Wasnt cooling at all so Replaced compressor relay and that got it running. Now temperatures in freezer is -20 and regular food compartment is 25degrees. Any ideas for repair?

See the attachment for the tech sheet.
If the condenser/compressor fan is also staying on then you know it is a temperature control issue.
When you diagnosed the original problem did you disconnect anything that could effect the temperature control?
If yes go back and check that area.
Run the diagnostics.
Tried diagnostic test. Thermisters check ok.
Since the thermistors are OK then I would say that the control board is the problem.
