Haier Air Conditioner Symbols and What They Mean

Haier air conditioner symbols cover modes, fan speeds, timers and the lamps on the indoor unit. Haier remotes carry a symbol most brands do not have. Press HEALTH and a lamp inside the unit switches on, aimed at the air coming in. It is doing something real, and almost nobody who owns one knows it is there.

This page sets out every Haier air conditioner symbol in plain language, taken from Haier owner manuals rather than from guesswork, and it covers air conditioners only rather than the ovens and fridges that dominate a search for Haier symbols.

Haier air conditioner symbols at a glance

If your system is a different brand, our general guide to air conditioner symbols covers the ones every manufacturer shares.

The HEALTH symbol, and what it actually does

This is the Haier feature worth knowing about, because it is genuinely different from the ioniser most brands fit.

Haier calls the technology UVC Pro, and describes it as using UVC band rays at the air inlet, where direct exposure to those rays destroys the DNA and RNA structure of bacteria and viruses. There is a physical UV lamp inside the unit with its own part number, which means it is a component that can eventually need replacing rather than a software setting.

Press the HEALTH button and the remote displays the health symbol, and on the unit the UV lamp comes on, which Haier says may show as a tinged blue light near the air inlet. On some models an extra function button cycles through sleeping, health, healthy airflow position 1, healthy airflow position 2, power and air sending.

So a tinged blue light near the air inlet of a Haier is not a warning. It is the UV lamp doing its job.

Self clean, and the smell it prevents

Haier fits a self clean function and describes it plainly. Press the button and CL appears on both the indoor unit panel and the remote. The cycle runs for 20 to 30 minutes and exits automatically, signalled by two beeps.

That cycle dries the inside of the indoor unit out. Damp coil, dark box, warm room is where the musty smell comes from, and using self clean regularly is the built in answer to it.

One thing to expect in cold weather. Haier states that if the outside ambient temperature drops below zero, the error code F25 may occur during self cleaning operation, and that this is a normal protective measure. F25 during a winter self clean is not a fault.

I FEEL, and where to leave the remote

Haier describes I FEEL as optimising the working conditions of the air conditioner to deliver airflow at the best temperature for your comfort. In practice the remote measures the temperature where it is sitting and sends that reading to the indoor unit every three minutes.

Haier adds an instruction most brands leave out. Position the remote controller within the acceptable range of the air conditioner. If the remote is out of range the unit stops receiving updates, and it will be working from an old number.

The usual catch applies as well. A remote left in a sunny window tells the unit the room is hotter than it is.

What does the padlock mean on a Haier remote?

The LOCK button locks the buttons and the LCD display, and a lock symbol appears while it is active.

On a Haier wall split the combination to set and cancel it is HEALTH and HEALTH AIRFLOW pressed at the same time. Several Haier manuals list a LOCK button without giving a combination, so if yours has a dedicated button, that button is the answer.

On a ducted system with the wired controller it is different again. Press the relevant key and MENU together for five seconds to set or cancel the child lock, after which no keys work at all.

Temperature range, and an honest gap

Haier publishes a temperature range for its ducted systems through the wired controller. Dry mode runs between 16 and 30 degrees, low temperature dehumidification between 10 and 30, and the energy saving mode limits cooling and dry at the low end and heating at the high end.

For Haier wall splits, no settable range is published in any of the Australian manuals available. Five separate hi wall manuals document one degree increments and ambient operating ranges without ever stating a minimum and maximum you can set.

So this page does not give you a number for a wall split. Plenty of sites will. None of them can point at a Haier document saying it.

There is no filter light on a Haier wall split

Worth stating plainly. No Haier wall split manual documents a filter reminder indicator or a reset for one. Haier gives a schedule instead, and it is a short one. Normally the filter should be cleaned every 15 days.

On a ducted system with the wired controller a filter cleaning icon does exist. When it displays, switch to it and press MENU again to cancel the display once you have cleaned the filters.

Haier error codes

These are the indoor unit codes Haier Australia publishes.

E7 is the one people search for most. It means the two halves of your system have stopped talking to each other. The indoor fan often still runs while nothing useful happens to the temperature, which is exactly what a communication fault feels like in the room. The cause sits in the wiring between the units, in a board at either end, or in the power supply to the outdoor unit, and none of those is a homeowner job.

