old furnace won't kick off unless set at 80degrees
rheem furnace 20 year old efficiency won't kick on and run unless set at
80. If set at 70 or 75 will not kick on. Any suggestions on what might
be wrong?
Has anyone had an occurrence of a Laser 730 or 731 over firing? The top of the heat chamber and the heat exchanger glow red on high when this occurs....
