what position is te furnace in?..upflow or horizontal?
Thank you, ***** ***** check the limit in blower section?
see parts on page 14 HERE
Thank you, ***** ***** I know you have a meter...
on the board do you see HLO and HLI?
That is for high limit out and high limit in...24v leaves hlo and runs through the limits and returns on hli...if there is 24v on hli then the board is bad...if no 24v on hli then we see if 24v at hlo..
Is filter clean, blower running registers all open?
BUT....if no 24v at hlo we have a board issue
the key will be...when the limit code is flashing...is there 24v on hlo.
Normally limit code is when there is an open in the circuit between hlo and hli
