(1): After the power is turned on, the burner does not start and the fault light on the control box does not light up.
Possible causes:
(a) It may be just a small problem, such as the power is not connected. It may also be that the gas switch ball valve has not been opened or the gas pressure is insufficient (lower than the set value on the gas low-pressure switch).
(b) Please check the fuse of the power supply and whether the temperature adjusted on the thermostat is appropriate. If the burner is connected to other automatic control devices at the same time, please check whether the power supply to the burner is not affected by these devices.
(c) Please check whether the voltage is normal. The control box of the burner basically has a low voltage protection function. When the voltage is too low, the burner cannot start.
(d) Please check whether the control box of the burner is firmly plugged into the socket and whether the power wiring is loose or not.
(e) It may be a control box failure (damage).
Fault phenomenon (2): After the power is turned on, the burner cannot start, and the control box lights up the fault light, or lights up the fault light later.
Possible causes:
(a) The control box may be faulty (damaged).
(b) The burner motor may be faulty. In addition to the possibility that the motor coil or capacitor is damaged, the motor cannot start because of a bearing problem, or the fan impeller may be stuck and cannot rotate.
Fault phenomenon (3): The burner starts normally, but the operation is interrupted during the "blowing program", and the control box lights up the fault light.
Possible causes:
(a) The control box may be faulty (damaged).
(b) The air pressure switch does not work, the air pressure switch is damaged, and the contacts cannot work when the air pressure reaches the set value. The air pressure port or the pressure measuring tube is blocked. Check whether the set value of the air pressure switch is set correctly. The fan failure causes the air pressure to be too low
