The short answer
Hisense refrigerators, like most modern units, make more sounds than older ones because fans and compressors run at varying speeds rather than simply on or off. Popping, gurgling and a click before a run are all normal. The sounds that matter are a tick that stops when the door opens, a rattle from the back, and a hum rising alongside a warming compartment.
Causes, ranked for this Hisense refrigerator
- Cabinet unlevel or in contact with a wall or cabinet — Why: Contact transmits ordinary vibration into the room, and a rocking cabinet adds a knock of its own, neither of which involves a failure inside the appliance.
- Loose rear panel, drip tray or tubing — Why: Parts at the back buzz once a fastener works loose, and this is the usual explanation for a rattle that comes and goes with no pattern.
- Evaporator fan striking ice — Why: Frost building where the fan turns makes a tick or scrape that stops the instant the door switch cuts the fan, isolating the fault in one observation.
- Condenser fan obstructed or coils packed with dust — Why: An obstruction rattles and reduces cooling at the same time, so the appliance becomes noisier and warmer together.
- Compressor or its mounts — Why: Last, because compressors are the quietest hypothesis and every cause above imitates one; a rising hum with a warming compartment is the real pointer.
What to check, in order
- open the door while the sound is happening and note whether it stops. — Because: the door switch cuts the evaporator fan, which isolates that cause immediately.
- locate the noise at the front interior or the back of the cabinet. — Because: front means fan and ice; back means condenser, panels and compressor.
- check level and clearance around the cabinet. — Because: contact and rocking explain many complaints and cost nothing to correct.
- measure the compartments if the hum has grown louder. — Because: noise with warmth is a more urgent diagnosis than noise on its own.
Checks you can safely do yourself
- With the noise happening, open the door and note whether it stops immediately. — Tools: none — Time: a minute
- Listen at the front and then behind the cabinet to locate the source before touching anything. — Tools: none — Time: several minutes
- Check the cabinet is level in both directions and that nothing touches a wall, cabinet or neighbouring appliance. — Tools: a spirit level — Time: several minutes
- Put a thermometer in each compartment and read them after several hours to see whether cooling is affected. — Tools: two appliance thermometers — Time: an afternoon, mostly waiting
- Switch off at the breaker and vacuum the condenser area, checking the fan for an obstruction. Stop here: the evaporator fan is behind the interior panel. — Tools: a vacuum with a brush head — Time: the better part of an hour

Safety

Kill power at the breaker before reaching behind the cabinet or removing a grille, and never chip ice off an evaporator with a metal tool, since puncturing a tube releases refrigerant and ends the repair permanently. Empty a loaded cabinet before moving it.
Where the owner fix ends
Levelling, clearing contact, vacuuming the condenser and locating a loose panel are owner work. Call a technician when the noise stops as the door opens, since that is ice at the evaporator fan; when a hum grows as the compartment warms; and when either compartment misses the safe temperatures quoted above.
