How to fix the F1 error in Haier AC? You can fix the F1 error by resetting your Haier air conditioner. There is a power button present on Haier remote control. F1 error means that your temperature sensor is not working.
What is an F1 Error?
The code F1 has turned off the temperature sensor of the indoor unit’s heat exchanger. This sensor is in charge of monitoring the temperature of the evaporator in the refrigerator. The compressor is turned off if the temperature dips below zero to avoid the evaporator from becoming iced up.
To resolve the issue, you must first determine whether or not the sensor is working. Switch to a new one as soon as possible if it fails. If you see this problem frequently, you might consider purchasing a household gadget to stabilize the voltage or building your voltage stabilizer.
It will help equalize the voltage throughout the network and keep the equipment from overheating. According to Ideal, low water pressure is the official definition of the F1 fault code. In most cases, low pressure inside the central heating system is the cause of this problem, as the term suggests.
Causes of F1 Error Code
Faulty Wiring
Wiring connections are not secure.
IPM Error Message
Error with the system pressure
PCB on the mainboard is faulty.
The outside unit is not properly ventilated.
Motor for an outdoor fan
Summary
The F1 error number is shown when there is insufficient water pressure in your Ideal boiler, resulting in the boiler locking out and ceasing normal functioning.
How to Fix the F1 Error in Haier AC?
The error code ‘F1’ indicates that the indoor and outdoor units’ PCBs cannot interact with one another. You can do the following tests to determine the source of the problem:
Check that all of the connections are clean and secure. Corrosion on connections can cause this error; clean each with a mild abrasive paper to eliminate the problem.
Check that all of the connections are in the right locations and that wiring schematics are printed both inside the indoor unit and on the PCB casing of the outdoor unit.
Make sure there are no gaps in the black communication cable. Ensure the connections are correctly linked and that the isolator is turned on before proceeding forward.
If you have checked everything and found that all of the connections are clean, tight, and proper, there is likely an issue with the PCB. Follow these simple procedures to resolve the F1 issue in your Haier air conditioner:
Turn off the AC by pressing the power button.
For 2-5 minutes, turn off the power at the breaker panel. Resetting the unit is a simple process.
Try to turn on AC and see whether the issue is resolved.

Causes of F1 Air Conditioner Failure
Neglecting annual maintenance
The performance of your air conditioner is dependent on the frequency with which it is serviced. The services of a professional technician can detect any problems before they manifest themselves.
Your air conditioning coils should be cleaned thoroughly, and your system should be examined as part of your regular maintenance. Failure to maintain your system may also result in your manufacturer’s warranty voiding.
Frozen coil
Airflow issues in your system can be caused by dirty air filters, which result in an F1 error in Haier AC. Cleaning or changing your air filter regularly and keeping your ductwork clean are two important tips to follow to avoid a frozen coil.
Leak in the refrigerant
Any leak should be fixed and refilled by a professional technician since the refrigerant damages the environment. If your system’s refrigerant is not at the right level, your air conditioner may cause an F1 error.
Damaged compressor
When a compressor fails in an air conditioner, it is due to an underlying issue that is putting stress on the system. These issues include filthy coils, low refrigerant, electrical difficulties, etc. Annual maintenance may typically detect worn or broken parts before they become a cause of an F1 error fr your Haier AC.
Faulty circuit breaker
If your air conditioner fails, one of the first things you should check is your circuit breaker or fuse for damage. Remove the fuse or reset the breaker after waiting 15 minutes to allow your air conditioner to cool down completely before replacing it.
Faulty thermostat
If your thermostat is not functioning properly, your air conditioner may cycle on and off incessantly or fail to operate. That being the case, it may be time to look for a replacement thermostat.
Summary
If nothing of these methods solves the F1 error in your Haier AC, you may have triggered a high-pressure limit switch. In such a scenario, we recommend that you contact a qualified expert.
Most Common Error Code of Haier AC
| Error Code | Meaning/Reason | Possible Solutions |
|---|---|---|
| E1 | Faulty sensor for tube temperature/coil pipe. | Analyze any sensors or circuits connected to a tube or coil pipe temperature. |
| E2 | Sensor failure at room temperature. | Check the temperature sensor and any associated circuits in the room. |
| E4 | Protection against freezing is a problem. | Once the anti-freeze protection has worn off, you may reclaim your features. |
| FL | The water chassis is filled. | Drain the water from the appliance and turn it back on. |
