Everything works good and the LED light is solid, but as soon as it tries to ignite for the first time code 34 pops up, lights up for 2-3 seconds and then flame goes out and goes through the cycles and then shuts off. Ive check the condensation tubes and all are clear of any obstruction. I did some research and all came back to that flame sensor, is burnt out. I'm going to replace it and see what happens.
