To diagnose the gas system, connect a

manometer to the test point. With the

thermostat on maximum you must have 11

inches water column pressure at this point. If

you have 11 inches pressure, your problem

Is to the right of the test point. If you do not

have 11 inches water column pressure, the

problem Is to the left.

Let’s take a closer look at the gas thermostat.

In this drawing we will review how a thermostat

functions. When the thermostat is working

properly, the manometer will read line pressure

when set at maximum and the refrigerator is

trying to cool. From this drawing you can see

the gas flow when the refrigerator is trying to

cool. The gas flows through the thermostat at

line pressure without restriction. The valve is

(39)

The valve is now closed and the gas must flow

through the by-pass screw; the gas is now

diverted through the by-pass screw, which

regulates the size of the low flame. This

condition can only exist when the refrigerator is

cold or the thermostat is set to minimum or off.

If the sensing tube has lost its pressure, even

with the thermostat set on maximum, you will

have only low flame.
