Installed new temp board and potentometer on Skillet. While getting old temp probe out found high limit is faulty, will order new limit and heat shield casing. Also almost every screw was rusted out and had to be chiseled or drilled out of bottom panel. Will install new screws. 11/6/19 Installed new limit and temp probe. Put new hardware into bottom panel. Started and cycled unit ok. Burners are burning orange about 3/4 way down. Checked gas pressure it is ok. orifices appear to be the correct size for nat gas. Adjusted ventures and still orange flame. Unit may have rusted out burners unit is too hot at this time to tear down and inspect. Will make estimate to return and inspect burners when unit is not in use.
