Continuous Flow Icemaker Service Manual WATER LEVEL CONTROL HOW WATER LEVEL CONTROL WORKS When water is introduced through the inlet fitting the float rises, the float pushes against a lever that in turn, forces the poppet assembly against the inlet fitting valve seat that seals the water off. See Figure 1 (page 7). Before the water inlet is sealed, the safety switch is operated. In the event of a water failure the float would drop down and operate the safety switch to shut off the machine. I

Continuous Flow Icemaker Service Manual BIN CONTROL The type of bin control used on all WCC and WCF Models is an electronic control. The control is supplied with power to terminals X1 and X2. Terminals X3 and X4 are a normally closed switch which open when the thermostat sensor bulb senses ice. The WCC1401-A/WCF1401-A uses 2 controls, terminals X1 and X2 are connected in parallel and terminals X3 and X4 are connected in series. The sensing bulbs are located in a 5/16” stainless steel tube wh

Continuous Flow Icemaker Service Manual ELECTRICAL CHECKOUT 1. Be sure the unit is disconnected from the power source. Remove the compressor electrical box cover. Check for obvious damage and loose wires. 2. Disconnect the fan motor leads. Since capacitors store energy, short the capacitor with a screwdriver. This will prevent shocks. 3. Disconnect the compressor terminal wires. OVERLOAD CHECK Using a volt–ohmmeter check the continuity across the overload, contact #1 and #3. If none, wait fo
