The short answer
On the MPWFR family, a cabinet that has started making a noise it did not make before usually comes down to cabinet not sitting level or not carrying weight evenly. The quickest way to place it is to rock the cabinet gently at each front corner. Three of the four causes below are owner-checkable in minutes; the last is where a service call starts.
What you observe
- A chopping or ticking noise from inside the freezer — A fan blade catching frost on each turn makes a rhythmic sound that rises and falls with the fan rather than with the compressor.
- A grinding or whirring that rises when the doors are shut — Fan noise is louder with the doors closed on many cabinets, because the door switch lets the fan run only when the door is shut.
- Gurgling or a hiss a few minutes after the cooling stops — That is refrigerant settling in the circuit and boiling off, and on most cabinets it is a normal end-of-cycle sound.
- NEAR MISS: the noise is there and the cabinet is also warm — Noise with lost cold is the cooling page, not this one, and the noise is usually a symptom of the same fault.
Causes, most likely first
- Cabinet not sitting level or not carrying weight evenly — It ranks first because it is the most common cause and the cheapest to rule out: a cabinet with one foot short transmits every compressor vibration into the floor instead of absorbing it.
- Tubing, drain pan or panel touching something it should not — It ranks high on an older roster because the parts that keep those pieces apart are the parts that age: rubber grommets go hard, clips lose grip, and the drain pan starts to buzz on its rails.
- Evaporator fan blade catching ice — It sits behind the cheaper causes only because confirming it means getting into the freezer, not because it is rare on a cabinet of any age.
- Compressor mounts hardened or the compressor itself noisy — The compressor is bolted down on rubber, and rubber hardens with years of heat, so a unit that was quiet when new can hum through the cabinet without anything having failed.
- Body: This page covers the MPWFR family, and the table below lists a single model, so nothing here has to be hedged across variants: the ranking is the ranking for that build. That order is the brand-generic order for this symptom, because nothing in how this line is built moves any of these causes past another.
Check in this order, and why
- Rock the cabinet gently at each front corner — Any movement at all means a foot is not carrying, and that is where the noise is coming from.
- With the unit running, press lightly on each rear panel and the drain pan — A noise that changes or stops under a hand is a contact point, and it is almost always fixable without parts.
- Open the freezer and listen with the door switch held in — A chopping that starts with the fan and stops when you release the switch places the noise at the blade.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. With one configuration in the field, there is no variant that reorders these.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before you reach behind any grille or panel. A condenser fan starts without warning when a control calls for cooling, and a blade that is spinning at the moment your fingers arrive does not care that the cabinet was quiet a second earlier.

When to call a technician
Call when the noise survives levelling, reseating the contents, clearing the rear grille and a full defrost, or when it is clearly coming from the compressor itself rather than from something resting against it. Call sooner if the noise arrived alongside a cabinet that is no longer cooling, because the noise is then a symptom rather than the fault.