Outdoor faults use F codes, which Haier pairs with a flash count on the outdoor board. They cover the compressor, the inverter module, voltage problems, the four way valve, and every temperature sensor on the outdoor side. Those are technician territory.

Codes E0, E3, E5, E6, E8 and E9 do not appear in Haier Australia documentation. If your unit shows one of those, the meaning is not something Haier has published here.

The flashing white light question

This comes up often enough to deserve a straight answer.

Haier’s Australian manuals do not publish indicator lamp colours at all, white or otherwise. The only light they describe is the health UV lamp, which can show as a tinged blue light near the air inlet.

What Haier does document is that the operation lamp flashes when an error is detected, and that the wifi indicator flashes while pairing. A light you are reading as white is most likely one of those, or the health UV lamp, which can read as a pale light in a bright room.

So rather than looking up a meaning that does not exist, check which lamp is flashing and whether the unit has stopped. A flashing operation lamp with the unit stopped means a code is waiting to be read.

Running a Haier without the remote

There is an emergency switch on the indoor unit for when the remote is defective or lost. Haier describes it as letting the air conditioner operate automatically for a limited period. Press it and one beep confirms the start.

The preset temperature differs by model. One Haier range runs at 24 degrees with auto fan speed in cooling or heating depending on the room. Another cools at 26 degrees and heats at 23.

There is also a test operation switch on some models. Holding it for more than five seconds, until two beeps, starts a cooling operation. That is a service function rather than something to use day to day.

How to reset a Haier remote

Haier documents a reset button pressed with a sharp pointed article when the remote appears abnormal.

1. Turn off the unit.
2. Press the reset button on the remote with something pointed.
3. The screen displays several icons, then returns to blank with the time flashing at twelve.
4. Set the clock again.

On powering down the unit itself, Haier gives an instruction most people get backwards. In order to protect the unit, turn the air conditioner off first, and at least 30 seconds later cut off the power. Killing the power at the wall while the unit is running is the thing to avoid.

Haier behaviour that looks like a fault and is not

• It will not restart straight away. When the unit is stopped it will not restart for three minutes, to protect the system.
• No warm air at the start of heating. Warm air blows out after a short period due to the cold draft prevention function.
• The fan runs oddly in dry mode. Haier states that when the room temperature falls below the setting plus two degrees, the unit runs intermittently at low speed regardless of the fan setting.
• Mist coming out of the indoor unit. During cooling or dry this is the sudden cooling of indoor air.
• Swishing or gurgling. Refrigerant flowing in the system.
• A cracking noise. The casing expanding or shrinking with temperature changes.
• An odour on start up. Haier says the system circulates smells from the interior air, such as furniture, paint or cigarettes.
• F25 during a winter self clean. Covered above. Normal below zero outside.

Which Haier symbols point at a real fault?

• E7, the communication fault between indoor and outdoor units.
• E14, an indoor fan motor malfunction.
• Any F code on the outdoor side.
• A flashing operation lamp with the unit stopped, outside of a self clean cycle.
• Water appearing on the wall below the indoor unit.
• F25 in warm weather, outside a self clean cycle, where the normal explanation does not apply.

Getting your Haier back to doing its job

Most symbols on a Haier are the unit telling you what it has been asked to do. A tinged blue glow near the air inlet is the UV function. CL is a cleaning cycle. A padlock somebody set by accident is far more common than a broken remote.

Read the chart at the top, match what is on your screen, and give the unit three minutes before deciding anything. Worth knowing too is how often you should service your air conditioner, because a Haier wall split will never remind you about the filter and Haier itself asks for every 15 days.

When the display shows E7 or an F code, that is the point where guessing costs more than asking. We send a licensed technician who works on split, multi head and ducted systems across Melbourne, and the price is confirmed before any work starts.

If every symbol reads correctly and the air is still not cold, our guide on why an air conditioner is not blowing cool air takes it from there.

For anything the remote will not explain, our air conditioner service in Melbourne covers Haier split and multi head systems, and a quote takes a couple of minutes to request.
