In short
A refrigerator that has started making a noise is usually rattling rather than dying. The ranking here puts cabinet not level, or touching a wall or cabinetry first, and the compressor near the bottom, because compressors rarely announce themselves.
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 — the noise is water running behind the panel — That is normal fill and drain, and if water is appearing on the floor the water-leak page is the right one.
Causes, most likely first on a Shanhua Hongyuan (Shandong) Trading Co., Ltd refrigerator
- Cabinet not level, or touching a wall or cabinetry — Out of level, the machine rocks on two feet and every vibration becomes a knock. Ranked first on a Shanhua Hongyuan (Shandong) Trading Co., Ltd refrigerator: it is free to check, free to fix, and the commonest reason a quiet machine became a loud one after being moved.
- Refrigerant tubing or a wiring loom resting against the cabinet — Copper lines at the back are meant to stand clear; where one has been pushed against the frame it buzzes.
- 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.
- 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
- Push gently on the top corners and see whether the cabinet rocks — Any rock at all means the feet need adjusting.
- Look at the rear of the cabinet for tubing that touches the frame or another line — Lines should have air around them; a contact point is the noise.
- Pull the cabinet out and look at the fan behind the lower rear cover — Check the blade turns freely by hand with the power off.
What an owner can safely check
- Level the cabinet on its feet and pull it far enough forward that nothing touches the wall — A cabinet standing square on all four feet with clear air behind it loses most of its noise.
Tools: spirit level, adjustable spannerAbout 20 min
- 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
- 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
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as you found it. Never take a knife, a screwdriver or a heat gun to frost on an evaporator: the tubing behind it is thin, pressurised, and a puncture ends the appliance. Empty a loaded cabinet before you move it.
When to call a technician
The line is simple: reseating, levelling and clearing debris are owner work, and anything requiring the freezer rear panel or the lower deck to come off is not. Call sooner if the cabinet has also stopped holding temperature. Service networks for trading-company nameplates are effectively non-existent, so use an independent technician and expect generic rather than branded replacement parts.

What this page does not cover
This page covers the Shanhua Hongyuan (Shandong) Trading Co., Ltd refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is linked above and it is the better answer — read it first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under one nameplate.
