Hello I have a P-30 Whitfield. My problem is that the stove goes out after 30 minutes or I should say the pellet stop coming down. Then the stove goes into a fault. I have already replaced the photo eye and did the relocation as well. I have replace the limit disc. When I had the stove outside running to see if the problem went away at that time it did. Then I brought the stove back in side and hooked it up.Same problem. There is only two more part I can replace control board and the back flow switch. Thank you for your time
