In short
Most new refrigerator noises come from something touching something else, not from a failing compressor. On this machine the first suspect is condenser fan hitting dust, a bag or a stray object.
What you observe
- A ticking or chirping from inside the freezer — Something is touching the evaporator fan blade — usually frost.
- A buzz or hum from the bottom rear that comes and goes — The condenser fan or the compressor, and the timing tells you which.
- A rattle that stops if you press on the cabinet — Panel, tray or tubing resonance rather than a component fault.
- NEAR MISS — noisy and also not cooling — Then noise is the symptom and cooling is the fault; the cooling-failure page ranks it properly.
Causes, most likely first on a Simplicity refrigerator
- Condenser fan hitting dust, a bag or a stray object — The condenser fan lives underneath or at the back, where light debris collects and gets drawn in. Ranked first on a Simplicity refrigerator: the fan runs in the dustiest place in the kitchen and collects whatever the floor offers.
- Evaporator fan blade catching frost or a worn fan bearing — A dry fan bearing whines or chirps whenever the compressor runs and goes quiet the moment it stops.
- Cabinet not level, or touching a wall or cabinetry — Out of level, the machine rocks on two feet and every vibration becomes a knock.
- Drain pan vibrating or sitting out of position — The pan under the cabinet collects defrost water and rattles against the frame when it is not seated.
Check in this order, and why
- Pull the cabinet out and look at the fan behind the lower rear cover — Debris on or near the blade is visible immediately.
- Open the freezer and press the door switch in: does the noise start with the fan? — If the noise continues with the door open and the switch released, the fan is not the source.
- Push gently on the top corners and see whether the cabinet rocks — Check the gap behind the cabinet at the same time — contact with the wall is enough on its own.
What an owner can safely check
- With the power off, clear dust and debris from around the condenser fan and coil — Most floor-level rattles stop here, and the coil cleaning helps the cooling as well.
Tools: vacuum, torchAbout 20 min
- Hold the door switch in and listen at the freezer rear panel, then release it and listen again — A noise that tracks the fan exactly is the fan; one that carries on is behind or below the cabinet.
About 10 min
- STOP HERE if the next check needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Disconnect power at the plug or the breaker before opening anything, and give a capacitor time to bleed down before you reach past a board. Nothing sharp goes near an iced evaporator: thin tubing, refrigerant under pressure, no home repair. Refrigerant work is licensed work, so the sealed system is where the owner job ends. Empty the cabinet before you move it.
When to call a technician
Call when the noise is a grinding that worsens, when it tracks the compressor exactly and the mounts look sound, or when a fan is clearly the source and it is behind a panel. A noise alone is rarely urgent; a noise with warmth in the cabinet is. These machines are genuinely repairable and the common parts are generic, so a repair is usually the economic choice unless the sealed system is involved.

What this page does not cover
This is the generalised Simplicity refrigerator page. A family- or model-specific page, where one exists, is linked above and is the more precise answer for your unit. Left out on purpose: part numbers, connector colours, the order panels come off in, and every torque figure — a generalised page cannot be right about any of them.
