If your fridge is suddenly using more electricity, it’s usually because it’s working harder than it should. Dirty condenser coils, worn door seals, poor ventilation, failing components or a hidden cooling fault can all increase power consumption. Selective Fridges helps Perth homeowners diagnose these issues before they become expensive repairs or higher energy bills.
Why Is My Fridge Suddenly Using More Electricity?
A refrigerator should use a fairly consistent amount of electricity throughout the year. While Perth’s hot summers can naturally increase energy consumption, a sudden jump in your power bill may indicate that your fridge is no longer operating efficiently.
At Selective Fridges, we often investigate calls from customers who have noticed higher electricity bills, only to discover their refrigerator has been working continuously to compensate for an underlying fault.
The sooner the cause is identified, the more likely it is that a relatively simple repair can restore the fridge’s efficiency and prevent unnecessary wear on expensive components.
What Causes a Fridge to Use More Electricity?
Modern refrigerators are designed to cycle on and off as they maintain the correct temperature. If the compressor is running almost constantly, electricity usage will increase.
Some of the most common causes include:
- Dirty condenser coils reducing heat transfer
- Damaged or worn door seals allowing warm air inside
- A faulty thermostat causing excessive cooling cycles
- A failing evaporator fan
- Blocked internal air vents
- Ice build-up restricting airflow
- A compressor beginning to wear
- Refrigerant leaks reducing cooling efficiency
- Poor ventilation around the fridge
- Frequent door opening during warmer weather
Each of these issues forces the refrigerator to work harder, increasing both energy consumption and long-term wear.
Signs Your Fridge Is Working Too Hard
Your refrigerator may be consuming more electricity if you notice:
- The compressor running almost constantly
- The outside of the cabinet feeling unusually warm
- Food taking longer to cool
- Ice cream becoming softer than usual
- Increased motor noise
- Higher quarterly electricity bills
- Excessive heat behind or underneath the fridge
These symptoms often appear gradually, making them easy to overlook until the power bill arrives.
A Common Repair We See
One of the simplest repairs we regularly carry out is replacing worn door seals.
Many customers don’t realise that even a small gap in the seal allows warm, humid Perth air to enter the refrigerator. Every time this happens, the compressor has to work harder to remove that extra heat and moisture.
In many cases, replacing damaged seals or correcting a door alignment issue significantly improves efficiency and reduces unnecessary compressor run time.
Before You Call for a Repair
There are several quick checks you can perform before arranging a service visit.
A Five-Minute Check You Can Try
Take a few minutes to inspect the following:
- Check that the doors close firmly without resistance.
- Inspect the rubber seals for cracks, gaps or mould.
- Ensure nothing inside the fridge is preventing the doors from closing fully.
- Pull the fridge slightly away from the wall and make sure there is adequate ventilation.
- Vacuum dust from accessible condenser coils if your model allows safe access.
- Confirm the temperature settings haven’t been accidentally changed.
If the fridge still appears to be running constantly after these checks, a professional inspection is recommended.
Does Perth’s Climate Affect Electricity Usage?
Yes.
Perth experiences extended periods of high temperatures, particularly during summer. On hotter days, every refrigerator has to work harder to remove heat from inside the cabinet.
However, seasonal increases should be relatively modest.
If your electricity usage suddenly jumps well beyond normal seasonal changes, it’s often an indication that something inside the refrigerator requires attention.
Is an Older Fridge Always Less Efficient?
Not necessarily.
Many quality refrigerators continue operating efficiently for well over a decade when properly maintained.
The bigger issue is neglected maintenance or failing components.
A well-maintained older fridge can often outperform a newer appliance that has blocked airflow, damaged seals or unresolved cooling faults.
When Should You Arrange a Professional Inspection?
If you’ve ruled out simple maintenance issues but your fridge continues running almost constantly, it may be time for a professional diagnosis.
Early detection can often prevent:
- Compressor failure
- Fan motor damage
- Food spoilage
- Increased electricity costs
- More extensive repairs later
Identifying the cause early is usually the most cost-effective solution.

Frequently Asked Questions
Why is my fridge suddenly costing more to run?
A sudden increase in electricity usage often indicates that the compressor is working harder because of poor airflow, worn door seals, cooling faults or failing components.
Can dirty condenser coils increase electricity usage?
Yes. Dust and debris reduce the coils’ ability to release heat, forcing the compressor to run for longer periods.
Is it normal for my fridge to run constantly in summer?
It will run more often during Perth’s hotter months, but continuous operation may indicate an underlying issue that should be inspected.
Can replacing the door seals save electricity?
Yes. Properly sealing doors prevent warm air entering the refrigerator, reducing compressor run time and improving efficiency.
Is it worth repairing an inefficient fridge?
In many cases, yes. Resolving efficiency issues early is often far less expensive than replacing a quality refrigerator.
