Commercial Refrigeration Maintenance: The Checklist That Prevents Breakdowns

Most refrigeration failures are not sudden: they are weeks of a struggling unit that nobody looked at. A short routine, done consistently, prevents the majority of service calls and keeps compressors alive well past their warranty.

Daily, during service

• Log temperatures at open and close; anything drifting above 41°F gets investigated the same day.
• Wipe door gaskets and check they still seal (close the door on a dollar bill; if it slides out freely, the gasket is tired).
• Keep product clear of fans and vents inside the cabinet; cold air has to circulate to hold temperature.

Monthly

• Clean the condenser coil. In a kitchen full of flour dust and grease aerosols, a furred coil is the number-one cause of lost cooling and dead compressors. Power the unit down and brush or vacuum with the fins, not across them.
• Check drain lines and pans for clogs and standing water.
• Inspect hinges and self-closers so doors actually shut on their own.

Quarterly

• Replace worn gaskets rather than living with them; they are the cheapest part on the unit and the most common cause of temperature drift.
• Check that shelving, casters, and levelers are sound and the unit still sits level (doors seal badly on a tilted cabinet).
• Have anything you cannot rule out yourself looked at by a professional. Genkraft is backed by a nationwide network of service agents.

Every Genkraft unit ships with a one-year parts and labor warranty and an additional four-year compressor warranty; the warranty page has the details. A clean coil and a good gasket are still the best warranty you can give yourself.
