Turn on the main gas supply and take a

reading. If the manometer now reads 11 inches,

the thermostat is defective and must be

replaced.

If the by-pass screw test shows no change in

gas pressure, the problem lies with the gas

supply to the refrigerator. Shut off the gas

supply, remove the by-pass screw, replace it

with one that has an O-ring and turn on gas

supply. Remember to check for a gas leak. At

this time we will take a look at the rest of the

gas system.

The safety valve, or flame

consists of a brass alloy

failure

safety

device,

valve housing and

cap, an electro-magnet, and a thermocouple,

which generates 14 to 30 millivolts when heat is

applied to the tip. It is used to energize the

electro-magnet in the safety valve. The purpose

of this device is to insure that the flow of gas is

shut off in the event flame is lost at the burner.

If this should occur, the thermocouple cools,

the magnet loses it magnetic field and the

valve closes. Most failures of this device are

related to the magnet, not the thermocouple.

Should this happen, the complete safety valve

should be replaced.
