Shut off the electric to your furnace. the reason that the line is frozen is because of one two things: First there is enough air passing over the A coil on your furnace. Could be dirty filters - closed vents- furnace fan will not run/ stops and starts (bad motor). Second the charge on your a/c unit is low. John

The filter slides out of the bottom of front grill. If there is no room to slide it down and out, remove the 2 screws (1 on each side) then remove front grill to access filter.

Problem could be a short in the wiring, bad thermostat, or issues with the fan control board.
