Maintenance
1. Check the power supply:
Make sure that the heater is inserted into a normal socket, and the power cord is not damaged.
2. Check the circuit:
Open the heater shell and check whether there is damage or aging of circuit elements such as capacitors, relays, switches, circuit boards.
If it is damaged, replace the corresponding component or the entire circuit board.
3. Check the temperature control element:
If the temperature control element is found to be damaged, it needs to be replaced.
4. Cleaning filter:
Regularly clean the filter to keep the air circulation smooth and improve the heating effect.
5. Clean the air duct and drain pipe:
If the air duct or drainage pipe is found to be blocked and clean up.
6. Check and replace fuse:
If the fuse is broken, it needs to be replaced.
7. Check the fan:
If the fan faults cause a large noise or a small air volume, the fan needs to be checked and replaced.
8. Check and reinstall the drain pipe:
If the heaters leak water, check whether the drainage pipe is blocked or installed properly, and is cleaned or reinstalled.
9. Pay attention to safety issues:
When repairing the heater, first disconnect the power, and wait until the heater completely stops working before repair.
