How to Change the Control Module from ACDC to DC:
1. Turn off all power to the unit, AC and DC.
2. Take a picture of ACDC module wiring for future reference.
3. Remove all wires from the ACDC module and remove the screw that holds the module in place.
4. “Hinge” the module towards the back of the compressor, and then remove the “3 Pin” plug.
5. Put the new DC only module onto the compressor, starting with the “3 Pin” connector.
6. Replace screw that holds the module to the compressor.
7. Starting at the bottom of the new module, plug in the thermostat wires as follows:
i. Black wire from thermostat > Red Resistor > “T” Terminal
ii. Red wire from thermostat > “P” Terminal
iii. Red Jumper wire from thermostat > “C” Terminal
8. The positive fan wire is “piggy backed” onto the positive DC wire when using the ACDC module.
The DC only module however, has a dedicated connection for the positive fan wire. Begin by
“un-piggy backing” the fan wire and the DC wire.
9. Plug the fan in as follows:
i. Black negative lead from fan > “F” Terminal
ii. Red positive lead from fan > “+” Terminal
10. Connect the light wires to the marked light connections on the new DC only module. Red to Red
and Black to Black.
11. Connect the DC wires from the old ACDC module into the connections provided on the new DC
module. Red to Red and Black to Black.
12. Unplug the 110V cord from the power box. This cord is no longer needed, as the unit is DC only
now. The White and Black wires that were connected to the “L” and “N” Terminals should be
tucked to the side out of the way.
13. Turn on the DC power to the unit. The unit should now be running on DC power only.

KOOL - REFRIDGERATOR
REMEDY INSTRUCTIONS
Disconnect the vehicles’ battery Positive and Negative, disconnect any House battery(s) Positive and
Negative, if equipped with a generator ensure it is off and lastly, ensure the vehicle is disconnected from shore
power. Block any tires/wheels to prevent the vehicle from rolling. Failure to do so may result in electrocution,
fire or other personal injury, property damage and/or death.
SERVICE:
Certain vehicles have Nova
Kool refrigerators installed in which the 12VDC/120VAC circuit board fail, causing the
refrigerators to turn off. In addition, the ventilation requirements of the refrigerator may need to be enlarged.
INSTRUCTIONS:
1. REVIEW THE VENALATION OF THE NOVA
KOOL REFRIDGERATOR, THE PROCEEDE WITH ONE OF THE
TWO FOLLOWING REMEDIES;
2. REPLACE THE 12VDC/120VAC CIRCUIT BOARD AS DESCRIBED BELOW;
3. PHOTO’S ARE ON THE NEXT PAGE
There are two separate versions of the required ventilation upgrade listed below;
If there is NOT a big vent below the refrigerator, please order part kit 1; F100073625 – KIT 1
Venting Kit One Contains:
Bottom Vent & Fasteners – #8 x 18
Top Vent & Fasteners – 2 ¾ x 12
Insulation - 3 pcs each, measuring 24” x 27” total 1.5 linear feet ea.
If the coach HAS a big vent below the refrigerator, please order kit 2; F100073626 – KIT 2
Venting Kit Two Contains:
Top Vent & Fasteners – 2 ¾ x 12
Insulation - 3 pcs each, measuring 24” x 27” total 1.5 linear feet ea.
Nova
Kool Venting and Board Replacement
While the refrigerator is on the shop floor, move the location of the fan from the side to the rear, slightly pointing upward
Reinstall refrigerator.
Inadequate venting can reduce your refrigerators cooling ability. Nova
Kool has also determined there are some of the
12VDC/120VAC boards are failing at the conversion point in the board. This will cause the refrigerator to turn off. You may
experience one or both of these scenarios. Contact Nova
Kool (604-523-6515) with the refrigerator serial number and they
will send out a new board. We advise to utilize the 12V DC only board to eliminate or prevent the board failure. 12V DC
only board will only pull power from your RV’s house battery bank. Essentially when you are plugged into shore power,
you will pull 12V power from your battery while your on board house converter is constantly charging the battery. So you
will be converting at the coach instead of the refrigerator.
Remove the refrigerator and install new board;
Remove the 120V AC power cord. Add the required vents below the refrigerator and above the Microwave;
For the vent above the Microwave utilize a 2.5” hole-saw and finish with a dremal type tool;
While the refrigerator is out, open the bottom platform ventilation transfer;
Remove the Microwave and open the air transfer cavity from the refrigerator cavity to the Microwave cavity, this will allow
the proper “chimney affect” and the added vent above the Microwave will eliminate the heat buildup and allows proper
flow;
Ensure all insulation is neatly tucked away from the heat transfer cavities and adhered to the inner chassis wall;
You have completed the remedy of this service bulletin.
Please claim the appropriate remedy repair code.
Thank you for your help!
