Is your Haier air conditioner control panel not working, and you cannot operate the AC? Well, most of the issues are things you can troubleshoot, and this guide will enable you to do so.
Mostly, the control panel of a Haier air conditioner doesn’t work because the AC lacks power, the control panel is locked, or the remote control is non-responsive. It could also be due to a faulty thermostat, fan, evaporator coil, or control module.
Remember, your Haier AC won’t do anything if the control panel is not responsive. That means you should act fast to fix it, and it starts with identifying the fault.
We’ll break the guide into separate steps to enable you to identify the fault and fix it quickly. In that case, you wouldn’t have to go through all the steps unless necessary.
And once you exhaust all the steps and can still not fix the control panel, you can opt to contact Haier or an expert AC technician.
But overall, it’s important to start troubleshooting with a reset. Sometimes all your air conditioner control panel needs to start working is a reset, which explains why it’s the first step in this guide.
Let’s jump into the guide!
In a hurry? Below are the issues to consider once the reset fails to get your Haier air conditioner control panel back working.

Troubleshooting Guide for A Haier Air Conditioner Control Panel Not Working
Consider the eight steps below to troubleshoot your non-working Haier air conditioner control panel.
Step 1 (Reset the AC)
Before you can work on any repairs or inspections, reset your air conditioner when the control panel appears not working. There is always the chance that the reason is a software glitch, something you can fix with a reset.
Overall, there are two easy ways to rest on a Haier air conditioner.
Option 1 – Use the power cable
If you follow the air conditioner’s power cable, you’ll find the reset/test button near the electric outlet. That button allows you to reset the air conditioner seamlessly, and you only need to push it down if it’s up.
After that, you can turn on your Haier AC to see if the control panel is working.
Option 2 – Use the remote
While it’s possible to reset a Haier AC without a remote, the remote offers you the most hassle-free option. You should locate the tiny reset button on the remote (at the bottom right end) and press it with an unfolded paper chip. Then wait for the air con to reset before having it on.
Note that once you are successful with the reset and your control panel starts working, you don’t have to do anything else. But if it doesn’t work, then you can proceed with the steps shared next.
Step 2 (Ensure the air conditioner has power)
The Haier ac control panel won’t work without power. So, it’s imperative that you confirm if you’ve power. While you cannot do anything in case of a power loss, consider the following in its absence.
- Could the power cord be unplugged? – Check the power cord to ensure it is correctly plugged into the socket. The AC won’t start if it’s loose.
- Could the air conditioner be off? – Don’t forget to check if the AC is turned on. It could be off without realizing it.
- Could the power breaker be off? – Inspect the circuit breaker to ensure it’s not tripped. If it is, reset it.
- Could the reset button be tripped? – Also, inspect the reset button on the power plug to ensure it’s not tripped. You may need to unplug the AC and press it to reset it.
- Could the power outlet be faulty? – Don’t forget to check the power socket for faults if your AC won’t power on up to this point. Try plugging in another working appliance to see if it works. If it doesn’t, replace the socket or find an expert to help you.
Step 3 (Unlock the control panel)
If your Haier air conditioner has power, but the control panel still will not work, it could be locked. A locked control panel is inoperable, not until you unlock it.
You can know if the control panel is locked if the lock signal is on. Once that’s the case, use a ballpoint pen to press the remotes’ ‘lock’ button twice to unlock the unit.
Step 4 (Check the remote to see if it’s working)
If you are using the remote control to operate the control panel and nothing is happening, it could be because the remote is unresponsive.
Check the batteries to see if they are correctly installed. If they are okay, you can try replacing them. Or try to operate the control panel without the remote. That’ll tell you if the remote is faulty or not. If it is, you’ll need to replace it.
Step 5 (Inspect the thermostat for fault)
There is a relationship between the thermostat and the control panel. If the thermostat malfunctions, you will likely press the control panel many times. That improves the likelihood of wearing down the control panel.
In the end, it’s not just the thermostat that becomes faulty (unable to control the AC’s temperature) but also the control panel.
If so, you may need to replace both components. But since this can be a bit technical, allowing an AC repairer to handle it may be wise.
Step 6 (Inspect the fan for fault)
Though less likely, a broken fan can be why the control panel is not working. Once the fan breaks or becomes faulty, it cannot blow any air above the condenser coils. That forces the air conditioner to turn on when it’s necessary.
So, the control panel may appear to malfunction when the problem is not the control panel but the fan. In such a case, you should replace the fan, not the control panel.
Step 7 (Check the evaporator coil for fault)
Sometimes the problem has nothing to do with the control panel but with the evaporator coil. If the evaporator coil is clogged, burnt, or worn out, air won’t come out of the vents when you press the control panel’s buttons.
So, if that’s the case, inspect the evaporator coil to identify the fault. Start by examining it for clogging and clean it if that’s the case.
But if the evaporator coil is burnt or worn out, replace it. An expert AC technician can help you do that.
Step 8 (Replace the control module)
Once you get to this point and your control panel is not working, it’s best that you replace the control module. But before you do, you’ve to be sure that the Haier air conditioner control board is bad.
Its contact plugs could be clogged and need some cleaning with a contact spray cleaner. If that’s not the case, then you should go ahead with the module replacement.
Haier Portable Air Conditioner Control Panel Not Working
If your portable Haier AC control panel is not working, perform the following troubleshooting:
- Reset the air conditioner either by pressing the reset button on the remote or pressing the reset switch on the power plug
- If the reset does not work, ensure your portable AC has power. That means appropriately plugging it, resetting the reset switch or breaker, and fixing a faulty outlet
- Check the control lock indicator to see if it’s on and disable it
- Ensure the remote control is working
- Inspect the thermostat, fan, evaporator coil, and control module for a fault in the same order and replace what’s faulty
Haier Window Air Conditioner Control Panel Not Working
The troubleshooting of a Haier window AC control panel is similar to that of a portable AC. It all starts with the reset. If the control panel works after that, you don’t have to do anything.
However, if the reset won’t work, perform these checks:
- Ensure your window AC is powered on and fix any power issues present
- Unlock the control panel if the control lock function is on
- Check the remote to ensure it’s working correctly. If it is not, replace it
- Replace the thermostat fan, evaporator coil, or control module, depending on what’s faulty
