The burner may encounter such problems during use. The damper stops under control. It is possible that the damper position switch signal does not feed back to the program signal. At this time, you should check whether the damper wiring is loose or the switch is out of order. Summarize the problem Reasons and solutions, there are several situations below!
1. General failure: The burner motor does not turn?
Causes: a. no voltage; b. fuse damage; c. motor failure; d. control circuit interruption; e. gas transmission interruption; f. control failure;
Solution: a. Connect the circuit; b. Replace; c. Repair; d. Find the disconnection point, contact or disconnect the regulator or monitor; e. Open the ball valve, and notify Gas management organization; f. Manual reset inspection; g. Replace thermal relay.
2. Insufficient air volume:
1. The burner motor runs, but stops after pre-purging, the burner motor runs, but stops after about 20 seconds (only for equipment with a sealing inspection device)?
Causes: a. The air pressure switch is out of order; b. The pressure switch is contaminated and the pipeline is blocked; c. The solenoid valve is not sealed;
Solution: a. Replace; b. Clean; c. Eliminate leaks.
2. Burner motor runs, but shuts down in pre-purge state after 10 seconds?
Causes: a. The contact of the pressure switch is not connected to the operating position (the air pressure is too small); b. The blower is contaminated and the heat relay operates; c. The direction of rotation of the burner motor is wrong;
Solution: a. Correctly adjust the pressure switch, and replace it if necessary; b. Clean; c. Change the pole of the power supply.
3. Ignition failure: The burner motor is running, the voltage is applied to the terminal 16 of the controller, there is no ignition, and the machine will stop after a fault?
Causes: a. The ignition electrode distance is too large; b. Contaminated; c. The ignition electrode or circuit is grounded; d. The ignition transformer is out of order;
Solution: a. Adjust the electrode spacing; b. Clean; c. Exclude the grounding, replace the damaged electrode or cable; d. Replace the ignition transformer.
4. The flame is not formed:
1. The motor is running and the ignition is normal, but it stops after a fault?
Reasons: a. The solenoid valve does not open because the solenoid valve coil is damaged or the cable is broken;
Solution: a. Replace the solenoid valve or eliminate the failure of the circuit, and check the voltage on the terminal 17.
2. In the equipment with the sealing test device, the sealing is not strict; the burner motor is running, the ignition is normal, but it stops later (no fault display)?
Causes: a. The solenoid valve is not sealed; b. Insufficient air supply; c. The filter is blocked;
Solution: a. Eliminate leaks; b. Clean or replace.
