A Hitachi refrigerator that’s suddenly making noise — clicking, buzzing, or a low hum that wasn’t there before — usually isn’t a reason to panic, but it’s worth identifying the sound before it turns into a bigger fault.
What Different Noises Usually Mean
- Clicking every few minutes — often the compressor’s start relay engaging and disengaging, which is normal in small doses but frequent clicking without the compressor actually starting can mean a failing start capacitor.
- Buzzing from the back — usually the compressor itself, and can indicate it’s working harder than normal, often linked to low refrigerant or a struggling condenser fan.
- Rattling — frequently just loose items on top of the fridge or a slightly unlevel unit vibrating against a wall or cabinet, rather than an internal fault.
- A rhythmic whirring that gets louder — typically the evaporator or condenser fan motor bearing wearing out.
Simple Checks Before Calling for Service
- Pull the fridge away from the wall (if possible) and check it’s sitting level using the adjustable feet — an unlevel fridge vibrates and transmits noise into the floor and nearby cabinets.
- Check nothing on top of the fridge is vibrating against the ceiling or a cabinet above it.
- Vacuum the condenser coils and fan area — dust buildup makes fan motors work harder and louder, especially relevant given how much airborne dust UAE homes deal with.
- Note when the noise happens — during the compressor cycle, constantly, or only when the door opens — this detail speeds up diagnosis significantly.
A UAE Climate Note
Hitachi refrigerators run more continuously in UAE households due to higher ambient kitchen temperatures, which means components like fan motors and compressor relays accumulate wear faster here than in cooler climates — a noise that would be an early warning elsewhere often needs attention sooner here.
When to Call a Technician
If the noise is new, gets progressively louder over days, or is accompanied by the fridge not cooling as well as before, it’s worth having it checked before a fan motor or compressor issue leads to full cooling failure and spoiled food.

Frequently Asked Questions
Why is my Hitachi refrigerator making noise?
Clicking can indicate a failing start relay, buzzing often points to the compressor working harder than normal, and a rhythmic whirring usually means a worn fan motor bearing.
How can I reduce noise from my Hitachi refrigerator?
Check the fridge is sitting level using the adjustable feet, make sure nothing on top is vibrating, and vacuum the condenser coils and fan area.
When should I call a technician for a noisy Hitachi refrigerator?
If the noise is new, getting louder over days, or paired with reduced cooling, it should be checked before a fan motor or compressor fault causes full cooling failure.
