Daikin Aircon Repair in Malaysia: Common Faults, Error Codes and What It Costs

An Aircon Hero technician in a bucket hat bends over an open rooftop packaged air-conditioning unit, driving a cordless drill into its panel with trees behind him, the kind of on-site work a Daikin aircon repair call involves.
Quick answer: A Daikin aircon repair starts with a blinking light, a code on the remote, or a unit that is not cold. Aircon Hero is independent, services all major brands including Daikin, and charges RM88 for a non-inverter or RM108 for an inverter wall-mounted diagnostic, as listed on the Aircon Hero price list on 2026-09-06.

What goes wrong most often on a Daikin aircon?

The Daikin faults that bring most repair calls to Aircon Hero are a dirty filter or coil that chokes airflow, a refrigerant shortage from a slow leak, a failed fan motor or capacitor, a blocked drain that drips indoors, and a circuit-board or sensor fault.

Daikin Malaysia's error-code list (2025-09) names the same faults and notes meanings may differ between models.

Daikin code Meaning stated by Daikin What Aircon Hero does
U0 Refrigerant Shortage Leak test, then top-up or leak repair quoted after inspection
A6 Fan Motor Fault Tests motor and capacitor, quotes the part
A5 Freeze-up Protector Checks filter, coil and fan airflow
E6 Faulty Compressor Start Up Checks voltage, capacitor, compressor

What does the blinking light on a Daikin mean?

A blinking operation lamp on a Daikin generally means the unit has stopped itself on a fault. Daikin Malaysia's error-code page explains how to read it: hold the ON TIMER CANCEL or OFF TIMER CANCEL button for 5 seconds until "00" flashes, press repeatedly until a continuous beep, then read the code shown.

Note the code before switching off; an independent Daikin ac repair technician asks for it first.

Daikin aircon not cold but no error code: what should you check first?

When a Daikin aircon is not cold and shows no code, six checks rule out the cheap causes: mode, set temperature, filter, outdoor fan, ice on the pipes, and power. Aircon Hero asks callers to run them before booking a visit.

  1. COOL mode, set below room temperature.
  2. Filter out; if no light passes through, wash it.
  3. Outdoor fan turning, grille clear.
  4. Ice on the pipe: switch off, let it thaw.
  5. Isolator and breaker on; switch off at the isolator before opening any cover.
  6. Read the error code as above.

Still warm? The aircon not cold guide covers the remaining causes.

Should you call Daikin or an independent technician for a Daikin aircon repair?

Both routes are legitimate. Daikin Malaysia runs its own repair service, and its error-code page advises seeking Daikin professional assistance. Aircon Hero is independent, not an authorised Daikin dealer; it services all major brands including Daikin, quotes after diagnosis and before work starts, and covers workmanship with a 1-month warranty.

Prefer Daikin when a major part is still under the manufacturer's warranty. An independent Daikin air conditioner repair service suits out-of-warranty units or an urgent breakdown, with same-day service subject to technician availability. See the aircon repair page and the common aircon faults article.

How much does Daikin aircon repair cost at Aircon Hero?

Aircon Hero charges a diagnostic and troubleshooting fee of RM88 for a non-inverter or RM108 for an inverter wall-mounted unit. The repair is quoted after diagnosis and approved by the customer before work starts. A gas top-up is RM158 for a 1 to 1.5 HP unit, plus RM28 per additional 0.5 HP.

A Daikin inverter ac repair costs more to diagnose. When the fault is dirt, not a part, a basic Daikin aircond service on a wall-mounted unit is RM88 for 1 unit, RM78 each for 2 units, RM68 each for 3 or more units, per the Aircon Hero price list.

Read the code, then book the right visit

Run the six checks, note the code, and decide: a warranty-covered part goes to Daikin; anything else goes to an independent technician. Then book an aircond service every 3 months or an aircon servicing and maintenance plan. WhatsApp +60 18-355 5162 or email [email protected] with the code.

Frequently Asked Questions

A blinking lamp means the Daikin unit has shut itself down on a detected fault and will not cool until it is cleared. Read the error code from the remote; sensor, fan-motor and refrigerant-shortage codes are behind most blinking-lamp calls Aircon Hero attends.

Daikin Malaysia's error-code page (2025-09) says to hold the CANCEL button down for 5 seconds; the display also cancels itself if no button is pressed for 1 minute. Clearing the display does not clear the fault, so note the code first.

Daikin Malaysia lists U0 as "Refrigerant Shortage": the unit has too little gas to cool. Aircon Hero leak-tests before topping up, because gas added to a leaking system escapes again; a top-up is RM158 for a 1 to 1.5 HP unit.

Yes. Aircon Hero services all major brands including Daikin, inverter or non-inverter. An inverter wall-mounted diagnostic is RM108 against RM88 for a non-inverter, because the DC board and variable-speed compressor take longer to test. Parts are quoted after diagnosis and approved before work starts.

Aircon Hero cannot speak for Daikin's warranty conditions, so read your warranty card or Daikin Malaysia's warranty registration terms before an independent repair on a unit still under cover. Aircon Hero's own workmanship carries a 1-month warranty; parts warranties come from the manufacturers.

Aircon Hero recommends a service every 3 months for residential units and every 1 to 2 months for commercial units. Regular Daikin air conditioner servicing keeps the coil and drain clear, which prevents the freeze-up and dripping faults behind most repair calls.
