The short answer
On a Maxximum refrigerator, a cabinet that runs without getting cold is most often a room or a load the cabinet was never rated for rather than a condenser coil blanketed in dust. How hard it is worked and the room around it come first, because a merchandiser is judged by how it copes with a busy warm room. All three checks below are owner work, and not one of them needs a part.
What the owner observes
- The machine never switches off — Continuous running without reaching temperature is the same fault seen from the compressor's side.
- The cabinet is warm and the compressor is clearly running — The machine is working and losing, which is a different fault from one that has stopped.
- A sheet of frost on the rear wall of the freezer — Light frost is normal; a sheet you cannot see the panel through is not.
- NEAR MISS — the cabinet is silent and nothing runs at all — That is a supply or start fault on a different page. A completely dead cabinet is not this.
Causes, most likely first on this brand
- A room or a load the cabinet was never rated for — A cabinet in a garage in summer, or filled at once with warm shopping, is being asked for more than it can give. It is not faulty; it is losing a race it was never entered in. It leads because this cabinet has the least cooling in reserve, so the conditions around it decide the outcome more than its condition does. It stands in a shop or a service area where the ambient temperature swings through the day.
- No clearance around the cabinet, so it breathes its own hot air — Every cabinet needs a gap behind and above to move heat away. Tight to a wall, boxed into a cupboard or wedged beside a cooker, it takes back the air it just heated. It sits here because a tight installation makes every other fault below it worse, so it has to be ruled out early.
- A condenser coil blanketed in dust — The condenser throws the heat away, at the back or underneath behind a grille. Under dust and pet hair it cannot, so the machine runs continuously and still loses ground. It is low only because this cabinet rarely stands anywhere dusty, not because it is hard to check.
The order to check in
- Take the temperature of the room the cabinet stands in — A garage or a conservatory in summer is a different environment, and it changes what the machine can do. First, because it is the likeliest to end the job.
- Try to fit your hand behind and above the cabinet — If it does not fit, the machine is breathing its own exhaust and that has to be fixed first. Second, once that is clean.
- Look at the condenser at the back or behind the base grille — If you cannot see metal through the dust, you have found it. Third, and by now the answer is usually in hand.
The owner-side checks
- Move perishable food to a cool box and stop adding warm items for a day — This is a test rather than a fix: if the cabinet recovers, the load was the problem.
Tools: cool boxAbout 20 min
- Pull the cabinet out and give it a gap behind and above — No tools. Leave it a day before judging whether it worked.
About 15 min
- Unplug the cabinet and clear the condenser coil — Vacuum and a soft brush; pull the base grille off if the coil is underneath.
Tools: vacuum, soft brushAbout 25 min
- STOP HERE and write down what each check showed — A technician arriving with the free causes eliminated fixes rather than repeats your work.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip ice off an evaporator with anything metal: the tubing is thin-walled, and a puncture scraps the cabinet.
When to call a technician
The line is the freezer's rear panel: everything in front of it is owner work and settles most of these faults, and behind it is a service call. On the food: a refrigerator holds food safely at 40 °F (4 °C) or below. On this brand it is designed to be serviced in place, and the common parts are stocked by the trade.
