Defy duette - freezer side not working

SOURCE: New Frigidaire side by side running constantly and still warm

If the frost build up is on the back panel of the freezer then it has a defrost problem which causes a no cool situation. Let me know more about this frost buildup and what you have done.

the unit is loosing the freon supply to the evaporator.you either have a leakage,a blockage or the compressor is not pumping to full capacity.

sounds like its froze up. the coil is in the back of the freezer and blows into the freezer via a fan then cold air is carried to the fridge via another fan. more than likely condensation due to weather conditions has built up on your coil and has froze up or your fridge fan has stopped working. unplug fridge for a day to let thaw, if this doesnt work check you air distribution fan in top.
as for the lights not working in the freezer the switch is on the left hand side of freezer wall under ice holding tank sometimes water from thawing ice get on it and it wont come out all the way, take a blow dryer to it to thaw and dry it out.

HI
If the compressor doesn't run, it is likely that the defrost timer is malfunctioning. This part is located near the compressor. To test the defrost timer:

Step 1: Unplug the refrigerator.

Step 2: Disconnect the wires from the timer and timer motor. Remove the timer from its brackets by backing out two retaining screws.

Step 3: Test the defrost timer with a VOM set to the RX1 scale. Clip one probe of the VOM to each defrost timer -- not motor -- wire, and turn the timer control screw shaft until it clicks. If the defrost timer is functioning, the meter will read zero. If the needle jumps, the defrost timer is faulty. Replace it with a new one of the same type.

Step 4: Connect the new defrost timer the same way the old one was connected.

To check the defrost timer motor, clip one probe of the VOM to each motor wire, setting the scale to RX100. If the meter reads between about 500 and 3,000 ohms, the motor is functioning properly. If the meter reads higher than 3,000 ohms, the timer motor is faulty. Replace it with a new one of the same type. Connect the new motor the same way the old one was connected.
