Lennox G51MP Elite Series


I have a Lennox G51MP furnace that is not running properly.
The LED diagnostic code Is reading an alternating slow flash which translates to: Watchguard--Burners failed to ignite, limit open longer than 3 minutes, or flame sense lost 5 times in one heating cycle.
Any help with this is appreciated.

Lennox G51MP Elite Series Issue

Lennox stuck in Watchguard Mode

Ren: Now listen, Cadet. I've got a job for you. See this button? Ren: Don't touch it! It's the History Eraser button, you fool! Stimpy: So what'll happen? Ren: That's just it. We don't know. Maybe something bad, maybe something good. I guess we'll never know, 'cause you're going to guard it. You won't touch it, will you?
