Appliance Repair Questions? Ask a Technician for Answers ASAP
Good day and Welcome to Justanswer,
My name is ***** ***** I will assist you today.
Please allow few minutes while I check its schematics and then type the answer.
This indicates temperature issue and/or an air flow problem due to heavy ice build-up inside the rear wall of the appliance.
Please try this to solve the issue:
Leave it unplugged and empty with door open for around 12-24 hours.
Then plug it back (expect some water on the floor) and wait for another 4-8 hours so it gets back to optimum temperature.
The problem should be resolved.
However, if the issue appears again then the problem is with defrost operation.
You will have to test/replace the temperature sensor and/or defrost heater element to resolve the issue.
Alternatively, you may call Zanussi at 03445 610 645 to book repair.
If there is anything else I can help you with, please let me know.
OK sure, please provide its correct model number and PNC number as I cannot pull up anything with Model zR8934FX2. 92034517-02.
Please check this IMAGE (part#42 is defrost heater and part#43 is thermostat).
If any of this is faulty these issues may occur.
I believe the control unit is fine and not causing this issue.
If you want to test/replace it yourself then unplug the appliance and remove the rear wall and then test these parts with a multi-meter for open circuit, replace the part that is faulty.
You're welcome and Good Luck.
