My guess is that possibly you are low on freon and you system uses a pressure switch to activate the compressor to run. Once the system looses gas, the suction pressure changes and the system stays off or turns off soon after it starts up

You will need to have a refrigerant gauge set and attach it to the system to check the suction pressure on it. I would need to know what type of freon gas your walk-in is using.

Do you have any idea of what the tech is doing to the system when you call him out?
