Why does my refrigerator rattle only when the compressor runs?

That timing is useful to record, but it does not by itself show what is rattling or prove that the compressor is the cause. GE lists several sounds associated with normal refrigerator operation, and identifies vibrating dishes and an unsteady refrigerator as possible sources of vibration or rattling. Its guidance does not establish the cause of your specific sound. [S1]

Start with checks that do not require removing panels or reaching into the appliance: note when the noise occurs, look for items touching one another, and see whether the refrigerator appears to rest steadily. Use the exact model’s manual for any leveling guidance. If the noise seems internal or continues after these external checks, arrange service rather than opening it up.

Keep the inspection to places you can see and reach safely. Check whether accessible items on top of or beside the refrigerator are touching it, and whether dishes, containers, or other contents are vibrating against one another or a shelf. GE identifies vibrating dishes as one possible source. [S1] Do not pull the refrigerator out if doing so would strain you, damage the floor, or require disconnecting anything.

For the alcove, note whether the cabinet or nearby objects appear to touch the appliance; do not force the refrigerator into a different position. Check whether it seems stable where it stands. GE guidance points to leveling instructions for the exact model, and a GE manual also lists an unsteady appliance or floor as possible contributors. That manual’s guidance is model-era-specific, so do not treat it as a universal diagnosis. [S1] [S2]

Only consider a leveling adjustment if the instructions for your exact refrigerator model describe it and you can follow them safely. Do not guess which foot to turn or use a generic procedure: the supplied GE guidance points readers to model-specific leveling instructions, and the cited older manual is not universal advice. [S1] [S2]

If you cannot identify the model instructions, or if the refrigerator is difficult to access or does not seem stable, leave the adjustment to an appliance technician. You can still record what you observed. For example, a useful note might say: “Assumption: sound begins shortly after the compressor hum starts and stops when the hum stops. Accessible dishes moved; rattle still present. Refrigerator is in an alcove; contact with surrounding surfaces is uncertain. No panels removed.” Replace those details with your actual observations; do not include anything you have not checked.

Give a concise observation record, not a guessed diagnosis. Include the model number if readily available, where you hear the sound from, when it starts and stops, whether it changes, and which external checks you made. Note any uncertainty, such as “location unclear” or “possible contact with alcove, not confirmed.”

A copyable report: “Refrigerator rattle observation Model: [model number, if available] Sound: [rattle, buzz, or other description] Timing: [when it starts and stops in relation to the hum] Apparent location: [front, side, back, inside, or unclear] Accessible checks: [items moved; visible contact points checked; stability observed] Result: [what changed, if anything] Not checked: internal parts; no panels removed.”

GE notes that refrigerators can make several operational sounds, but that information does not identify the cause of a particular rattle. If your external checks do not explain it, service can assess the appliance. [S1]
