Regular preventive maintenance extends the life of cold room doors by up to 30 percent. Here is what to check:

Rubber seals. Check every three months for cracks, hardening, or tears. Hardened seals lead to icing and increase electricity costs.

Sliding mechanisms. Lubricate every six months with silicone spray. Do not use grease, as it attracts dust.

Automation. Check sensors, buttons, and remote controls regularly.

Heaters. Test regularly, especially at sub-zero temperatures. A defective heater causes seals to stick and leads to cold loss.

Smart Frigo offers maintenance contracts and 24/7 emergency service.
