Freezer section of upright Refrigerator frozen up again. A couple of months ago, our top freezer section in our GE (model GTS18JBPDRWW) froze up and the temperature went way up in the entire unit. Fan in freezer was still working. (This refrigerator/freezer is located in the garage and has been working fine for 10 years) When this problem came up, I posted it and several of you gave suggestions. One person on Nextdoor suggested we remove the back panel inside freezer section and clean out the ice dam. (their fan needed replacing but our fan is working fine) We did what they suggested, using hair dryers and towels removed all the frost. Put it all back together and everything was working fine until yesterday. Then we noticed the temp gauge in ref. showed temp was going up........so the same thing happened again. We repeated removing ice, etc. and put it back together. Today it is working fine.
It appears as if the defrost cycle isn't working. Has this happened to anyone out there, and did you repair it yourself or hire someone? Please share a name and number if you hired someone and were happy with this repair person. Would appreciate any and all suggestions. Thank you in advance.
