Haier air conditioner troubleshooting. You rely on your Haier AC to cool down your room. This is one of your most crucial appliances because you use it all year round and even during the hot season, humid days.
When your air conditioner isn’t working correctly, you’re always left wondering what to do and whether or not it’s more economical for you in the long run to contact a professional or if there is something else that can be done in order to remedy the situation.
Even if you aren’t an HVAC pro, there are a few things here that may help you figure out what’s wrong with it.
For example, start by looking at some of the most common issues people tend to run into before calling a service center like having loose power cords or being unable to find a leak source in case of internal condensation.
Haier air conditioner troubleshooting
How to troubleshoot a Haier air conditioner. You should begin by troubleshooting the most common issues with your Haier window air conditioner before calling a specialist or a professional.
Haier air conditioner won’t cool
If you have a clogged air filter, your hands are going to freeze every time you try to turn on the cooling system, because the AC can’t work properly. It’s just a waste of money.
Clogged filters mean that the fan is moving air but it’s not getting all of the way through the unit and into your living room or bedroom. All the heat and moisture that your heaters trying to get rid of is still hanging around and so humidity will keep increasing.
You want to avoid this clogging at all costs. The only thing you need to replace something is if there is visible damage or malfunctions
It’s rare also for this problem to be caused by a fault in the compressor, so you may wish to attempt any remedial action before deciding whether to replace the entire unit.
A/C compressor does not work
The compressor most likely is not the problem. It is important to check the overload protector, capacitor, and even the compressor before replacing the compressor. Oftentimes, one will find that these three components have gone bad and need to be replaced due to a blown fuse or faulty wiring.
Often, control boards are misdiagnosed. If the temperature control board is defective, check more commonly defective parts such as the compressor overload, and the capacitor. You should replace the temperature control board if all of the other components are working properly.
A/C fan not working
Try moving the blade with your hand. If it’s not moving freely, this means that the motor is defective and needs to be replaced. You’ll need to check for other potential problems first like loose wires or insulation resistance, but ultimately you’ll probably want to replace the entire motor unit as a whole.
Relay boards are also often misdiagnosed; before replacing the board, make sure you check more common problems like corroded wiring and loose connectors. Otherwise, when replacing parts, check your fan’s motor capacitor and even its bearings which may have worn out over time.
The air conditioner will not turn off
The thermostat is an electronic device that sits on your air conditioner. It receives signals from the control board on how hot or cold the air should be, and adjusts accordingly to power a switch that will change electrical current to the heater and fan motor.
It may also call for a secondary function such as deicing if there are any issues with snow buildup. If your thermostat’s internal circuitry becomes faulty, it might not send the proper signals to switch your AC/Heater on and off as necessary.
You need to be sure that all of the parts in your AC that ensure optimal comfort during winters like good windshield wiper blades are intact before testing out defective circuits inside of your AC unit.
If you are confident that everything else is working properly aside from the circuits in it, test out these three basic parts: Control Board, Wireless Receiver, and Remote Transmitter.
Air conditioner remote control Problems
First, try replacing the batteries in your remote control. If installing fresh batteries doesn’t solve the problem and you can still operate the air conditioner manually, your remote control might be defective.
If you think your remote is defective, replace it. If you suspect there’s a fault or malfunction with your main control board, replace it first before getting a new replacement remote control unit.
Loud or noisy air conditioner
Dual shaft fan motor bearings can be permanently lubricated, but over time the old oil breaks down, causing the motor to become noisy. If your fan is squeaking, it’s a good indication that you need to replace your dual shafted motors.
Besides being noisier than before, these motors may also be inefficient. Other signs that your drives are in need of replacement are visible burn spots on the windings or acromegaly and stiffness when rotating from one position to another.
Furthermore, it is an indication that the rotor may have developed spots that are rubbing against the fan housing.
