Last year the screw that holds the clip to hold in the burner tube snapped off flush on the inside of the stove. Under warranty the dealer just stuffed self tappers in each side "wedging" the tube in place. After 1 month of continuous burning the "fix" failed. What is the correct way to fox this besides drilling out the screw. Everytime I load the stove for the night and a piece of wood hits it and I have a 500 degree tube that falls out that I need to grab and put back in. The stove is 3 years old.
