Question about Refrigerators
I have a Euroart dual zone wine cooler JG 168BL. The bottom section is fine however the top section which normally is set at 5oC is not cooling and is showing E4 on the display panel instead of the temperature. Do you know what this fault code is referring to?
E4 - Fridge thermistor short circuit.
check this area.

Hi and welcome to FixYa,
Initially, have you checked if the blower/fan drawing air from the bottom section upwards is turning? If not, that maybe be the culprit.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

What is the model number of your unit?

The beverage center and wine cellars have a temperature display for each zone. 12 volts
AC is supplied to the display board from a transformer in the unit compartment. The displays are only temperature displays and have nothing to do with any cooling function. A thermistor is used to sense temperature for each zone. The thermistor for the bottom zone is located inside the lower portion of the separator. The thermistor for the top zone on the wine cellar, (mid zone on beverage
center), is located in the upper portion of the separator. The thermistor for the beverage center upper zone is located on the inside of the 2-piece evaporator cover. It is on the right-hand side.
The mid temperature for the bottom zones on either unit are 60? Fahrenheit plus or minus 5 degrees. The mid temperature for the mid zone on the beverage center and the top zone
on the wine cellar is 45? Fahrenheit plus or minus 5 degrees. The mid temperature for the
top zone on the beverage center is 38? Fahrenheit plus or minus 5 degrees. I think at tis time you should check each section with a pocket size digital thermometer to cofirm tha the mechanical thermostat is within calibration. Click Here=> 4344690 Temperature Control

I believe the problem may be in the PCB transformer shown at the bottom right corner of the wiring diagram. It is possible o change the transformer but I have not been able to find the board that powers the LED temperature readouts. If needed let me know and I will call Whirlpool mfor you, Thanks, Sea Breeze
