2. GAS SUPPLY

The refrigerator requires 11 inches water column with half

of all the BTU’s of the RV turned on (half of all

aDubances

turned on). With all the appliances off, the pressure to the

refrigerator should not exceed 12 inches water column.

The gas pressure for the refrigerator is taken at the test port

after the solenoid with the refrigerator operating. See FIG.

2A.

3. COMPONENTS

The Reignitor

is an electronic device that pro-

duces high voltage to create a spark to ignite a

flame at the burner, when refrigerator operates on

LP gas.

Verify proper DC power is at the positive (+) and

ground (-) terminals. The reading should be within

one volt of the voltage at the main terminal block

during the trial-for-ignition. (See Item 4, Grounds,

Paragraph E).

The reignitor installed on the refrigerators as

original equipment is part number 2931132019

(RV Gas Model 679). This reignitor is rated 50

MA. This reignitor may also be used on any other

model.

DO NOT

install the Channel Mark 6, Model

12E

Reignitor (shown below) as a service replace-

ment part. (FIG. 3 & 3A).

FIG.

The Thermocouple

is a component that extends

over three slots on the burner assembly so its tip

is in the path of the flame. During normal gas

operation, the thermocouple should produce 25 to

30 millivolts when connected to the lower circuit

board. Any reading below 18 millivolts

could

cause

erratic gas operation. NOTE: A reading of 18 or

less could be caused by low gas pressure or

improper thermocouple location.The thermocouple

should be centered over the burner and extend over

3 slots. See FIG. 2

2A.

The Burner

is a horizontal slotted metal tube

located below the flue tube of the cooling unit. The

burner should be cleaned periodically (at least

once a year). To clean the burner, remove from

the refrigerator and check for any foreign residue

(rust, spider webs, etc.) that could cause a deflec-

tion of the gas flow or flame. Soak the burner in an

alcohol based solvent and allow to air dry.

Rein-

stall in refrigerator and leak check all gas connec-

tions with an approved leak check solution. See
