Previously red was turning on, now it is not turning on. It is very sad to inform that both the leds has been damaged.Hello,
Then the green is probably blown.
What happens when you connect the left pin to + 5 Volts via the resistor and the right pin to ground?

I bought a 37 into 1 sensor kit from aliexpress long time back. I did not find any document user manual. Sure I will replace Led.Hello,
Where did you buy the module?
Perhaps you can buy some bi-color 3 pin led and replace it.
