The Eight Common Problems a Refrigeration System Experiences

Owing to keeping food items fresh for a prolonged period, a refrigerator is rightly considered most significant household appliance. When you rigorously use and do not pay much attention towards maintenance, this complex system can develop several problems like faulty motor, insufficient current, coolant shortage, defective thermostat, etc. Learn more by checking out below-mentioned pointers right away.


  • When fridges are switched on, capacitor present inside triggers compressor, and starts entire refrigeration cycle. In case a capacitor goes bad somehow, it would stop all kinds of function.
  • One of the most common reasons due to which electronic items including a refrigerator suffers is insufficient current. You can measure total voltage of outlet using a tester device or multi-metre.
  • According to experts carrying out cool room repairs Melbourne, a defective thermostat cannot unfortunately transmit signals to capacitor, thus, preventing your refrigerator from turning on.


  • A fridge with not enough coolant can never operate properly. Coolants circulate through evaporator coils, and sends cold air to food section. For refilling the said substance, please rely upon a professional.
  • High pressure gas is continuously converted into high pressure liquid, which forces condenser coils to dissipate excess heat. When covered with dirt and dust, this entire procedure would not take place efficiently.


Few ways to clean refrigerator coils include:


  1. Scrape larger clumps of grime only with soft-bristled brush otherwise you might end up damaging outer surfaces. A flashlight lets you see more clearly.
  2. Attach narrow nozzle to vacuum cleaner and very carefully suck out dirt from in between.
  3. Cleaning coils once a year is enough but if you have pets, try doing it more frequently.


  • A compressor is perceived as heart of refrigeration systems without which they would completely shut off. Scrubbing the said part thoroughly and lubricating it can most surely resolve such issues.


  • Fridges would not start under any circumstance in case their motor is defective. Problems associated with breakages and heat can pave way for more disastrous consequences, compelling you to invest in something brand-new.


  • Finally, yet importantly, water accumulating under your refrigerator is a distinct sign of congested defrost drain. Food particles and other debris block a drain’s hose, leading to ice build-up, and later leakage. Flushing with warm water might help to a great extent.



On experiencing any of the eight problems stated above, you must schedule appointment with a technician immediately. Among diverse options readily available, I personally believe the ones offering Melbourne refrigeration repairs services to be best. They also install and maintain cool rooms, slushy machines, ice makers, etc. for more than twenty years. Now isn’t that simply amazing? Conduct thorough research as well as seek specialised recommendations before arriving at a decision.
