My Repair & Advice
After checked the cooling coil on the back of freezer showing ice built up around the coil, I thought defrost heater did not working that cause a lot of ice blocking cold air traveling.
While waiting the new defrost heater, I plugged in refrigerator through a timer that off and on every 6 hours. If not, refrigerator will turn off itself every 7-8 hours and make refrigerator not cooling several hours during the time I am not home and sleeping.
It took me uninstalling second time for changing defrost heater. I had to wait for over 8 hours after installed it to make sure not showing Er-dH code any more. My job was done and my refrigerator worked well after compare inside temperature and setting temperature by thermometer.
