ICEMAKER AND DISPENSER WORKING PRINCIPLES AND REPAIR
2-5. Function TEST
1. This is a forced operation for TEST, Service, cleaning, etc. It is operated by pressing and holding the Water amount selection
button for 3 seconds.
2. The test works only in the Icemaking Mode. It cannot be entered from the Harvest or Fill mode. (If there is an ERROR, it
can only be checked in the TEST mode.)
3. Caution! If the test is performed before water in the ice tray is frozen, the ejector will just pass through the water. When
the Fill mode begins (Stage 4), unless the water supply has been shut off, added water will overflow into the ice bin. If the
control doesn't operate normally in the TEST mode, check and repair as needed.
4. After water is supplied, the normal CYCLE is followed: icemaking
5. After Stage 5 is completed, the Ice Maker returns to MICOM control. The time needed to supply water resets to the pre-
test setting.
6. This icemaker function test takes about 90 seconds in case, there aren't ices in the ice tray. If there are ices in the ice
tray, it can take more than 90 seconds.
