How to Properly Maintain a Display Fridge: A Complete Guide for Retail and HoReCa

Why Proper Display Fridge Maintenance Matters

A display fridge is one of the most important investments in a food retail shop, supermarket, or HoReCa establishment. Its optimal performance directly affects the quality of the products on display, energy consumption, and ultimately the profitability of your business. Neglecting regular maintenance can lead to costly breakdowns, stock losses, and even penalties from health authorities.

Whether you own a MODACO display fridge for dairy products, cold cuts, or beverages, following the correct care guidelines is essential to protecting your investment in the long term.

Daily Cleaning – The First Step to a Perfect Display Fridge

Daily hygiene is not optional — it is an obligation both to your customers and under current health and safety legislation. Here is what you should do every day:

• Wipe interior surfaces with a damp cloth and a neutral, food-safe detergent.
• Remove food residues or spilled liquids as soon as they are noticed.
• Clean the exterior glass panels to maintain the unit's attractive commercial appearance.
• Check the condition of the door seals — they must be clean and flexible.

Avoid harsh detergents, solvent-based sprays, or abrasive sponges, as these can damage the stainless steel or plastic surfaces of the unit.

Defrosting and Deep Cleaning

Even though modern display fridges — including models from the MODACO range — are equipped with automatic defrost systems, a thorough deep clean is required at least once a month. This involves:

• Switching off the unit and transferring products to alternative refrigerated storage.
• Completely removing any ice build-up or deposits from the evaporator, where applicable.
• Washing the shelves and trays with warm water and food-safe detergent, then rinsing and drying thoroughly.
• Cleaning the condensate drain tray.
• Wiping down the interior walls and allowing the unit to dry completely before switching it back on.

Care of Technical Components

The Condenser – The Lungs of the Display Fridge

The condenser is the component that expels heat from the system. If it is covered in dust or lint, efficiency drops dramatically and the compressor becomes overloaded. Clean the condenser grilles with a soft brush or compressed air at least once every two months, especially in high-footfall environments.

Door Seals

Damaged or rigid seals allow warm air to enter the cabinet, forcing the compressor to work harder and increasing energy consumption. Check them monthly and replace them at the first signs of wear.

Operating Temperature

Continuously monitor the temperature displayed on the control panel. Any significant deviation from the set temperature may indicate a technical issue. MODACO display fridges are designed to maintain precise and consistent temperatures, but regular checks remain essential.

Common Mistakes to Avoid

• Overloading the unit – this blocks cold air circulation and compromises temperature uniformity.
• Placing the unit near heat sources – ovens, radiators, or direct sunlight reduce efficiency and increase energy consumption.
• Ignoring unusual noises – a new or persistent sound may signal a problem that, if caught early, costs far less to fix.
• Delaying repairs – a broken seal or a faulty fan left unresolved can lead to major compressor failure.

A Preventive Maintenance Schedule – An Investment That Pays for Itself

Refrigeration equipment specialists recommend professional servicing at least twice a year. An authorised technician will check the refrigerant level, the condition of the compressor, the operation of the thermostats and fans, as well as the electrical connections. This preventive intervention extends the service life of the unit and prevents unplanned shutdowns, which can cause significant product losses.

MODACO refrigeration equipment, manufactured in Romania since 1992, is built for durability and ease of maintenance, with easy access to technical components and spare parts available at short notice.
