Humming, gentle gurgling, occasional cracking and a click when the compressor starts or stops are normal fridge sounds. Rattling usually means the fridge isn’t level or something is touching it. Grinding, squealing or a fan that scrapes points to a worn fan motor or ice around the fan. Repeated clicking with no cooling, or loud knocking from the back, points to the start relay or compressor and needs a technician.
Fridges are never silent. They hum, click and gurgle all day, and newer inverter models change their sound as the compressor speeds up and slows down. The trick is knowing which noises are normal and which mean something is wearing out. This guide helps you tell the difference, and shows when it’s time for fridge repair in Dubai.
Samsung’s UAE support page lists several normal sounds: gas moving through the pipes during cooling, interior parts expanding and contracting as temperatures change, the compressor running or shutting off, and the ice maker filling with water or dropping ice into the bucket. These sounds are part of normal operation and don’t need a repair.
| Sound | Usually means | Normal? |
|---|---|---|
| Low hum | Compressor running | Yes |
| Gurgling or bubbling | Refrigerant moving through the pipes | Yes |
| Cracking or popping | Plastic parts expanding and contracting | Yes |
| Single click | Compressor or thermostat switching on or off | Yes |
| Sizzling | Defrost water dripping onto the heater | Yes |
| Rattling | Fridge not level, loose drain pan or items on top | Easy fix |
| Grinding or squealing | Worn fan motor or ice touching the fan | No |
| Repeated clicking, no cooling | Start relay or overload protector failing | No |
| Loud knocking from the back | Compressor or its mounts | No |
Most frost-free fridges have two fans: one inside the freezer and one by the compressor at the back. When a fan motor’s bearings wear, it squeals or grinds, often louder when the freezer door is open. If ice builds up around the freezer fan, the blades scrape against it with a rattling or ticking sound. Samsung also notes that frost can block the fan and cause rattling. Our guide on why your freezer freezes up solid explains how this ice forms.
If the fridge clicks every few minutes, hums briefly and then goes quiet without cooling, the compressor is trying to start and failing. The start relay or overload protector is the usual cause, and sometimes the compressor itself. This is common after power dips and needs a technician quickly, because the food is warming. Our freezer repair near me service treats this as a priority call.
Unplug it if you smell burning or the back of the fridge is too hot to touch near the compressor. Don’t keep restarting a compressor that won’t run.
High summer temperatures make compressors run longer and harder, so worn parts get louder sooner. Dust on the condenser coils adds to the strain, and fridges kept in garages or store rooms without AC work even harder. Fridges squeezed into tight kitchen spaces also pass vibration into cabinets and walls. Many LG and Samsung models use inverter compressors that ramp up and down, which sounds different from older fridges but is normal. Our LG fridge repair Dubai team knows these sounds well.

Yes. A steady low hum is the compressor running. It should stop and start through the day.
Plastic parts expand and contract as the temperature changes, especially during defrost. It’s normal.
The compressor is trying to start and failing, usually because of the start relay, the overload protector or the compressor.
Usually it isn’t level, something is on top, or the pipes or drain pan are touching or loose.
A worn fan motor or ice touching the fan blades. A technician should check it.
Not usually, but their sound changes as the compressor speeds up and slows down, which is normal.
New fridges can sound louder for the first day or two while they cool down for the first time. If the noise stays loud after that, check the levelling.
