Try reversing hi voltage to the unit , a class i attended claims polarity will cause flame sensor fault .
Is there a head master on this condenser ? If it bypasses the coil hot liquid enters the evap and no cooling
sounds like your outdoor unit is not producing heat . When your thermostat calls it starts your heatpump and elect heat strips and when you are about 2 to 3 degrees of set temp the strips drop out...
for ac only oversizing a coil 1/2 ton is ok for greater humidity control but not for heatpumps
