Why Your Aircon Refuses to Start

A dead unit usually has a simple cause, and the cheapest explanations are the most common. Here is the list we work through, cheapest first:

Power supply

A tripped breaker, a switched-off isolator or a dead power point stops everything before the unit even thinks about starting.

Remote or thermostat

Flat batteries, a stuck mode or a dead display means the unit is healthy and never got the message.

Failed capacitor

The capacitor gives the compressor and fan their kick-start. When it dies, the unit has power but will not run.

Worn contactor or board

Older systems, especially units retrofitted into the post-war brick homes here decades after the build, often fail at the contactor or control board first.

Compressor failure

The expensive one, and thankfully the rarest. It usually shows up as a unit at the end of a long life.

How it works

Safe Checks Before You Call

A few checks cost nothing and fix a surprising share of no-start calls. Work through these first:

  1. Step 1: Step 1

    Check the power point by plugging in something else, like a lamp.

  2. Step 2: Step 2

    Look at the switchboard for a tripped breaker and reset it once.

  3. Step 3: Step 3

    Confirm the isolator switch near the outdoor unit is on.

  4. Step 4: Step 4

    Put fresh batteries in the remote and try again.

If the breaker trips a second time, stop. That points to an electrical fault, and repeated resets can turn a small problem into a burnt-out component. Everything past the power point involves wiring or refrigerant, and that is licensed work.

When a Dead Unit Needs Air Conditioning Repairs

Call a technician the moment the basics check out, or the breaker trips again. Summer here stacks consecutive days over 40, and the low ground toward the River Torrens holds heat late into the evening, so a silent unit in February is not a problem you want to sit on.

Our air conditioning repairs team diagnoses first and quotes second, so you know the cost before anyone lifts a tool.

Signs It Is Electrical

A breaker that trips every start, a burning smell or a click with no fan all point to wiring, capacitors or the board. Leave those alone and ring us.

Time to Replace

A unit past fifteen years old that will not start, especially one with a failed compressor, is often better replaced. We will say so honestly rather than sell you another repair, and our replacement page explains how we size a new system.

How it works

How We Get Your Cooling Running Again

The visit follows the same shape every time, because a proper diagnosis comes before any parts get ordered.

  1. Step 1: Test the Supply

    We confirm power is reaching the unit, then check the capacitor, contactor and board in that order.

  2. Step 2: Find the Fault

    Once the cause is clear, we explain it in plain words and give you a fixed quote before any work starts. No hourly rates, no bill shock.

  3. Step 3: Fix and Prove

    Most no-start faults are fixed on the spot because we carry the common parts. We run the system through a full cycle before we leave, and every job sits under our Lifetime Labour Warranty: if a fault occurs due to workmanship, the team returns and fixes it at no cost.

    All refrigerant work is carried out under ARC Licence L162586, the RAC01 full refrigeration and air conditioning licence.

Questions

Aircon Not Turning On FAQs

Can I fix a dead air conditioner myself?

You can safely check the power point, the switchboard breaker and the remote batteries, but anything past that involves wiring or refrigerant and needs a licensed technician.

How fast can you get here?

We cover Klemzig most weeks and our Within-the-Hour Response covers urgent callouts where availability allows, so ring us and we will give you a straight answer on timing.

Is a dead unit always a big repair?

No, plenty of no-start faults turn out to be a failed capacitor, a tripped breaker or a worn contactor, which are among the cheaper repairs on our list.

When is replacement the better option?

If the unit is past fifteen years old, needs repeat callouts or has a discontinued compressor or board, we will tell you plainly that replacement usually costs less.
