With main ON/OFF switch on the control panel

in the ON position:

Check for DC voltage at

Terminal 4 on the

power module. See FIG. 6. It should be within

volt of the supply DC to the refrigerator.

Next, check for DC voltage at Plug 1

(Pl)

Terminal 1 of the power module. If no voltage is

present, then the switch is faulty and the control

panel should be replaced.

If DC voltage is present at

Terminal 1, check

for DC voltage on

Terminal 3 on the power

module. If there is NO DC power present, the

power module is faulty and should be replaced.

See FIG. 6.

The PAL@ Tester will allow for proper testing of

the integrity of the upper and lower circuit cards.

The PALmTester is available from your

Domet-

ic Parts Distributor.

4. GROUNDS

A quick, easy way to test for ground problems can be

done with a millivolt meter.

Connect a digital millivolt meter to J3 and

JlO

power module. See FIG. 4

FIG. 4

Main TerminalBlock

Pull one of the wires off the gas solenoid valve.

The millivolt reading should be 1-2 or less.

Put the wire back on the gas solenoid valve and

with the reignitor sparking, the digital millivolt

meter should read 5 millivolts or less at this time.

If the millivolt meter shows more than six

(6),

ground problem exists. Proceed to Section 5,

Installation of 3108702.675 or 3108702.683 Wire

Harness.

The digital millivolt meter should register between

25-30 millivolts with the gas flame burning.

Shut the manual gas cock valve off (see FIG. 5

7) and watch the millivolt reading as it drops. Note

the millivolt reading when the reignitorstarts spark-

ing (7-13MV). Repeat Step E several times. If

reignitor fails to spark or sparks continuously, it is

defective.

FIG. 5

MANUAL

GAS COCK

VALVE

Check all connections on the 6-terminal ground

bus bar for tightness and corrosion. Make sure

that the connection to the refrigerator’s

4-pole

main DC terminal block are clean and tight. The

same checks should be made to the coach’s

connection at the battery and converter.

INSTALLATION OF 3108702.675 or

3108702.683 WIRE HARNESS

In the event of repeated checklight occurrences,

Dometic recommends that the 3108702.675 or

3108702.683 wire harness be installed. The wire

harness serves as a precaution to lessen the possibil-

ity of intermittent check lights which can be the result

of loose or corroded grounds.

Remove the covers from both the power module

and the reignitor.

Remove the cable assembly connecting P3 on

power module to the gas solenoid and reignitor. It

can be discarded. See FIG. 6 and 6A.

Disconnect the white wire from

JlO

on the power

module and the

6-terminal

ground bus bar. It also

can be discarded. See FIG. 6

NOTE: Some models have the green/yellow wire

from the ignitor connected in with the terminal on

the white wire. It is removed along with the white

wire. See FIG. 6, 6A

Remove the green/yellow wire from the negative

terminal (-) on the reignitor and discard. See FIG.

6A&7.

Disconnect the thermocouple lead from

6-termi-

nal ground bus bar. Reconnect the thermocouple

lead to

JlO

on power module. See FIG. 6. Bend

the spade connector to a 45 degree angle so the

cover will go back in place. Be sure the spade

connector does not contact AC terminal at J8.

Plug the new cable into the P3 plug on power

module. See FIG. 6.
