The short answer
The CRRK models put the evaporator fan directly behind the rear freezer panel, so a rattle or a chirp that changes when the freezer door opens is that fan, every time. The door switch stops it; using the switch as a test tells you in seconds what a teardown would take an hour to show.
What this looks like from the kitchen
- NEAR MISS - water running noises with no puddle — Meltwater finding the drain. It is the cabinet working correctly, and chasing it wastes a weekend.
- A rattle that changes if you press on the cabinet side — Panel resonance: the cabinet is passing a normal vibration into a surface that amplifies it.
- A rhythmic ticking that follows the compressor — It starts when the compressor starts and ends when it stops, which places the noise in the machine compartment rather than in the cabinet.
- A chirp or squeal from the back of the freezer that stops when the door opens — The door switch cuts the evaporator fan, so anything that stops with the door is that fan or something it is touching.
- A knock when the cabinet cycles off — Tubing moving against the shell as it cools. Harmless, but it is worth confirming it is tubing and not a loose mount.
What it usually turns out to be
- Evaporator fan motor bearing worn — Real, but it ranks below the frost cause because the same symptom is produced far more often by ice than by wear.
- Compressor mounting grommets hardened with age — A vibration that used to be absorbed is now transmitted to the shell. It is a cheap part and an awkward job, so it is diagnosed carefully before it is chased.
- Cabinet out of level or a foot not carrying weight — Ranks high here precisely because it is invisible: the machine is fine and the floor is the fault, and the noise is a resonance rather than a mechanism.
- Condenser fan obstructed by dust or a shifted shroud — Second, and much more common on cabinets in tight surrounds where the machine compartment never gets cleaned because nobody can reach it.
Check in this order, and why
- Look for frost across the evaporator through the rear freezer panel vents — Do this once the fan has been implicated: frost in the blade path explains the noise and points at defrost rather than at the motor.
- Press each cabinet panel in turn while the noise is happening — A rattle that changes under your hand is resonance and needs no part at all.
- Listen at the back of the machine compartment with the compressor running — Second because it needs you behind the cabinet, but it separates the condenser fan from the compressor by ear alone.
- Note whether the noise tracks the compressor cycle — Anything that starts and stops with the compressor is in the machine compartment; anything that runs continuously is a fan.
Before any panel comes off
Safety
Switch the breaker off before you open anything behind the liner. The sealed system is not an owner-serviceable circuit: refrigerant work is licensed work, and a tube nicked with a screwdriver ends the life of the cabinet.

When this becomes a service call
Call if you find water anywhere near the machine compartment, if the cabinet trips the breaker, or if you smell anything hot. Electrical faults inside a damp cabinet do not wait politely for the weekend.
