Haier Air conditioning Error E2

What could the error code E2 mean that affects your Haier air conditioner?

Air conditioners have become essential allies in our homes and offices, especially during the hottest months of the year. However, like any other electronic device, these Haier air conditioners are subject to certain faults and errors that can negatively affect their operation.

The Error Code E2 in Haier brand air conditioners is a signal that alerts to a specific problem in the air conditioning system. This code is directly related to the resistors that are part of the device's PCB electronic board. When these resistors are in poor condition, the proper operation of the air conditioner may be compromised.

In order to find a solution to this problem, we first need to know the causes that originate it:

• Resistors on the PCB electronic board in poor condition: The resistors on the PCB electronic board can wear out or burn over time, causing Error Code E2 on your air conditioner.
• A failure in the PCB electronic board: The PCB electronic board is the one that controls everything in your air conditioner, if it is experiencing malfunctions, then rest assured that you have a problem that may be somewhat difficult to solve.
• Defective internal wiring connections in the air conditioner: There may be a defective connection between the resistors and the PCB electronic board, which generates Error Code E2. It is also likely that the internal wiring or connections are sulfated.

These are the causes that can cause an Error Code E2 in our Haier air conditioners. To find a solution, you will have to keep reading our article and stay with us, as we have prepared a list of solutions to fix this fault.

How can the error code E2 be fixed in the Haier air conditioner?

We're going to leave you here a list of solutions that we have prepared for you. Follow all these steps carefully and you will surely be able to resolve the E2 error code on your Haier air conditioner:

1. Turn off and disconnect the Haier air conditioner to rule out temporary errors in the system: An easy and simple solution to perform, this is the first thing we have to do when we have a problem with our air conditioner. To do this, you have to turn off the air conditioner completely and disconnect it from the power outlet for about 15 minutes. Then, turn your air conditioner back on to check if the E2 error code has disappeared. This procedure is very simple to do and will only take 15 minutes of your time. If the fault persists, continue with the following steps that we leave you below.
2. Perform preventive maintenance on the indoor and outdoor units of your air conditioner: If you haven't done maintenance on your air conditioner in the last 6 months, then it's time to do it. Regardless of whether this problem could or could not solve the E2 error code, you still need to maintain your air conditioner to prevent other error codes from appearing on the screen. Make sure to thoroughly remove any dirt from the filters of the indoor unit, as well as the radiators and coil connected to the compressor in the outdoor unit. If you feel it's necessary to replace the filters, don't hesitate to do so. Also, check the water outlet, make sure it's not blocked as this can cause water to be discharged through the indoor unit.
3. Check the internal wiring of the air conditioner and connections that may be sulfated: If you are doing maintenance on the air conditioner, take the opportunity to check that all wiring is in good condition. Also, check the condition of all connections, make sure there are no sulfated connections. If you find sulfate on the connections, then use a specific product to remove it or an electronic cleaner and a brush to clean everything well. Once you see everything in perfect order, reconnect all the wiring, assemble your air conditioner, and check if the E2 error code has disappeared.
4. Inspect the PCB electronic board with a multimeter and perform preventive maintenance: Inspect the PCB electronic board of your air conditioner visually to check if you notice any signs of sulfate, disconnection, any burnt or scorched component, etc. It is likely that one of the lines that connect the resistors has broken or burned, and you will need to thoroughly check this electronic board. Use a multimeter and check the continuity of each of these resistors, make sure they have the correct ohm reading according to the manual and the manufacturer's specifications. If you notice that the board has problems with any component or resistor, then replace it with a new one that is the same model, resistance, impedance, ohms, etc. It is important that the replacement is exactly the same model, value, and specific parameters as the one that has failed, otherwise we cannot guarantee the proper functioning of the air conditioner and/or that another error code may appear.
5. If the problem persists, you will have to review everything we have mentioned above and follow the steps to the letter: You have to review all the steps we have mentioned again to rule out any possible cause that may have generated this problem in the air conditioner. If you cannot identify the cause of the problem, then the PCB electronic board of your air conditioner is likely damaged and you will have to replace it with a new one, of the same model and compatible with your air conditioner. If you think this task has become somewhat difficult to solve, then we recommend that you leave the matter in the hands of Haier's technical personnel, the refrigeration experts.
6. Call Haier's technical support and request a home visit: Arrange a home visit with a qualified refrigeration professional, or better yet, with Haier's technical support itself. That's if you haven't been able to solve anything on your own and the E2 error code continues to appear on the screen of your air conditioner.
