Causes and Remedies For Fujitsu Mini Split Error Codes
If your Fujitsu mini split is giving you an error code, don’t panic. You can quickly and easily fix the issue by rebooting the device. You can also flip a circuit breaker or reset the main electrical panel. However, if you’re not sure what’s wrong, you may need to have a technician examine the device in detail. Listed below are some common causes and remedies for Fujitsu mini split error codes.
In the event the mini-split isn’t working properly, it may be caused by a wiring issue. If so, the outdoor unit’s wiring needs to be inspected. On Fujitsu models, there are three terminals for electrical wires. Connect hot wires to L1 and L2, while the ground wire should be attached to C. The ground wire is green and bare. Before checking the wiring, make sure the power to the mini-split is turned off. To do so, turn the main electrical panel’s circuit breaker to off.
Another common cause of mini-split error codes is improper drainage. While the system is running, it draws water from the air and collects it in a reservoir inside the head unit. This water eventually drains out through a pipe outside the home. However, there are instances where there is no drainage, and water will drain into the home. When this happens, a mini-split error code like E-09 may indicate a potential water damage problem. If you continue to run the mini-split when the error code appears, you may end up with a water-logged home.
The most common cause of mini-split error codes is the connection between the outdoor unit and indoor unit. When a wire is damaged, or the connections are severed, the two units cannot communicate. As a result, the indoor unit will no longer receive the commands, and the mini-split will go into error mode. Hopefully, the problem will not be as frustrating as it sounds, but you can solve it on your own.
Other common causes of Fujitsu mini split error codes include the use of coloured sensors to monitor the temperature of the indoor air. In addition, the unit may be flashing an LED or displaying an error code. To solve this problem, you need to make sure that the indoor air sensor is properly set. If this fails, you need to check if the pipework temperature is in the range of 0-10C or the remote control is faulty.
