Load Mode used to check what is currently running

Press Freezer and Control Lock When it blinks let go of buttons and tap on Fridge

DEMO Mode lights remain on but heating and cooling switched off

Press Freezer – Fridge and Control Lock When O – FF displays you have entered the store demo mode Heating and cooling will be shut off ( Repeat process to get out of this mode)

Diagnostic Mode shows the errors codes

Press Freezer and Control Lock Keep holding until display stops blinking, if no errors recorded the screen will be blank. Wait 30 sec for normal operation

Testing Sparkling Assy this will check the function of the sparkling assy

Open one of the top fridge doors , press and hold sparkling level button for 5 seconds until the operation of the valve is heard. The door must be open, and the sound will confirm correct operation. Check sparkling assy voltage for 120V if no Sound is heard, replace if necessary.

Door OPEN press Sparkling Level

Door must be removed a little past 90 degrees

Make sure before measuring voltage of any DC component that circuit ground is used. Any marked GND on the main PCB will be your circuit ground. If Chassis ground is used, measurements will be incorrect.

A Sensor Resistance over 100K ohm is considered OPEN A Sensor Resistance under 2K ohm is considered Shorted

But Note that a sensor could also give wrong values if it is out of tolerance

Load Mode – Display Function

1) Quick Making + Sparkling M aki n g key are p ressed simultaneously for 8 seconds

2) Sparkling Load condition display mode shows the load that micom signal is outputting. However, It means that micom signal is outputting, it does not mean whether load is operating or not. That is to say that though load operation is displayed, load could not be operated by actual load error or PCB relay error etc. (This function would be appl ied at A/S.)

3) Sparkling Load condition display function will maintain for 30 seconds and then normal condition will be returned automatically.

Customer Ed info

E – Smart App

This app allows the customer to monitor energy consumption

Connect to the app store (e.g. Google Play, etc.), search for the app using the “Samsung E-Smart Ref.” keyword, and download and install the app.

Tip for Customer : If the customer is

having trouble getting the filter back into the fridge, tell them to turn off the water supply valve to fridge and dispense water from the water dispenser to lower the pressure.
