Re: Furnace blows cold
what type furnace do u have ??? most sail switches can only be got at by pulling the furnace ,, mine had the same prob ,, i have a rexhall also ,, but the fin on my sail switch fell off ,, fixed that ,, but still no hot air ,, i guess i am looking at replacing the gas valve next ,, i'll get to that in about another 3 yrs or so ,, i don;t need the furnace ,, i camp when it's warm ,, and if i do need heat ,, i have the heat strips in the roof units
