York furnace with old white Rodgers controller 50E47-070 only sending power to gas valve every so often if power is shut off and turned back on sometimes will fire up Replaced controller with WR 50E47-843 doing the same thing unit don't always send power to gas valve. Any idea what may cause this to happen.
