Thanks for the prompt reply.
The condensor coils are clean. they are cool to the touch. I would expect them to be warm or hot?
The condensor fan is running fine.
The freezer has two separate sets of coils. The lower coils were frozen over and its heater was bad.
I replaced the defrost harnes wires which contained the two defrost heaters and new defrost terminator thermostat and did defrost the entire set of coils with hair dryer. The top set of coils had no frost.
no improvement. could the problem be the manuel damper. I doubt the timer is bad since it turns off everything ever 16 hrs. like clock work. I doubt the cold thermostat is bad because the compressor and all the fans work for the 16hrs. Could the compressor have two phases that I am fooled in thinking that its working-it is hot and vibrates for the 16 hrs.
What would you suggest. the settings are b and 9 now but no change with changes from b threw d and 5 threw 9 waiting 24 hrs after changes to let unit stabelize.
HELP PLEASE!!!!!!!

Ken, I would like you to remove the evaporator cover plate. Both evaporators should have an even frost pattern from top to bottom. If the unit has the evaporator & condenser motors running along with the compressor you should have an even frost pattern on the evaporator assembly. The evaporator coil temperature should be at -20 degrees Fahrenheit across the whole evaporator coil. This can be checked with a thermometer or a infrared temperature laser . If you do not have an even frost pattern on the coil and its only partially frosted you will get above normal temperatures like you are describing in your question. If you have a partial frost pattern you could have three possible problems and I will list them by the most common :
1) A low refrigerant charge due to a leak in the system 70% chance.
2) A bad suction valve in your compressor meaning defective compressor 25% Chance
3) A restriction in the refrigerant system normally in the capillary tube. This is due to oil from the compressor migrating into the capillary tube and restricting refrigerant flow.
