What Causes A Refrigerator To Make A Popping Noise?

Refrigerator makes popping noises. I have a Samsung refrigerator that can be noisy at times. I hear loud popping sounds coming from the refrigerator at random times. What could be causing the noises in my fridge? I had a Whirlpool refrigerator in the past and I never heard very loud noises. I would like to know if refrigerator popping sounds are normal or do I need to call for service?

What Causes A Refrigerator To Make A Popping NoiseAll refrigerators make noise when operating


The normal operation of your refrigerator will cause some noises and sounds. All refrigerators have parts and components that contract or expand because of changes in temperature. When the defrost heater cycles on and off, sounds such as popping noises can be heard coming from the refrigerator/freezer. These sounds are normal and no cause for concern unless the sound is constant or varying in a strange way. 20 refrigerator sounds


If you believe the refrigerator noises are not a normal common sound, troubleshoot the issue by eliminating the possibility that another component in your refrigerator may be malfunctioning within the fridge.

Use a timer and time how often the noise is heard. If you hear the popping noise 4 times a day at equal intervals its most likely the defrost heater turning ON and OFF. This is normal and is no cause for concern.

  1. Whirlpool refrigerator gave a very loud pop sound and emits smoke/ gas. Not sure if it’s smoke or gas. Switch off the power and look at the back of the refrigerator but it’s not hot. I do not have any inbuilt waster dispenser or ice maker. Any idea what causes it?

    I’ve had my Kenmore refrigerator for a few years. Lately, when I’m in bed at night (the kitchen wall abuts my bedroom wall) I hear the fridge running and when it’s shutting down it makes several popping sounds. Any idea what is causing this and if it’s serious?

  4. My week-old Hisense under counter fridge ( no freezer compartment) RL170D4BC21/W21 is making intermittent popping sounds – 3 times in the last 90 minutes. Is this a malfunction?

    LG Refrigerator not working after power outage
    Power went out, when it came back on my LG refrigerator made a pop noise and won’t come on at all.
    Is there a reset button, if not, what happened and is it fixable?
    It’s less than a year old and I can’t afford to but another one.
    Please inform me on how to fix it, I wouldn’t think it is broken and has to be something simple that I’m just missing.
    Food is ruined so please give me a solution.

    The refrigerator is making a continuous popping sound, every 3-4 seconds. It had been doing this intermittently before, but after some recent power surges, it started again. It has not been making ice for several months, then suddenly it started making ice again. The popping sound started when it starting ice again. I believe it is the ice maker ejector arm. The popping sound is coming from the back of the fridge, upper left side.
