Defrost Issue - GE Artica

I started seeing rising temps in both the Fridge & Freezer.
I don't think the coils are defrosting properly. I took the icemaker, shelves & coil panel out of the freezer, defrosted the coils with a hairdryer Sunday night. Fridge is now down to 37 degrees and freezer is at 11 and still dropping.
I checked the freezer around 10:30 last night, it was in a defrost cycle. The element was glowing. When I looked at the coil this morning, the bottom was completely defrosted whereas the top still had a heavy buildup of ice.
I am being told that this is a possible motherboard issue. Should I be seeing a complete defrost of these coils on a daily basis?
If I let this go long enough, the Evap Fan will get ice buildup and stop spinning at full speed. The temp in the fridge & freezer will rise due to the decrease in airflow.

If the element is glowing, how can it be a motherboard issue? BTW, I thought PC's have MB's not fridges. Is it possible the coil is shorted so only part of it is heating? Also, if the fridge was just manually defrosted, how did the top get a heavy buildup of ice in less than a day?
Should I be

Depends on the fridge. Some defrost every day, some may go a couple days.

Similar issues with same fridge a few months ago, still barely under warranty. Temperatures used to shoot up and down 8 to 10 degrees every few days. Technician replaced the controller board. It's been rock solid since then. Tech said that GE has been having problems with the controller, been replacing a lot of them. Given the cost of the controller board, icemaker, etc for that fridge, ended up buying a 5 year service contract from them. The cost of one icemaker (according to the tech) covers the cost of the contract for 5 years. With our water here in AZ, we tend to go through icemakers fairly quickly.

Have similar issue on GE frig last month while renting in FL. Called GE service., It was the defrost heater. Apparently they were having problems with them for they advised they had a flat rate for replacement of the heater ($100) for the first 5 years and this unit had a day to go...all from their records.
