Hi I am sorry to hear that.
Is there any excessive frost or ice on the rear wall inside the freezer?
Hi thank you for that info. if its a self defrosting model, as most are now, you have a problem.
What you need to do now is check the door seals, let me knwo if they all look like they seal ok?
If so, you will need to defrost this one for 24 hours with the doors open, I would put down a towel to soak up and residual water from the ice.
Then wipe it dry inside. and close the doors. Next turn it on and let me know how it operates then.
Please rate my service kindly so I can continue with you. That should solve the issue, but if it returns I will still be here for you no additional cost, and once you rate, I will add your question to my Priority list so when you write me I will see that and reply promptly ;-)
