The following lines were added (+) and removed (-):
On the hot surface ignition gas furnace check the igniter using an Ohm meter to make sure it has resistance. If no resistance is read (open circuit) then the igniter is broken or cracked and needs to be replaced. Also ensure there is a proper ground to the board so that is not "floating" from one leg to the other. There should be 24 volts on a single leg which is what you need on the electronic ignition gas furnace controls.
