Replacing the Halogen Lamp, Refrigerator

B.Check all connections in the LP gas system (at the back of the refrigerator) for gas leaks. The LP gas supply must be turned on. Apply a non-corrosive bubble solution to all LP gas connections.

The appearance of bubbles indicates a leak and should be repaired immediately by a QUALIFIED SERVICEMAN WHO IS FAMILIAR WITH GAS SYS- TEM AND REFRIGERATORS.

! WARNING

DO NOT use a flame to check for gas leaks.

C.Check the AES control system by connecting/discon- necting 120 volt AC power, start/stop the engine, etc. Compare the operation with the operation described in section Operating Instructions.

D.The LP gas pressure should be checked and the main regulator readjusted if pressure is incorrect. The cor- rect operating pressure is 11 inches of water column. The correct place to take the LP gas pressure is at the test port just ahead of the burner jet. (See FIG. 12).

E.Inspect the flue baffle. It should be reasonably clean and free of soot. Heavy soot formation indicates im- proper functioning of the burner. The flue and burner both require cleaning in the following manner:

1.Unplug the refrigerator power cord from the 120 volt AC outlet. (See FIG. 3).

2.Disconnect or shut off the 12 volt DC power to the refrigerator.

3.Turn manual shutoff valve to OFF. (See FIG. 1 & 12).

4.Remove cover from the burner housing. (See FIG. 1).

5.Remove the burner mounting screw and remove the burner assembly. (See FIG. 12).

6.Remove the wire and flue baffle from the top of flue tube. Clean the flue from the top using a flue brush. Blowing compressed air into the flue will not properly clean soot and scale out of the flue tube. Replace the flue baffle.

7.Clean burner tube with a brush. Blow out burner with compressed air.

8.Before removing burner jet, clean burner area of soot and scale that fell out of flue tube. Remove the burner jet. Soak the jet in wood alcohol and blow it out with compressed air. Reinstall and tighten burner jet.

NOTE: The color of the flame shall be clear blue over the slots of the burner. (See FIG. 13).

! WARNING

DO NOT use a wire or pin when cleaning the burner jet as damage can occur to the precision opening. This can cause damage to the refrigerator or create a fire hazard.

9.Reinstall burner, being careful that the end of the burner fits into the slot on the burner bracket. Check to make sure slots are centered under the flue tube and the thermocouple is positioned properly (tip of thermocouple extends over two slots of burner).

10.Check the electrode for proper location and gap. (See FIG. 14).

11.Turn on manual gas shutoff valve and check all fit- tings for leaks with soapy water.

12.Connect 120 volt power cord to the outlet and re- connect or turn on the 12 volt DC power.

13.Check LP gas safety shutoff. See page 6.
