A reach-in cooler that is not staying cold is usually caused by a dirty condenser coil, blocked airflow, worn door gaskets, a dirty or iced evaporator, an overloaded or poorly stocked interior, or low refrigerant. Clean the condenser, check the gaskets and don't block the interior vents; if it still won't hold temperature, call for commercial refrigeration service to protect your product.

Frequently asked questions
Why won't my reach-in hold temperature after restocking?
Overloading or blocking the interior vents stops air circulation. Leave space around the vents and let it recover.
How often clean the condenser?
Every 1 to 3 months. It's the most common cause of warming reach-ins.
