A：TEAs require a stable power supply to work correctly. Insufficient power supply may result in the TEA not functioning properly, leading to temperature control failure. To avoid this issue, ensure that the TEA has sufficient power and follow the power requirements provided by Huajing.

A：The TEA generates a hotspot due to its working principle, which needs to be addressed in a timely manner. If not dealt with, it may affect the temperature control effect of the device. To avoid this issue, follow the guidelines provided by Huajing during installation to ensure the hotspot is sufficiently dissipated.

A：The TEA circuit can be damaged during installation if the correct installation steps are not followed. These damages may affect the performance of the TEA and may even cause damage to the device. To avoid this issue, follow the installation guide provided by Huajing.

A：Poor contact can be a common issue when installing a TEA. TEAs are usually connected to the target device through a thermal conductive plate. If the contact is poor, it may affect the heat dissipation and performance of the device. To avoid this issue, ensure that there is good contact between the thermal conductive plate and the device and appropriate pressure is applied.
