The short answer for RMRT models
Start by deciding whether the RMRT noise is continuous, intermittent or periodic, because each maps to a different group of causes. Continuous means something is running or resonating; intermittent means something is being struck; periodic means a control is switching. That split does more work than any single check below it.
What the owner sees
- A gurgle or a boiling sound after the machine stops — Refrigerant equalising through the tubing. It is normal and is on this list so it can be ruled out rather than chased.
- Opening the door makes the noise stop — The door switch cuts the evaporator fan, so anything that stops with the door belongs to it.
- A single knock when the machine starts or stops — The compressor moving on its mounts as the load comes on or off.
- A click or a clunk every few minutes — Regular, brief, and unrelated to whether the door is open — a switching noise rather than a mechanical one.
- NEAR MISS — the noise arrived and the cabinet stopped getting cold — A fan that has stopped is both quieter and warmer; that combination belongs with the cooling article rather than this one.
Causes in likelihood order on this model group
- Drain pan loose, warped or resting off its bracket — The pan sits over the compressor where it is both hot and in the vibration path. On RMRT this is where to start, because the alternative first checks all need the cabinet moved or a panel off and this one does not.
- Condenser fan blade striking debris, or its bearing dry — The condenser fan lives at the bottom of the cabinet where paper, dust and pet hair collect. Second: this is the part on the list that actually wears, so it climbs the ranking as a cabinet ages and drops on a machine that is still new.
- Cabinet touching a wall, a counter or another appliance — Anything the cabinet touches becomes part of the instrument. A unit set into a recess or pushed against a dishwasher transmits its normal running noise into a much larger surface, and the complaint is a machine that suddenly got loud without anything failing. Ranked third here, because the two causes above it are both quicker to settle and more often the answer on a cabinet of this size.
What to check first, second, third
- The order and the reason for it — Levelling and clearance are free and reversible; a fan or a pan needs the machine isolated and moved. Doing the free half first is the whole of the method.
- Look at the pan with the machine isolated — It should sit square and hold still when you press it. A pan that moves under a finger is the rattle.
- Isolate the machine and turn the condenser fan by hand — It should spin freely and stop smoothly. Grinding or a catch names the part.
- Pull the cabinet clear of everything it touches — Even a finger's width of air changes the sound if contact is the cause.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and on a refrigerator the compressor circuit stays live for as long as the plug is in. Leave the door switch wired exactly as it is: it cuts power to the evaporator fan so that a blade is not turning while your hand is past the panel, and defeating it is the one shortcut that turns a nuisance repair into an injury.

When to call a technician
The honest limit is the rear panel. Behind it are components that need testing rather than looking at, and on a cabinet this size they sit close enough together that a probe in the wrong place breaks something that was working.
