Question

I have Rheem model RGVG 07 NAMGR and last week turned the heat on, it worked then the fan would not shut off and continued to blow cold air. I turned the power off then on and the furnace continued to blow cold air. I unplugged the all the thermostat wires at the unit thinking it may have been a short, when the power is on the fan continues to blow. I took the board out and checked all the relays. None appear to be stuck. I am out of ideals please help.

A new board was put in in 2003 and the serial number is F2993 3236, I belive the unit was installed in 1993-1995, before I bought the house.
Thanks

Hi,

That usually indicates a high limit switch being open, look for these types of devices and reset them, they are located around the burner rack.

let me know,
