The short answer
Noise from the G family is usually one of three rotating parts or the cabinet itself resonating, and which one it is can be told from where and when the noise happens. That ordering is specific to how this platform is built and it is not the order the brand-generic page uses.
What you observe
- A rattle against the wall or a cabinet side — The unit is transmitting normal vibration into the surroundings and needs clearance, not repair.
- Clicking or a repeated tick every few minutes — A start relay or a defrost timer, and the interval is the clue.
- A gurgle or trickle after the unit stops — Refrigerant settling. It is normal and needs nothing done about it.
- A bang or crack from inside the cabinet — Plastic liner expanding and contracting through a defrost cycle, which is normal on most cabinets.
- NEAR MISS - noise plus a cabinet that is warming — Read the cooling page as well; a noisy fan that is failing takes the cooling with it.
Causes, most likely first on G
- Circulation fan blade fouled by frost or an item — Ranked first on the G family: these cabinets carry more than one fan, so identifying which compartment the noise comes from is the whole diagnosis. The order below follows the air path rather than the refrigeration circuit, which is a family property and not a model one. What moves against the brand-generic order is lower down: condenser fan or a loose fan shroud sits above start relay, defrost timer or a solenoid clicking here, because this family is a single build with fixed access points.
- Cabinet contact and levelling — Second: a cabinet that has moved, settled or lost a foot transmits the vibration it has always made straight into whatever it is touching.
- Condenser fan or a loose fan shroud — Third: the condenser fan runs in a confined vented space where debris collects against the blade.
- Start relay, defrost timer or a solenoid clicking — Fourth: the control gear on a built-in is behind a fixed panel, so the tick is heard without the source being visible.
- Compressor mounts or compressor wear — Last: last, and it means the cabinet comes out of its housing to reach anything.
Check in this order, and why
- Open the door and listen for the noise to stop — The circulation fan is switched by the door, so this splits the fault in one move.
- Empty the cabinet and run it briefly — It rules out packages resting against the rear wall, which is a common and free finding.
- Time the noise against the compressor cycle — Noise that begins and ends with the compressor is a different fault from noise that runs constantly.
- Look behind the rear panel for frost touching the fan — Do this last, because it needs the cabinet emptied to see properly.
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. Refrigerant work is licensed work, so leave the whole sealed system to a licensed technician, and call at once if you see oil at the compressor or smell burning.
When to call a technician
Call once the unit is level, clear of its surroundings and the noise persists from inside, because a fan or a relay change on this family means a panel comes off with the cabinet live.
