The repair needs to address the cause, not simply clear an alarm or add refrigerant. Restricted airflow, damaged door seals, failed fans and electrical faults can produce similar symptoms but require different work. We are REFCOM F-Gas registered and provide a fixed written quote before work starts. Call 07427 826446 to discuss your fridge, its symptoms and access to your premises. We are open seven days a week, 07:00–21:00.
Restoring Reliable Cooling in Working London Kitchens
In a restaurant kitchen, café or takeaway, the fridge works against heat from cooking equipment, frequent door openings and repeated deliveries. A unit that cools overnight but struggles during lunch service may have inadequate condenser airflow, a weak fan or a door that is not closing properly. Useful checks include comparing the controller reading with an independent temperature measurement, checking the loading pattern and inspecting the condenser. These distinguish a repairable equipment defect from operating conditions that are overwhelming an otherwise functioning cabinet.
London premises often place refrigeration in tight spaces, including basement kitchens and narrow service areas. Boxes against a ventilation grille or equipment pushed too close to a wall can prevent heat rejection. Repair decisions should therefore account for the cabinet’s surroundings as well as its components. After work, checking airflow, door closure and temperature recovery helps establish whether the fridge is cooling properly under the conditions in which it will actually be used, rather than merely showing a lower number on its display.
Refrigeration Circuit Repairs Without Guesswork
The compressor, condenser, expansion device and evaporator must work together to remove heat from the cabinet. Poor cooling can result from a refrigerant leak, a restriction, a failed condenser fan or a compressor that runs but no longer pumps effectively. Low suction pressure alone does not prove that refrigerant is missing; an iced evaporator or restricted airflow can also affect operating pressures. Circuit work should follow checks of airflow, temperatures, electrical operation and the refrigerant specified on the equipment’s rating plate.
Where a leak is confirmed, adding refrigerant without addressing it leaves the underlying defect unresolved. Depending on the repair, circuit work can involve refrigerant recovery, leak repair, pressure testing with oxygen-free nitrogen, evacuation and charging by weight to the manufacturer’s specification. Cabinets may contain fluorinated refrigerants such as R134a or hydrocarbons such as R290. REFCOM F-Gas registration relates to work involving fluorinated gases; flammable hydrocarbon systems require appropriate competence, tools and ignition controls. Refrigerant selection and handling must follow the applicable regulations and equipment specification.
Door, Fan and Drain Faults That Undermine Performance
A damaged gasket can let warm, humid kitchen air enter continuously, increasing compressor running time and encouraging ice around the evaporator. Worn hinges, a distorted door or a faulty closing mechanism can produce the same effect even when the seal looks intact. The appropriate repair depends on whether the problem is the gasket, alignment or surrounding cabinet structure. Evaporator fans also matter: a cabinet can have a cold coil but warm stock if air is not circulating through its intended path.
Water on the floor does not necessarily mean a refrigerant problem. A blocked condensate drain, displaced drain hose, damaged collection tray or failed condensate heater can allow defrost water to escape. Repeated ice formation can also follow a defrost heater, termination sensor or control fault. Simply melting the ice may restore airflow temporarily without fixing its cause. Drain routes, fan clearances and the defrost sequence should be checked as relevant, with attention to nearby electrical components before the cabinet is returned to use.
Electrical and Control Repairs Based on the Actual Fault
A blank display, repeated cycling or a compressor that hums without starting can point to electrical or control problems rather than a failed refrigeration circuit. Possible causes include a defective temperature probe, damaged wiring, a failed relay, a contactor fault or a start component on compressors that use one. Checks may include supply voltage, connections, current draw and comparison of probe readings with measured temperatures. Component replacement should follow evidence of failure rather than an assumption that the controller or compressor must be responsible.
Electrical protection devices must not be bypassed to keep a fridge running. If the unit repeatedly trips its circuit, smells of burning or shows heat damage at the plug or socket, stop using it and isolate it if this can be done safely. A fault may be within the appliance or in the premises’ electrical supply, and that distinction affects the work required. Once repaired, control settings, compressor operation and any relevant defrost functions need checking against the cabinet’s intended operating range.
Protecting Chilled Stock While the Fridge Is Out of Use
For foods subject to chilled temperature control in England, the general legal maximum is 8°C, subject to specific exemptions. The Food Standards Agency recommends setting a fridge at 5°C or below to allow for fluctuations. Some products require stricter conditions under their storage instructions or your food safety procedures. Do not rely solely on the cabinet display when cooling is suspect: its sensor measures conditions at one location and may not represent the temperature of food throughout the cabinet.
Keep door openings to a minimum and move vulnerable stock to suitable working chilled storage where available. Record temperatures and the times at which the problem was noticed, following your HACCP-based food safety procedures. Food safety decisions depend on the product, its temperature and how long it has been outside safe conditions; a successful repair does not make affected food safe again. Avoid loading fresh deliveries into a struggling cabinet, and do not chip ice away with knives or other sharp tools.
Arranging Commercial Fridge Repair Across London
Air Conditioning Installation London covers all 32 London boroughs, the City of London and M25 towns. When you call, explain whether the fridge is in a restaurant, café, pub kitchen, food shop or workplace catering area. Access details matter, particularly at premises with basement stairs, controlled loading bays or restricted delivery hours. Tell us where the cabinet is located and whether it can be accessed without moving other equipment. This helps establish the practical requirements before repair work is arranged.
Have the make, model and serial number ready if the rating plate is accessible without removing covers. Note the displayed temperature, any error code, when the symptoms began and whether the compressor or fans appear to run. Mention previous repairs or recent changes to the cabinet’s position or loading. A fixed written quote is provided before work starts. Call 07427 826446 during our opening hours, seven days a week from 07:00 to 21:00, to discuss the next step.

Frequently asked questions
Why is my commercial fridge running but not getting cold?
Continuous running can result from poor condenser ventilation, a failed fan, an iced evaporator, leaking door seals or a refrigeration circuit fault. Check that accessible ventilation grilles are unobstructed and doors close fully, without removing panels or touching electrical parts. Record the displayed and independently measured temperatures. Turning the thermostat lower will not overcome a mechanical fault and can make it harder to understand the original symptoms.
Does a commercial fridge just need regassing when it loses cooling?
Not necessarily. Refrigerant circulates within a sealed system and is not normally consumed during operation. If the charge is low, a leak or previous incorrect charging needs consideration. Similar symptoms can arise from airflow restrictions, controls or compressor faults. The refrigerant type must be confirmed before circuit work; different refrigerants are not interchangeable, and both environmental rules and flammability risks can affect the repair method.
Can I keep using the fridge while waiting for a repair?
Only if it can maintain the conditions required for its contents and there is no electrical or other safety concern. Check temperatures rather than assuming that compressor noise means effective cooling. If food temperatures are rising, follow your food safety procedures and transfer stock to suitable storage where possible. Stop using equipment that trips repeatedly, smells of burning or has water reaching electrical components, and isolate it safely.
What should I do before the engineer attends?
Make the cabinet accessible and gather its make, model, serial number, error codes and recent temperature records. Tell us about parking restrictions, stairs or controlled access when arranging the visit. Move stock if required by your food safety procedures, but do not dismantle panels or interfere with pipework. Photographs of the display and accessible rating plate can help you relay accurate information when calling about the repair.
