TROUBLE SHOOTING
1) When the Power Freeze and the Vacation (or Power Cool) buttons are held down together for 6
seconds during the normal operation, the Fridge and Freezer temperature LEDs will blink for 2
seconds at an interval of 0.5 sec.
2) At this time, when taking your fingers off the Power Freeze and the Vacation (or Power Cool) buttons
and pressing the Fridge (sending out a "Ding-Dong" sound, it goes into the Load Status Display
function.
3) The Load Status Display mode shows the loads which MICOM sends out operational signals to.
It only means that there are operational signals from MICOM. So, it does not indicate that those
signalled loads are in operation. And, even though a specific part is displayed as in-operation, it may
not operate due to its own defect or the defective relay on PCB.
4) The Load Status Display lasts for 30 seconds and it goes back to the normal operation mode.
When the Display Panel blinks for 2 seconds after pressing the Power Freeze and the Vacation (or
Power Cool) for 6 seconds at the same time
