SOURCE: Furnace blower never blows.
it sounds more like the flame sensor ( a metal rod that is by the burners with a wire going to it and it has a ceramic base). you can try cleaning the rod and if that doesnt work they are not to expensive.

SOURCE: Furnace will not heat.
Most of the Lennox G-16s that I have repaired were having problems with the gray Penn-Johnson Piggyback igniton control module.
This is best repaired by replacing the spark module. Sometimes it may be neccesary to replace the gas valve also. Lennox updated to a ROBERTSHAW ignition system. Honeywell can also be used.
Also check that there is no water in the pressure switch or tube.
Hope this helps.

Yes. If the high limit is tripped, the furnace will bring on the fan continuously until the limit resets. Often, they will not reset if tripped repeatedly. If the furnace is too large for your application, you probably are not able to move enough air to keep the heat exchanger cool enough.
