Repair or replace: an honest rule of thumb from the bench
People bring us appliances expecting to be told they are finished, and are frequently surprised. They also bring us appliances they hope to save that genuinely cannot be. The line between the two is more predictable than it looks.
The rough economic rule
If a repair costs more than about half the price of an equivalent new unit, and the appliance is past the midpoint of its expected life, replacement is usually the better decision. Below that, repair.
The rule needs two adjustments. First, an appliance whose failure was caused by neglect — scale, blocked vents, a worn seal — will fail again unless the habit changes, so the calculation should include that. Second, a repair that restores a machine to full working order is worth more than one that patches a symptom.
Nearly always worth repairing
Blender jug seals and blade assemblies
The single most common “dead” appliance we see. A blender leaking from the base almost always needs a gasket, occasionally a blade assembly. Both are cheap and neither needs tools beyond a hand. Check whether the assembly unscrews before assuming otherwise.
Scaled elements
Kettles, coffee makers and steamers that have become slow, noisy or erratic. Descaling is a consumable and an hour, and it restores the machine completely unless the element has already failed.
Power cords and plugs
A frayed cord at the strain relief is a fire risk and a straightforward replacement on most appliances. Do not tape it and continue.
Carbon brushes on universal motors
Found in some mixers and larger machines. Brushes are consumable by design and a motor sparking or losing power often just needs them.
Belts and drive couplings
In stand mixers and food processors there is often a plastic coupling designed to shear before the motor does. That is the part doing its job, and it is a few dollars.
Usually not worth repairing
Worn non-stick coatings
Cannot be re-coated domestically, and commercial re-coating exceeds the replacement cost. Replace.
Burnt-out sealed motors
In most small appliances the motor is a sealed assembly costing a large fraction of the retail price, and the labour is significant. On a mid-priced blender or food processor this is the end.
Cracked jugs and bowls for discontinued models
The repair itself is trivial — you fit a new jug — but if the jug is not made any more there is nothing to fit. Worth checking parts availability before you invest anywhere else in the machine.
Warped pan bases
A base that no longer sits flat cannot be corrected and will never work properly on a ceramic or induction hob.
Any damage to insulation or earthing
Not a cost question. An appliance with compromised electrical safety goes out of service.
What to check before you decide anything
- Is it the appliance or the circuit? A machine that trips a breaker may be fine on a different circuit — kitchen rings get overloaded easily.
- Is there a reset? Many motors have a thermal cut-out that resets when cool, and many machines have an interlock that stops them running if a lid is not seated. Both look like total failure.
- Is it under warranty? Worth checking before opening anything, because opening it usually ends the warranty.
- Are parts still made? A five-minute search decides whether a repair is even possible.
Buying with repairability in mind
If you would rather not have this decision often, the features that predict a long life are unglamorous:
- Blade assemblies and seals that unscrew.
- Published spare parts, especially jugs, gaskets, pads and filters.
- Fasteners rather than glue and ultrasonic welds.
- A manufacturer that has kept a range in production for years rather than refreshing the model annually.
None of these appear in advertising, and all of them are visible in a specification if you look.
Where we stand
Repair is the older half of this business, and it shapes what we put on the shelf. Where a product we list has a replaceable seal, filter or pad, the listing says so. If you have something that has stopped working and you are not sure which side of the line it falls on, bring it to the Mission Gorge Road counter — telling you it is not worth fixing costs us a repair and saves you a wasted one.
Common questions
What is the most commonly wasted repair?
Blenders thrown away because they leak. It is nearly always the gasket in the blade assembly, and if the assembly unscrews it is a few dollars and two minutes.
Is it worth repairing a burnt-out motor?
On most small appliances, no. The motor is usually a sealed assembly costing a large fraction of the retail price, and the labour is significant on top of that.
How can I tell if a machine will be repairable in five years?
Look for blade assemblies and seals that unscrew, published spare parts, screws rather than glue, and a manufacturer that keeps ranges in production rather than refreshing models annually.
