Hi, I am sorry to hear that.
Its possible it may have a failed defrost component but we wont be able to tell that for sure until you do this.
I will stay with you as this could take a couple of weeks to be sure.
Im sure it was the RCD that caused this, but that could have been caused by many things not related to your freezer, storms, power line work etc;-)
Its not likely the Freezer caused the trip.
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a great weekend!
Also may I have the full model # of your freezer and its approximate age so I can check on a couple of things for you?
