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.
