If anybody can shed allittile light on things for me i would be ever grateful! I recently replaced a high limit switch on my neighbors furnace, it seemed too fix the problem. Now his furnace runs...flame goes out....then, before the blower shuts down the flame kicks back on! All the while the stat is in a call for heat, it's 70 degrees in the house and i have the stat set at 71, I'm just wondering if this is a characteristic of this furnace or if there is something else wrong? Its a ARMSTRONG 80% high effeceincey furnace. In a nut shell I am just curious if the flame is supposed to kick on and shut off before the stat is satisfied to save on gas usage?
Thanks in advance.......Testytech
