check the crankcase heater and reversing valve plugs arent swapped over,i know on some models the plug is the same.If not the valve will be stuck.Does the valve de energize and swoosh when rev valve deplugged.

Maybe it's 2 late put let us have a try. It's ether a mechanical or a control problem.i mean the valve is stuck or the coil is not energizing due to control problem or faulty coil
