid,
and the yellow wire to the other side. The secondary yellow wire spliced to the solenoid wire connects to the (+) of the ignitor.
5. Unscrew chassis ground screw from backplate and
attach black ground wire; reinsert ground screw
and firmly retighten.
6. Install relay by utilizing the screw hole (and screw)
used previously on the older style circuit board to
attach the cover to the backplate. Mount relay with
the connection terminals pointing to the right, and
mounting hole to the left.
7. Connect the two Blue wires from the P3 harness
to terminals 85 and 86 on the relay. See FIG. 1.

8. Using the tab connector end of the single Red wire
connect it to terminal 30 or the relay. The opposite
end will tap into the J1 battery input wire using the
SCOTCHLOC 562 as shown in Fig. 2. Follow instructions in step 9 to make this connection.

. Red wire line tap connection.
a. Disconnect battery input wire from terminal
block.
b. Place J1 connector tab input wire into outer run
channel of SCOTCHLOK. See FIG. 2.
c. Insert red tap wire from terminal 30 of relay
completely up to inner stop channel.
d. Clamp pliers onto top of u-contact and bottom
of case; make connection by driving the u-contact down flush with top of the plastic insulator.

11. Connect the 12V (–) lead from the DC heater to
the ground terminal strip.
12. Connect the red (+) 12VDC wire to J1 terminal.
13. Connect the Light/Heating Cable blue wire(s) to
either J2 or J3 terminals on the board. In older refrigerators these two wires are spliced together to
one tab. In the future they will be two separate
wires.
14. Connect the longer of the two black Thermocouple
wires to J4 terminal on the board.
15. Connect positive (+) black 120 VAC Line to J5 terminal.
16. Connect the neutral (–) white 120 VAC wire to J6
terminal.
17. Connect the AC Heater element wires to J7 and
J8 terminals.
18. Connect remaining black Thermocouple wire to J10
terminal. This lead from the Thermocouple is normally the shortest of the two.
19. Connect new black ground wire from backplate to
J9 terminal.
20. Connect P1, P2, and P3 connectors to the appropriate terminals on the circuit board.
21. Snap cover into place carefully so as to avoid pinching any wiring. Secure cover to backplate with #4 x
1/2" self-tapping screw provided.
22. Place new wiring diagram decal over the old one.
23. Installation of this Universal Power Module Kit is
now complete.
Important: When this Universal Power Module Kit is con-
nected to an AES display, the DC threshold level detection
is no longer available; board will continue to operate in DC
mode, even though voltage level is lower than normal. The
12VDC mode should only be used while traveling down
the road so the battery is constantly being charged otherwise the battery could be drained if unattended for a long
period of time. If 120VAC is not available, use Gas mode.
The RV owner must be notified of these changes.

Over the years of running a mobile RV repair service, having a dedicated place
to access service manuals for all the different appliances and components
found on RVs was something that I always had a desire to create.
I hope this resource makes your RV repairs easier, as it has mine, but please
be careful and follow proper safety practices when attempting to repair
your own RV.
If in doubt, please consult with a professional RV technician!
