Panasonic not cooling, leaking, or flashing its timer light? Here are the faults a Panasonic typically develops, how the blinking light signals them, and what a fair repair costs in the Klang Valley.

Panasonic has been a household aircon name in Malaysia for decades, from older non-inverter wall units still soldiering on in many homes to the current inverter range with its air-purifying features. That long history matters for repair: parts are widely available, technicians know the units well, and the faults tend to be predictable wear rather than mysteries. This guide sets out the problems a Panasonic typically develops, the way it signals a fault — a blinking indicator light rather than a numeric screen — and what a fair repair costs, so you can read a quote clearly. It complements our general aircon repair hub, which routes any brand by symptom, and our Daikin repair guide if you are comparing brands.
Panasonic units, old and new, tend to bring the same short list of complaints:
| Symptom | Usual Panasonic cause | Typical fix |
|---|---|---|
| Weak or no cooling | Clogged coil, or low gas from a leak | Chemical wash, or leak find-and-repair |
| Timer / power light blinking, unit stopped | Protection trip — sensor, fan or board | Read the blink pattern, diagnose |
| Water dripping indoors | Blocked drainage tray / pipe | Clear & flush drainage |
| Older unit won’t start | Aged start capacitor | Capacitor replacement |
| Rattling or squealing indoor unit | Dirty or worn blower fan / bearing | Clean or replace fan / bearing |
| Loss of the “fresh air” effect | nanoe / air-purifying module aged | Assess module; often non-critical |
As with any brand, the only fault that warrants a real repair-or-replace think is a failed compressor on an older machine.
Where some brands show a code on a screen, most Panasonic wall units signal a fault by blinking the timer light (and sometimes the power light) on the indoor unit in a repeating pattern — a certain number of flashes, a pause, then a repeat. It is the unit’s way of pointing at a category of fault. The honest, useful advice is the same as for any indicator: watch and count the blink pattern, note it, and tell your technician (or film it on your phone and send it to us). That pattern helps narrow the diagnosis before anyone opens the unit. What we will not do is publish guessed blink-to-fault meanings, because acting on a mis-read pattern wastes money — the reliable route is to record the pattern and have the fault confirmed on the unit itself. And a blinking light is never, on its own, proof that you need gas.
A Panasonic that runs warm is most often simply dirty — years of Malaysian humidity load the coil and blower with mould and dust until heat transfer collapses, and a proper chemical wash revives it. After that, the usual suspects are low refrigerant from a slow leak (find and repair it, never just top up a sealed system) and, on older units, a fading compressor or capacitor. Because “not cold” genuinely has several causes, the aircon not cooling guide works through them in order — essential reading before you agree to any “top-up” on a Panasonic.
A dripping Panasonic indoor unit points to a blocked drainage tray or pipe in nearly every case — the drain clogs with mould and dust, condensation backs up, and it spills into the room. Clearing and flushing the drainage during a chemical service normally solves it. Before assuming the worst, rule out the two impostors: condensation sweating off the copper refrigerant pipe, which can look like a leak, and a ceiling water stain that is actually a building leak unrelated to the aircon — the aircon leak vs pipe leak guide separates the two before any ceiling is opened.
A Panasonic that is completely dead or trips the switchboard on start-up has an electrical fault. On the many older Panasonic units still in service, an aged start capacitor is the classic, cheap cause of a motor that hums but will not turn. Treat as serious any unit that trips the breaker each time the compressor starts, or any burning smell — those signal an earth-leakage, wiring or compressor-start fault to be inspected, and you should stop resetting the breaker to force the unit on. If the circuit or the home’s wiring is the real weak point, our house rewiring guide and electrical services cover that side.
Panasonic markets air-purifying and efficiency features — nanoe and ECONAVI among them — and owners sometimes call because the “fresh air” feel has faded or a feature light behaves oddly. It is worth keeping perspective: these modules are comfort and efficiency extras, and a fault in one rarely stops the aircon cooling. Where a module has genuinely aged, we assess whether it is worth attention or simply non-critical, rather than treating it as an emergency. The core of the machine — compressor, fan, coil, board — is what determines whether your Panasonic cools and lasts, and that is where a sensible repair budget goes first.
Panasonic repair prices follow the failed part (market estimate 2026, indicative Klang Valley):
| Repair | Indicative price | Notes |
|---|---|---|
| Diagnostic visit | RM60 – RM120 | Often credited against the repair |
| Start capacitor | RM120 – RM280 | Common on older Panasonic units |
| Fan motor | RM250 – RM600 | Indoor blower or outdoor fan |
| Refrigerant leak find & repair | RM300 – RM800 | Find, fix, then re-gas — not a bare top-up |
| Control board (PCB) | RM300 – RM900 | Wide band; quoted after inspection |
| Compressor | Quoted after inspection | Repair-vs-replace territory on older units |
A bare gas “top-up” is often pitched at RM80–RM200; on a Panasonic as on any make, paying for gas without repairing the leak simply buys the same fault back.
For everyday parts — a capacitor, a fan motor — a good-quality compatible component is usually fine and saves money. For the control board and anything driving the compressor on an inverter model, a genuine Panasonic or properly matched part is the safer bet, because a poorly matched board can create fresh faults. The sensible rule is to fit the right part for the job, not the priciest one on every line, and we quote both openly so you can decide. On a much older non-inverter Panasonic, part availability itself sometimes tips the balance toward replacement — a point we raise honestly rather than after the fact.
Many Panasonic units in Malaysian homes are well past a decade old, which makes the repair-or-replace call a real one. A cheap, sound fix on a unit that otherwise cools well is worth doing. But once an old non-inverter Panasonic loses its compressor, or needs a string of parts, a modern inverter unit that uses markedly less electricity usually wins on total cost — especially for an aircon that runs long hours. Age, recent fault history, parts availability and your power bill decide it. We give the straight read at the quote instead of pushing a new unit by default.
The weak-cooling, dripping, smelly and noisy faults above are largely preventable. Routine filter washes plus a periodic chemical wash keep the coil, blower and drainage clear, easing the load on the compressor and board and heading off the common complaints before they start. Spotting a bearing noise or a slow drain early keeps a small job small. For what routine servicing should cost across brands, see the aircon servicing cost guide — a maintained Panasonic simply needs the repairman far less.
