Haier Air Conditioner Error Code E7
If your Haier air conditioner starts displaying the error code E7, it means that there is a problem with the unit’s evaporator temperature sensor.

Haier Ac Error Code F
If your Haier air conditioner starts displaying the error code “F,” it means that there is a problem with the unit’s outdoor fan. This can be caused by a number of things, including a build-up of dirt and debris around the fan or a problem with the fan motor itself. Regardless of the cause, you’ll need to clean or repair the outdoor fan before your Haier AC will work properly again.
Cleaning the Outdoor Fan The first thing to try if your Haier AC is displaying an error code “F” is to simply clean the outdoor fan. You can do this by using a soft brush or cloth to remove any dirt and debris that has built up on the blades.
If there doesn’t seem to be any visible build-up, you can also try spraying the blades with a garden hose to remove any invisible grime. Once you’ve cleaned off the blades, turn on your Haier AC and see if the error code goes away. If it does, great!
If not, then you’ll need to move on to troubleshooting other potential issues. Checking for Other Issues There are a few other potential causes of an error code “F” on your Haier AC unit.
One possibility is that there is something blocking the path of air flow from the outdoor unit back into your home – such as leaves or branches.
Another possibility is that there could be an issue with one of the wires leading to or from the outdoor fan motor itself. To check for these issues, start by visually inspecting both units (outdoor and indoor) for any obvious blockages in air flow or signs of damage/disconnections in wiring.
If everything looks clear and intact, then you can use a multimeter to test continuity in each wire leading from/to the outdoor unit’s fan motor – just follow these simple steps:
1) Turn off power to both units at your breaker box
2) Remove outer coverings from both units so you have access to all exposed wires
