Norcold works on AC not propane

I took the fridge propane burner unit off, sanded any rust, cleaned and blew it out with compressed air. I knew the minute I fired it back up that that was the issue, now works great. Flame considerably larger, hotter, even louder. I should have done this before but thought blowing it out with a straw was enough. No. I am still kinda new to this but learning all the time. Did all those other maintenance things on the fridge cooling so I should be good. Thanks for all the feedback.
