The answer first
Start with the condenser fan and what has collected around it: on a Tehanld refrigerator showing a noise that was not there before, that outranks everything else here, and the evaporator fan catching frost comes a long way behind it. Compact and undercounter machines change the ranking because they are put where there is room rather than where there is air: if yours is pushed into a niche or stands on a countertop, clearance and the hookup outrank the internals. Work down the order rather than across the list — the ranking is the page, and the cheapest answer arrives first.
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 rattle or buzz that starts and stops with the cooling — A noise tied to the running cycle is coming from the fans or the compressor area.
- 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 Tehanld
- 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. A rattle that starts and stops with the compressor is describing it directly. Ranked first on Tehanld: it explains more of these calls than anything below, and it is the cheapest to exclude.
- A loose drain pan or a rattling cover — A buzzing that stops if someone leans on the back of the machine is almost always a panel, a pan or a cover rather than a component. Ranked second — less common than the cause above, and the one most often mistaken for something expensive.
- The cabinet touching something — A machine pushed fully back until it touches the wall, a pipe or the adjacent unit transmits every vibration it makes into the building. Ranked third because it needs the two above cleared before any reading from it can be trusted.
- The evaporator fan catching frost — This is the noise worth taking seriously: a fan striking ice means the defrost system is not keeping up, so the noise is an early warning of a cooling fault rather than a nuisance on its own. Bottom of the list on purpose — putting the expensive candidate last is what stops a cheap fault being paid for as one.
What to check first, second, third
- First: Listen at the back low down while the machine is running — It leads the order because the noise can be matched to the running cycle by ear, with the machine untouched.
- Second: Press gently on the rear panel while the noise is happening — It comes second because the same access answers both, and because a hand on the panel identifies it instantly.
- Third: Pull the machine forward a hand-width and listen again — It is last here because moving the machine is free and the answer arrives immediately.
What an owner can safely check
- Unplug the machine, pull it out and clear everything around the fan and coil — Vacuum the coil and the fan housing, and remove anything that has fallen behind or under the cabinet.
Tools: vacuum, soft brushAbout 25 min
- Pull the machine clear of the wall and anything behind it — Leave a hand-width of air at the back and check that no pipe, cable or cabinet side is touching the cabinet.
About 10 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 owner side ends at the checks above: no tools, no panel off, no meter. 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 cover
Read this as the class-level answer for Tehanld refrigerators rather than as a page about one product line. Nothing narrower is published for this brand and appliance yet, so there is nothing to link down to; once there is, that page takes precedence over this one. Deliberately absent: part numbers, torque figures and wiring colours.
