L2 fault of Shenling air conditioner

The L2 failure of Shenling air conditioner may cause the air conditioner to fail to work normally, resulting in circuit failure or mechanical problems, which may lead to abnormal cooling or heating. Therefore, we need to troubleshoot through the following aspects:

1. Check whether the power cord is firmly connected: if the connection is not tight or the contact is poor, the air conditioner will not start or stop after starting.

2. Check whether the external circulation coil of the air conditioner is too dirty: too dirty will hinder the air circulation, lead to the decrease of cooling or heating effect, and may also lead to frost inside, affecting the normal operation of the air conditioner.

3. Check whether the internal mechanical structure of the air conditioner is out of order: check whether the main control board and circuit board are damaged, and replace the nameplate or capacitor in time if it is found to burst.

4. Check whether the filter element of air conditioner is too dirty: too dirty filter element will affect the normal use of air conditioner and need to be wiped or replaced.

If the L2 fault can't be solved after the above-mentioned troubleshooting, it needs to be checked and handled by professional air-conditioning maintenance personnel. During maintenance, it is recommended to wear tools and maintenance gloves. Avoid potential safety hazards.
