Reasons And Solutions for The Red Light But Not Green Light After Ignition of The Combustion Engine

1、 The reason why the red light of the combustion engine lights up

The red light on the combustion engine usually indicates one of the following situations:

1. Insufficient fuel supply: If the fuel supply used by the combustion engine is insufficient, or if there is blockage in the fuel pipeline, it will cause the combustion engine to be unable to work properly, resulting in the red light being on.

2. Igniter malfunction: If there is a malfunction in the igniter or if the igniter connection is unstable, it can also cause the red light to light up. In this case, the ignition effect of the combustion engine is not good, making it difficult to ignite the fuel, resulting in the red light coming on.

3. Heat exchanger malfunction: If there is a malfunction in the heat exchanger, it can cause the temperature of the combustion engine to rise while burning fuel, sometimes normal, sometimes abnormal, and thus cause the red light to light up.

2、 The reason why the green light of the combustion engine does not light up

If the green light of the combustion engine is not on, there may be the following situations:

1. Fan malfunction: If the fan of the combustion engine malfunctions and is not sufficient to discharge fuel smoke, it can also cause the green light to not light up.

2. Safety device malfunction: The combustion engine has multiple safety device detections. If any safety device malfunctions, it may cause the green light to not light up.

3. Power failure: When there is a problem with the power supply connected to the combustion engine, it can also cause the green light to not light up.

3、 How to solve the problem of red light not green light after ignition of the combustion engine

If the combustion engine lights up red but not green after ignition, the following steps can be tried to solve the problem:

1. Check if the fuel supply is normal: Check if the fuel pipeline of the combustion engine is blocked, and also check if the fuel supply is sufficient.

2. Check if the igniter is functioning properly: Check if the igniter is properly connected, identify the fault, and repair it.

3. Check if the heat exchanger is functioning properly: Check if the heat exchanger is blocked, if there are any faults, and repair them.

4. Check if the fan is working properly: Check if the fan is running properly, get rid of the fault, and perform a new ignition test.

5. Check if the safety device is normal: If there is a malfunction in the safety device of the combustion engine, professional personnel need to carry out maintenance, and the specific situation needs to be determined according to the specific situation.

6. Check if the power supply is normal: If there is a fault in the power supply, it needs to be resolved first before conducting an ignition test.

In summary, if the combustion engine is ignited and the red light is on but not the green light, it usually indicates a malfunction and requires maintenance. If you cannot troubleshoot the problem yourself, you need to seek professional assistance.
