If no flame is sensed in your Rheem Furnace, ensure the flame sense rod is clean; clean it if necessary. Also, check the wire continuity between the flame sense rod and J1, Pin 1 on the I.F.C.
Do not exchange memory cards between furnaces to avoid unexpected operation or loss of heat.
Failure to follow instructions may result in fire, explosion, personal injury, or death.
