Finally it's fixed, the ADC board clicks when shorting L1 and Test, 23 minute is the cycle of forced defrosting. Check AC across the heat element and across the whole heat assembly you will know if the termister is faulty. The culprit was the relay. Notice I replaced it along with the micro controller all together, which is a bad thing to do and I had a such bad luck, the new replacement controller was defective! After checking all parts on the board I decided to replace again the micro controller, bingo!

I used a higher rating relay, about twice as high as the original one with same footprint, it fits well.

Thanks for all the help from you folks, couldn't have done it without you guys.
