Oil/gas Burner Cause Of Issue Jul 18, 2017

Oil/gas Burner cause of issue

Gas burner may appear the phenomenon of failure and fault reasons to determine

The burner is in operation regardless of which of the following "possible causes", the burner is immediately locked and shut down, effectively ensuring that the burner is operating safely.

Symptom (1): Power on, burner does not start, the control box does not light up the fault signal.

Possible Causes :

 (A) may be a small problem, such as power is not connected. It is also possible that the gas switch valve has not been opened or the gas pressure is insufficient (below the setpoint on the low pressure switch).

  (B) Please check the fuse of the power supply. Please also check if the temperature adjusted on the thermostat is appropriate. If the burner is connected to other automatic control devices, check if there is no power supply to the burner due to the influence of these devices.

 (C) Check that the voltage is normal. The burner's control box basically has a low voltage protection function, when the voltage is too low, the burner can not start.

 (D) Please check whether the control box of the burner is firmly inserted into the socket. Please also check whether the power supply wiring is loose.

 (E) may be a control box failure (damage).

Symptom (2): Turn on the power, the burner can not start, the control box lights up the fault signal, or will light up the fault signal later.

Possible Causes :

 (A) may be a control box failure (damage).

 (B) may be a malfunction of the burner motor. The motor can not start in addition to the motor coil or capacitor may be damaged, there may be a bearing problem, perhaps the impeller can not be locked.

Symptom (3): burner normal start, but in the "hair dryer" during the interruption of operation, the control box lights up the fault signal.

Possible Causes :

(A) may be a control box failure (damage).

(B) the wind pressure switch is not action, the wind pressure switch is damaged, when the wind pressure reaches the set value contact can not move the wind pressure port or the pressure tube is blocked, check the wind pressure switch set value, is set correctly, the fan Failure caused wind pressure is too low.

Symptom (4): burner normal start and "ignition" after the burner control box lights up the fault signal.

Possible reasons: burner can not spray the flame, can be divided into the following three cases:

(A) No ignition of the arc.

(B) The solenoid valve can not output gas.

(C) The output gas can not be ignited due to improper adjustment or abnormal ignition arc.

Symptom (4A): No ignition of the arc.
