Frequently Asked Questions About Domestic Refrigerator Repair:

Can an upright freezer be converted into a refrigerator

Yes, but you may have some problems. You would have to install a different cold control as the original won't let temperatures be high enough set on minimum.

Also, if the freezer is of the design that has the refrigerant lines circulating through the shelves, you may not be able to place food items directly on these shelves.

The control you need if the lines are in the shelves, is an air sensing one. You can buy these as used for temporary controls or try a DR316. If the refrigeration lines are in the walls not the shelves you would need a control a heat leakage defrost system and comes in a kit that would make it adaptable for interfacing on your cabinet, try part number VT9.
