Why Is My Commercial Refrigerator Leaking Water?
Water leaks from a commercial refrigerator can create both safety and hygiene issues in your kitchen. Puddles on the floor not only pose a slipping hazard but can also be an early sign of a deeper problem such as a blocked drain, condensation buildup, or poor insulation. In humid climates like Singapore, these issues can appear frequently if preventive maintenance is neglected.
How to Detect a Water Leak
Watch out for these signs:
Puddles forming under or behind the refrigerator.
Musty odours caused by standing water or mold growth.
Visible condensation on interior walls or near the door frames.
The drain pan filling faster than usual or overflowing.
If leaks appear intermittently, especially after heavy use or defrost cycles, it likely points to drainage or humidity control issues.
Why It Happens
Common causes include:
Clogged or frozen drain tubes blocking defrost water from flowing to the drip pan.
Cracked or misaligned drain pans leading to overflow.
High humidity environments, common in Singapore kitchens, causing excessive condensation.
Improper leveling, which prevents water from draining correctly.
Damaged door gaskets allowing warm, moist air to enter and condense on cold surfaces.

Why Does My Commercial Refrigerator Have Temperature Fluctuations?
Temperature fluctuations are one of the most common and frustrating issues faced by food businesses in Singapore. When your chiller or freezer struggles to maintain a stable temperature, it can directly impact food safety compliance under SFA regulations and result in costly product spoilage.
How to Detect Temperature Fluctuations
You can spot early signs of temperature inconsistency by:
Checking if your fridge display shows irregular readings or sudden spikes.
Using a data logger or recording thermometer, as required by the Singapore Food Agency (SFA), to verify and record temperatures over time.
Observing uneven cooling — for instance, one section of your fridge may feel colder while another is warm.
Monitoring product texture or thawing in freezers, which often indicates temperature instability.
Why It Happens
Several mechanical and operational factors can cause temperature fluctuations:
Overstocking the unit blocks airflow, preventing even cooling.
Damaged door gaskets allow warm air to seep in.
Faulty thermostats or sensors send incorrect temperature signals.
Frequent door openings, especially during peak hours, allow warm air to enter and strain the compressor.
How to Fix Refrigerator Temperature Fluctuations
Clean the condenser coils using a brush or vacuum every 3–6 months.
Avoid overloading — leave 5–10 cm space for proper air circulation.
Check the door seals for tears or gaps.
Calibrate or replace the thermostat/sensor if readings are inconsistent.

Train staff to minimize unnecessary door openings.
Keep the storage area’s ambient temperature within manufacturer specifications.
Maintaining stable temperatures not only preserves food quality but also ensures compliance with Singapore’s cold chain standards such as SS 668, which sets best practices for chilled and frozen food storage.
Why Are the Door Gaskets and Seals on My Commercial Refrigerator Wearing Out So Quickly?
Door gaskets and seals wear out quickly because they experience constant pressure, temperature changes, and frequent door openings. In busy commercial kitchens, grease, dirt, and cleaning chemicals can also degrade the rubber material. Once the gasket loses its elasticity or forms small cracks, it no longer creates an airtight seal — forcing the compressor to overwork, increasing energy consumption, and compromising food safety.
How to Detect Gasket Wear
You can easily check for gasket problems using the “dollar-bill test” — close the door on a piece of paper and try pulling it out. If it slides out easily, the seal is weak. Other signs include condensation around the door frame, frost buildup near the hinges, or warm air entering the cabinet.
Why It Happens
Frequent door use in high-traffic kitchens wears out seals prematurely.
Harsh cleaning agents break down rubber materials over time.
Misaligned doors or bent hinges stretch the gasket unevenly.
High ambient humidity in Singapore accelerates rubber deterioration.
Improper installation or low-quality aftermarket seals reduce longevity.
How to Fix It
Clean the gasket with mild soap and warm water to remove grease and debris.
Realign the door if it’s sagging or uneven.
Use a hairdryer or heat gun on low setting to soften and reshape minor warping.
Replace torn or cracked seals with OEM-approved gaskets for your refrigerator model.
Lubricate the gasket lightly with silicone grease to maintain flexibility.
How to Extend the Life of Door Gaskets and Seals
Clean seals weekly with a mild detergent — avoid alcohol or chlorine-based cleaners.
Keep door hinges tight and aligned to reduce uneven pressure.
Train staff to close doors gently rather than slamming them.
Inspect gaskets during monthly maintenance checks and replace them every 12–18 months, depending on usage.
Maintain proper humidity control in storage areas to reduce condensation stress on seals.
Properly maintained gaskets keep your refrigerator energy-efficient, reduce compressor strain, and ensure consistent cooling — all of which are essential for maintaining compliance with SFA cold storage standards in Singapore.
Why Is My Commercial Refrigerator’s Compressor Failing or Overheating?
