What you are actually seeing
- A vibration you can feel through the floor
- A hum that rises and falls with the cooling cycle
- A rattle that changes when you press on the cabinet
- Not this fault: A hum that continues with the machine unplugged
Ranked causes on a Conserv freezer
- Evaporator fan clipping frost on a frost-free upright — Ranked here because: with no ice maker in the cabinet the defrost drain is the only water path, so any water at all points at it
- Cabinet not level or not sitting on all four feet — Ranked here because: these cabinets are frequently built into cabinetry that does not give them the clearance the platform assumes
- Cabinet touching a wall, a shelf or another appliance — Ranked here because: a coil that cannot reject heat produces every symptom of a failing system while nothing has actually failed
- Loose rear panel, drain pan or lid hinge — Ranked here because: this is a wear part with a service life rather than a component that fails at random
- Contents or baskets vibrating against the liner — Ranked here because: how the machine is loaded and dosed changes its behaviour more than most owners expect
- Condenser fan blade fouled or bearing worn — Ranked here because: the condenser fan is what lets the machine reject heat at all
What to check, and in what order
- Unplug the cabinet and clear dust from the condenser coil and the condenser fan blade
- Place the sound: inside the cabinet, at the back, or at the base
- Press each corner of the cabinet in turn and watch for rocking
- Pull the cabinet clear of walls, shelving and neighbouring appliances
Steps you can safely do yourself
- Press each corner of the cabinet in turn and watch for rocking — Tools: none — Estimated time: a few minutes
- Pull the cabinet clear of walls, shelving and neighbouring appliances — Tools: none — Estimated time: a few minutes
- Move the contents and the baskets away from the liner and listen again — Tools: none — Estimated time: a few minutes
- Rest a flat hand on the rear panel and on the drain pan while the cabinet runs — Tools: none — Estimated time: a few minutes
- Unplug the cabinet and clear dust from the condenser coil and the condenser fan blade — Tools: vacuum with a crevice tool, coil brush — Estimated time: about twenty minutes

When to call a technician
the noise is coming from the compressor or the sealed system the evaporator fan is icing repeatedly, because that is a defrost fault rather than a fan fault the compressor is clicking without starting and the cabinet is warming
