Repair or Replace? When an Old Fridge Isn't Worth Fixing

The repair-or-replace decision on a fridge is usually made wrong, because people compare the repair quote to the price of a new fridge and stop there. The number that actually matters is repair cost plus the running cost over whatever life the old unit has left — and on an old fridge, running cost dominates.

The simple version

Two rules of thumb worth knowing:

• If the repair costs more than about half the price of a comparable new unit, replace it.
• If the fridge is more than about eight years old and the repair is a major component, replace it — almost regardless of quote.

The second rule catches people out because the fridge "still works fine apart from this one thing". On a unit that age, fixing one major component usually just relocates the next failure.

Faults generally worth fixing

• Door seals. Cheap, often DIY, and a failed seal makes the fridge run constantly. Frequently the actual cause of "my fridge isn't cold enough".
• Thermostat or control board on a newer unit.
• Defrost heater or timer. A common, moderate-cost fault behind ice build-up.
• Fan motor. Inexpensive, and often the cause of uneven cooling.
• Blocked defrost drain. Often a free fix — water pooling in the bottom of the fridge is usually just this.

Faults that mean it's over

• Failed compressor. The single most expensive part. On anything over about eight years old, this is the end.
• Refrigerant leak in the sealed system. Finding and repairing a leak in a sealed circuit is labour-intensive and rarely economic on a domestic fridge.
• Corroded or damaged evaporator.
• Cabinet damage or failed insulation. If the foam is degraded or waterlogged, the fridge can never be efficient again.
• Anything on a unit already 12+ years old.

The number people leave out

A fridge from the early 2000s can use two to three times the electricity of a modern equivalent. At Sydney rates that difference is often $150–$300 a year — every year, whether you repair it or not.

So a $400 repair on a fifteen-year-old fridge isn't a $400 decision. It's $400 plus several hundred a year for however long it lasts. Against that, a new efficient unit frequently pays back the difference within a few years and then keeps paying.

Check the energy label or compliance plate for the annual kWh figure, multiply by your rate, and compare to a new model's figure. The gap is usually larger than people expect.

Before you call a technician

Four things that solve a surprising number of "faults" for free:

1. Clean the condenser coils. At the back or underneath. Dust-caked coils can't shed heat, so the fridge runs constantly. This is the most common cause of poor performance and the easiest fix.
2. Check the door seal. Close it on a sheet of paper — if the paper slides out easily, the seal has failed.
3. Check the airflow around it. A fridge jammed into a cabinet with no clearance behind it can't work properly.
4. Check the temperature setting and whether a vent inside is blocked by food.

The garage fridge is a special case

If the fridge in question is a second unit in the garage, the answer is almost always don't repair it. An old fridge in an uninsulated Sydney garage can cost $200–$400 a year to run for very little benefit. Spending money to keep that going rarely makes sense. Full breakdown.

If you're replacing

Sort the old one out on delivery day, not "soon". Once the new fridge is in and cold, the old one migrates to the garage and stays there for years, still plugged in, still costing money.

Some retailers remove the old unit on delivery — usually for a fee, usually only as a like-for-like swap, and only if it's emptied, defrosted and disconnected first. If that doesn't suit, book it separately.

We collect fridges and freezers — $80 for a small–medium unit, $150 for a large one — within 24–48 hours across Sydney, degassed under licence and recycled. You don't need to remove the doors or be home, provided the fridge is outside at the agreed kerbside collection point before pickup. Please arrange safe placement there in advance. Collections run Monday to Friday, 6am–4pm.

Frequently asked questions

Is a call-out fee worth it just to diagnose?

On a unit under about eight years old, usually yes. Over twelve, you're often paying to be told to replace it.

Can I sell an old working fridge?

The second-hand market for old fridges is thin, because the running cost outweighs the purchase saving for the buyer. Free listings move; paid ones often don't.

Do you take working fridges?

Yes. Most of what we collect still runs.

Can you collect the same day my new one arrives?

Yes, on weekdays subject to availability — name the date when you book.
