This was a bake igniter this Goose chase took me an hour off course.
Sorry it was wrong for this specific model. I have found only 5 models of gas range use the F-11 as no heat. While the electric ranges and wall oven and all other gas ranges use F9 or F19
LRG3021, LRG3091, LRG3093, LRG3095, LRG3097
we will be putting a note at the top of the article for gas ranges to see F9 error and troubleshoot for not heating instead of communication error
