Power board replacement

Tools:

1/4" nut driver
Anti-static wrist strap
1. Power OFF the refrigerator.
2. Power OFF the RV DC power to the

refrigerator.

For steps 3 through 5 see Figure 6-6.

3. Unplug the AC power cord

at the RV AC

receptacle and at the power board

4. Disconnect DC power supply wires at power

board terminals GND

and 12VDC

5. Disconnect the spark/sense electrode wire

6. Remove the power board cover 8/32 x 1"

hex screws

7. Remove the cover

For steps 8 through 12, See Figure 6-7.

8. Disconnect the AC heater wires at power

board:

a. Blue or Black

wire and Blue or Black “Y”

jumper terminals AC_HT_LO and AC_

HT_LO2

b. Yellow wire

and Yellow “Y”

jumper

terminals AC_HT_HI and AC_HT_HI2.

9. Disconnect the high temperature limit switch

wire leads terminals LIMIT IN and LIMIT

OUT

10. Disconnect the wire harness connector at

terminal P1

11. Disconnect the wire harness connector at

terminal P2

12. Disconnect the defrost board communication

wiring at power board connector P3

13. Disconnect daughter board jumper wire

assembly from power board

14. Remove the existing power board from the

base.

To install the replacement power board, reverse

WARNING :

High voltage can cause servere injury

and death. ONLY qualified RV service techincians

are autorized to remove this cover. Do not allow leak detecting

solutions to touch the electrical components. Many liquids are

electrically conductive and can cause a shock hazard, electical

shorts, and in some cases fire.

CAUTION:

12VDC supply connections are for low

voltage direct current only. DO NOT connect 120 or

240 VAC.

MISE EN GARDE :

Le courant à haute tension peut

causer des blessures graves et la mort. SEULS les

techniciens agréés pour véhicules de plaisance sont

autorisés à ôter ce couvercle Ne pas laisser la solution de

détection des fuites entrer en contact avec les composants

électriques. Beaucoup de liquides son conducters

d'électricite et peuvent préseter des danger d'électrucution,

de courts-circuits et parfois d'incendie

ATTENTION :

les raccords à courant 12 V c.c. sont

prévus exclusivement pour le courant continu à basse

tension. NE PAS le brancher au courant à 120 ou 240 V c.c.
