7)Wipe down the float switch assembly's housing, shaft, float, and retainer rod with a mixture of 1 part of recommended cleaner Hoshizaki "Scale Away" or "LIME‑A‑WAY" (Economics Laboratory, Inc.) and 25 parts of warm water. Clean the inside of the rubber boot and hose with the cleaning solution. Rinse the parts thoroughly with clean water.

8)Reassemble the float switch assembly and replace it and the rubber boot in their correct positions. Reconnect the vent tube and the flush tube.

9)Move the control switch to the "ICE" position.

10)Replace the insulation panel and front panel in their correct positions.

E.Thermistor Check

To check thermistor resistance, follow the steps below.

1)Turn off the power supply.

2)Remove the front panel, then move the control switch to the "OFF" position.

3)Remove the control box cover.

4)Remove the thermistor. See "V.L. Removal and Replacement of Thermistor."

5)Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 minutes.

6)Remove the white thermistor connector from the control board WHITE K3 connector and check the resistance between thermistor leads. Normal reading is within 4.7 to 6.2 kΩ. If outside the normal reading, replace the thermistor. If inside the normal reading, continue to the next step.

7)Replace the thermistor in its correct position. See "V.L. Removal Replacement of Thermistor."

8)Reconnect the white thermistor connector to the control board WHITE K3 connector.

9)Replace the control box cover in its correct position, then turn on the power supply.

10)Move the control switch to the "ICE" position.

11)Once the harvest cycle starts, begin timing the harvest cycle.

12)The harvest timer should expire and terminate the harvest cycle within 2 to 3 minutes. If the harvest timer does not expire and terminate the harvest cycle, the harvest timer is bad and the control board should be replaced. See "V.P. Removal and Replacement of Control Board."
