What this usually is
The usual answer on this unit is a frosted-over evaporator and a stalled defrost cycle; a condenser coil choked with dust and pet hair is the runner-up. Both of those are cheap. The sealed system is last on the list for a reason. The first two checks below need no tools and no panel off; the cause at the bottom of the list is a service call.
What you are looking at
- Frost builds as a sheet on the freezer back wall — Not the usual light dusting, but a solid layer over the panel.
- NEAR MISS: it cools but leaks water onto the floor — That is a drain fault. Read the water-leak page for this unit instead.
The ranking: most likely cause first
- A frosted-over evaporator and a stalled defrost cycle — Ice builds on the evaporator until air can no longer pass through it. The unit keeps running and keeps making cold, but none of it reaches the cabinet. First, and the whole order below follows from it: the defrost system stalls long before it fails outright, so the ice builds quietly over weeks and what the owner notices is the warmth, never the frost.
- A condenser coil choked with dust and pet hair — The coil is how the unit sheds heat. Second: it is the maintenance job nobody is told about at purchase, and it produces exactly this symptom without ever making a noise.
- A sealed-system or compressor fault — A refrigerant leak or a failing compressor gives the same warm cabinet as everything above it, which is exactly why it is diagnosed last and not first. Last on purpose: it is the least common cause on this list and the only one that is not an owner fix, so checking it first only ever wastes money.
Check in this order, and why
- Look at the freezer rear panel for a sheet of frost — This separates an airflow fault from a cooling fault before any tool comes out.
- Pull the unit out and look at the coil at the back or behind the kick plate — Dust here is the cheapest cause on the list and the easiest to rule out.
- Feel whether the condenser coil is warm along its length — Only worth doing once everything above is clean, and only a technician can act on it.
The checks you can make yourself
- Empty the freezer, switch the unit off at the wall and leave both doors open until it is fully thawed — If cold returns afterwards and then fades again over days, the defrost system is your cause.
About 45 min
- Unplug the unit, take off the kick plate and clear the condenser coil and its fan — A vacuum and a soft brush are enough. Do not bend the fins.
Tools: a vacuum, a soft brushAbout 25 min
- STOP AT THIS POINT if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.
Before you open anything
Safety
Switch the refrigerator off at its breaker, or unplug it, before any panel or kick plate comes off. A capacitor can hold a charge after the power is off, and the compressor circuit is live the whole time the unit is plugged in. Leave the door switches exactly as they are: they cut the fan on purpose. Nothing on the sealed system is owner work, because refrigerant is licensed work.
The line between a fix and a service call
Call once the checks above come back clean, or the moment the fault is on the sealed system: refrigerant is licensed work and the tools for it are not owner tools. Call sooner if you smell burning, see oil around the compressor, or the unit trips a breaker.

This page covers the Vitara Forte refrigerator as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: wiring colours, board part numbers, refrigerant charge figures and any sealed-system procedure, all of which differ by family and belong on the page for that family.
