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

Why Proper Maintenance of Your Display Fridge Matters

A display fridge is one of the most important investments for any food retail store, supermarket, or HoReCa establishment. Without adequate maintenance, equipment performance declines noticeably, energy consumption rises, and service life is significantly reduced. Furthermore, food products on display can be affected by temperature fluctuations, creating sanitary risks and financial losses.

At Modaco, with over 30 years of experience manufacturing display fridges and commercial refrigeration equipment, we have seen countless times how neglected maintenance turns a quality piece of equipment into a constant source of problems. That is why we have prepared this practical guide for everyone who wants to protect their investment.

Daily and Weekly Cleaning

The first step in properly maintaining any display fridge is regular cleaning. This is not just about aesthetics – it is also about keeping the equipment running at its best.

Daily Cleaning

Wipe all interior and exterior surfaces with a clean, damp cloth.
Remove food residues and spilled liquids as soon as they appear.
Clean the glass panels with specialist glass-cleaning products, avoiding aggressive solvents.
Inspect the door gaskets – they must be clean and free of mould.

Weekly Cleaning

Empty the unit and clean the shelves and trays with warm water and food-safe detergent.
Disinfect the interior with solutions approved for food-contact surfaces.
Check and clean the condensate drain.

Cleaning the Condenser – The Most Commonly Overlooked Step

The condenser is the component that expels heat from the system. When the condenser grille is clogged with dust and dirt, the compressor works harder, consumes more energy, and wears out prematurely.

Recommendation: Clean the condenser grille with a soft brush or a jet of compressed air at least once a month, or more frequently in high-dust environments (for example, bakeries or high-traffic stores).

Modaco display fridges are designed with easily accessible condensers, precisely to make this essential maintenance task as straightforward as possible.

Checking the Temperature and Cooling System

Maintaining the correct temperature is critical for both food safety and compliance with current sanitary regulations.

Check the temperature displayed on the control panel or with a reference thermometer every day.
The temperature in display fridges for dairy products and cold cuts must be kept between 0°C and +4°C.
If you notice that the unit is no longer reaching the set temperature, contact an authorised technician immediately.
Do not overload the unit with products – air must circulate freely between them.

Overloading is one of the most common mistakes encountered in practice and directly leads to increased energy consumption and uneven cooling of products.

Inspecting and Replacing Door Gaskets

Door gaskets are essential for the airtight seal of the display fridge. A worn or deformed gasket allows warm air to enter the cabinet, forcing the compressor to run continuously.

Inspect the gaskets monthly – they must show no cracks, deformations, or mould.
Test the seal by inserting a sheet of paper between the door and the frame: if the sheet slides out easily, the gasket needs replacing.
Replace damaged gaskets immediately – the cost is minimal compared to the energy losses they generate.

Scheduling Periodic Servicing with an Authorised Technician

Beyond the routine maintenance you can carry out yourself, it is essential to schedule periodic technical inspections with a specialist. An authorised technician will check the refrigerant level, the condition of the compressor, the operation of thermostats and fans, as well as all electrical connections.

We recommend at least one full technical service per year, and for equipment used intensively (supermarkets, hotels, restaurants), twice a year.

Quick Tips for Extending Service Life

Never place warm or hot products directly inside the unit.
Keep the display fridge away from heat sources (ovens, radiators, direct sunlight).
Ensure adequate ventilation clearance around the equipment.
Use the unit exclusively within the environmental conditions specified in the technical manual.
