Struggling to get IR transmitter working

  Home Assistant platform for controlling IR Air Conditioners via Tasmota IRHVAC command and compatible hardware

This circuit is better, that is use the 5V and not the 3.3V, because the regulator that makes 3.3V for the ESP might not be beefy enough to drive the LED, too. The 100Ω resistor is maybe too much, but I wouldn't remove it completely. Alas you don't know the max. current that your LED can take, so you can't calculate the needed resistor.

  Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

First, try to remove the resistor(i was made an ir remote using the top circuit for ir sender). check the components, maybe one of them are dead. Second, check the gpio and config. Third, maybe the problem is the code. Maybe you should try the original IRRemoteESP8266 library first: You should checkout the original esp8266 ir remote library first: https://github.com/crankyoldgit/IRremoteESP8266 checkout my project: https://github.com/KD-MM2/MHI-AirCon-ESP8266/blob/main/Ver-1_Webserver_IRRemote/TurnOnMitsubishiHeavyAc.ino
