Hotpoint soultion If my fridge is stuck in defrost, how to unstuck? If it is my compressor is there a reset? If the the refrigerant has leaked out will the compressor still work?

If the fridge is overcooling it could be the thermostat. If the defrost panel is permanently switched on, overcooling might not be noticed but the condenser will become quite hot.

If running continuously, there is no overcooling and the condenser remains cool, either the compressor is defective or the refrigerant has leaked away.

if compressor is running and no cooling is present --possible damage when defrosting causing loss of freon

No reset button. Could be defrost timer is stuck in defrost. Or bad thermostat or control board. Or bad compressor. Or sealed system blockage or leak.

WHEN U TALK ABOUT THE THERMOSTAT U MEAN THE COLD CONTROL THERMOSTAT OR DEFROST TIMER THERMOSTAT? WHEN UR PROBLEM SOUNDS MORE LIKE THE DEFROST TERMINATOR OR BAD HEATING ELEMENT, LOCATED ON THE FREEZER EVAPORATOR COILS? IF ITS STAYING ON ALL THE TIME U HAVE A DEFROST ISSUE? OR BAD SEALS ON DOOR AND DIRTY COMPRESSOR

If both section are not working as required then its compressor fault.The noise you noticed must be from compressor related parts,that are fan,the motor and relay.But If freezer is getting over cold and friezed and fridge section not getting cold then Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 4 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

I'm assuming you're meaning that you reset the "cold control" in the refrigerator area and it is not responding. Try resetting the T stat in the freezer to between 2 1/2 and 3 1/2 and see if the unit continues to run on. If I have this the other way around, set the "cold control" the same as the T stat. The "cold control" is just a flapper door, it doesn't control the compressor only the T stat in the freezer does..
If the T stat is set as I said and the unit just keeps on running and never shuts down except to defrost, the T stat is bad and needs replaced.
There is a chance that the flapper door in the "cold control" is stuck wide open. Removing the cover and inspecting it might tell you if that's happening.

Sounds like you have a stuck compressor. The buzz is the compressor trying to run but cannot.
A refrigeration mechanic with an hermetic compressor tester can reverse operate the compressor to get it unstuck

Is the back wall full of frost? If so you have a defrost problem, most likely the defrost is stuck in the run mode. this is located above the controls area in the fridge. 

Can you hear the compressor running? Is the fan inside the freezer running? It could be that a wire connection has come loose during the move. Was the fridge laid on it's side during the move? If so you probably have compressor oil restricting the refrigerant system. If compressor and fan are running you will probably need a qualified refrigeration tech to check it out.

Could be stuck in "defrost" mode. Happens a lot. See if you can hear if the compressor is running or the compressor cooling fan is running (in back underneath the unit). Worse case is the refrigerant leaked out and you have a sealed system problem.
