The red light on a boiler burner is usually a fault indicator, indicating that there is some kind of problem with the burner.
Here are some common reasons and solutions that may cause the red light to light up:
1. Failed to ignite
Cause: The burner failed to ignite successfully, which may be due to a faulty igniter, insufficient fuel supply, or a gas supply problem.
Solution: Check whether the igniter is working properly and ensure that there is sufficient fuel or gas supply.
2. Fuel or gas problems
Cause: Clogged fuel pipes, poor fuel quality, insufficient gas pressure, etc.
Solution: Check whether there is enough fuel in the fuel tank, clean the fuel pipes, and ensure that the fuel quality meets the requirements.
3. Insufficient air supply
Cause: Insufficient air flow will cause incomplete combustion and trigger the safety device.
Solution: Check whether the air intake is blocked and ensure that the air supply is normal.
4. Failure of the thermostat or safety device
Cause: Thermostat failure or safety device is triggered (such as overheat protection, pressure switch, etc.).
Solution: Check the thermostat and safety device to ensure that they are working properly.
5. Electrical failure
Cause: Power supply problem, loose wiring or control system failure.
Solution: Check the power supply and circuit connection to ensure that all wiring is good.
6. Burner blockage
Cause: The burner nozzle or filter is blocked by dirt, affecting combustion.
Solution: Clean the burner and filter regularly to ensure that they are unobstructed.
7. Smoke exhaust system problem
Cause: The flue is blocked or the smoke exhaust fan is faulty, resulting in poor smoke exhaust.
Solution: Check the flue and smoke exhaust system to ensure that there is no blockage and the fan is working properly.
Processing steps
Restart the burner: Try to restart the burner and observe whether the red light is still on.
Check the fault code: If the burner is equipped with a fault indication system, check whether there is a specific fault code.
Contact a professional technician: If you cannot determine the problem or solve the fault,
it is recommended to contact a professional technician for inspection and repair.
Timely handling of the red light fault indication on the burner can avoid more serious problems and potential safety hazards.
