Section H - Water System

To Test The Water Fill System

The wiring harness has two diodes in the line between the fill switch on the ice maker and the green coil of the secondary water valve, as well as between the water switch or relay on the freezer door and the secondary valve. The diodes are part of the wiring harness. (See wiring diagram, Figure

G10).

If the diodes fail open, the primary valve will not open for ice and/or water depending on what diode is open. The open diode will not affect the coil on the secondary valve. The secondary valve will open but if the primary valve does not open, you will not supply water to the secondary valve.

Resistance Check

To test the diodes you can use an ohm meter with at least a 10K ohm or higher scale. Take a reading across the diode, then reverse your leads and take another reading. The diode should check 10 times higher in one direction than the other.

Voltage Check

You can also use a volt meter to check the circuit.

Connect a volt meter to the valve coil of the primary valve, and connect a second volt meter to the green coil of the secondary valve. If the problem is with the ice maker, or the yellow coil of the secondary valve if the problem is with the water dispenser.

Digital Meter

If you are using a good meter you will read between

0-10 volts with a open diode on the primary valve, and over 90 volts at the secondary.

Voltage Drop From Heater

In checking the voltage on a ice maker fill, you must keep in mind that the coils of the water valves are in series with the heater on the ice maker.

The resistance of the heater will cause a drop in voltage. Example: If you have 110-120 volts at the outlet with the product running, then 92-101 volts will be present at the green coil of the secondary valve.

Valve Coil

The production valves use a 20 watt coil to open the valve. This should open the valve down to about 90 volts at the green coil of the secondary valve. If the voltage is lower than 90 but above 80, you can install a 50 watt service coil (Part Number

5304401081). Keep in mind, you must replace the coil on the primary and the green coil on the secondary valve to resolve the problem.

Voltage Readings are Different Between

Primary and Secondary Valve Coils

If you are getting 10 volts or less at the primary valve, but you are getting 85-100 at the secondary, you have a bad diode. If you are getting 48-58 volts at the primary valve and 90 or higher at the secondary, this is normal. With the current flowing to the primary valve coil through the diode, you are getting 30 cycle instead of 60 cycle current at the coil of the primary valve. Because of this, your meter will only read about 1/2 the voltage that is going to the coil.

No Water at Door

If the ice maker is operating but you cannot get water out the door, the test and operation of the diode is the same as for the ice maker, except for the voltage readings. On the water side, you should read the same voltage at the coil of the secondary valve as you have at the outlet. On the primary valve, the voltage should read 60-70 vac.

If the voltage is low at the primary but good at the secondary, you have a bad diode. If the voltage is low at both the primary and secondary, you have a bad connection or a bad switch in the door dispenser.

Diode Kit

If you have a problem with the diodes,order the diode kit (part number 5303918287. See Figure

H8.) The diodes are part of the wiring harness for the machine compartment.

Checking Water

If you do your voltage checks and find you have the correct voltage at the coils and the valve is not letting water through, replace the valve. To see which valve is bad, disconnect the water line from the filter to the inlet of the secondary valve. Place the line in a bucket.

Ice Maker Valve

Run the ice maker through a fill cycle and see if water will pass through the valve (Green Coil) and the filter into a bucket. If it does, replace the secondary valve. If it does not, remove the primary valve, disconnect the outlet line from the primary valve and run the ice maker through a fill cycle. If there is still no water, replace the primary valve. If water is coming through, replace the water filter.
