having an issue identifying the fault on a frost free freezer? Had a error light on the panel, switched off unit and restarted and error light away, yet the freezer is not reaching temperature?
The compressor is running hot, I think it is either a regass or blockage in the system or a compressor fault? which means gauges to determine the sealed side fault? is there anything I should check before approaching this more costly aspect?

Thanks for any advice
