The answer first
The usual answer on a Thorkitchen refrigerator is the condenser fan and what has collected around it. The compressor and its mounts is on the list below, and it is the least likely thing on it. Built-in machines change the ranking because the installation is part of the appliance: if yours sits in a run of cabinetry, the enclosure and the connection made behind it fail long before anything inside the cabinet does. Most of what follows is owner-checkable in minutes; the step where that stops is marked rather than left to guesswork.
What you are seeing
- A clattering a few times a day followed by running water — That pattern is an ice harvest and a refill, which is normal.
- A deep hum the machine did not used to make — The pitch and steadiness matter: a hum is isolation, a knock is mechanism.
- NEAR MISS — water is appearing on the floor — A leak has its own causes and its own page. Deal with the water first.
Causes, most likely first on Thorkitchen
- The condenser fan and what has collected around it — This fan is the noisiest thing in a normally-working refrigerator, so it is also the first thing to change when something goes wrong. Ranked first on Thorkitchen: it explains more of these calls than anything below, and it is the cheapest to exclude.
- The enclosure the unit is built into — The cabinet is part of the cooling system on a built-in unit: the air it needs comes through one grille, and a blocked grille produces the same reading on every instrument as a tired compressor. Placed here for what kind of machine this is rather than for a part: the enclosure is not the first thing to suspect here, but it is the thing that turns a small fault into a repeated one.
- The ice maker doing its normal work — This is the cause that costs nothing to rule out and is missed constantly: a clatter a few times a day, always followed by a running-water sound, is a working ice maker rather than a fault. Third: common enough, but the two above are cheaper to exclude and look identical from the front.
- The compressor and its mounts — A deeper note than the machine used to make, steady and unchanging while it runs, usually means mounting rather than mechanism. Ranked last, and the order matters most right here: this is the one item that changes what the repair costs.
What to check first, second, third
- First: Listen at the back low down while the machine is running — It is first because the noise can be matched to the running cycle by ear, with the machine untouched.
- Second: Pull the plinth grille and look at the air path — It comes second because it costs nothing, needs no tools, and settles whether the fault is the appliance or the joinery around it.
- Third: Note whether the noise repeats a few times a day rather than continuously — It comes last because ruling a normal noise in or out prevents a service call for nothing.
The checks you can do yourself
- Unplug the machine, pull it out and clear everything around the fan and coil. Get a second person before you pull the cabinet out or tilt it. — Vacuum the coil and the fan housing, and remove anything that has fallen behind or under the cabinet.
Tools: vacuum, soft brushAbout 25 min
- Clear the plinth or toe-kick grille and vacuum the air path behind it — Lift the grille off, vacuum the dust mat behind it and check nothing has been stored in the space.
Tools: vacuum, soft brushAbout 15 min
- STOP HERE if the next step needs a meter on live terminals — This is where the checks above run out. What is left needs a meter, and a meter needs a technician.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so stop at the sealed system. Never defeat a door switch to keep a fan running, and move a loaded cabinet with two people and a floor protector.
When this becomes a service call
The line is simple: everything above is reachable and reversible, and nothing below it is. Anything on the sealed system — refrigerant, the compressor, the tubing — is licensed work, and a machine that has been opened is a machine that needs a technician. Call sooner if the fault is getting worse rather than staying the same, because a cheap cause left alone is how an expensive one arrives.

What this page does not do is speak for one family or one model. It covers Thorkitchen refrigerators generally, and no family-specific page exists for it yet to send you to — when one is published, this page will link down to it and defer to it. Also absent by choice: part numbers, wiring detail and dismantling order.
