The kitchen area is fairly well insulated, unless there was a really hard freeze you may not have damage. Put an electric heater on the counter, turn it on and close the door. After a few hours the ice should be thawed enough that you can run antifreeze thru the lines and also check for leaks. If the water pump shuts off when pumping antifreeze and doesn’t start running every few minutes you should be ok. Don’t forget to put antifreeze in the sink and run the pump. I would also check the outside shower on the other side. Good Luck!!!
