i measure 29 ohms. remember i did replace the defrost heater with a new dual element one,and i replaced the thermostat and thermister. i was only getting as cold as 28 degrees before replacing all these parts.i was at 4 degrees this morning but the coils are still all frosted up just like my pic shows ? and i still cant get to 0 degrees? thanks for all your help. what will fix the problem at this point??

is it possible that for the freezer to defrost properly the plastic panel needs to be reinstalled ? i still have it left off.
