Have you  inspected  the  condenser coil,  it is the  coil outside the unit, is there any obstructions  or is the fan blade  dirty?  is there heat  being rejected  from it? Is the compressor running?  when it shuts of is the compressor hot?

A refrigerator  is  a Heat pump in its  operation & theory.

I need to know more, I  would  forget  a board if it were mine  and put  an old electromechanical timer rather than the circuit board  unless the boards  cheap, if its  $400  forget it.
