Tmesselt,
The furnace is still covered under manufacture warranty for parts and labor. Give the furnace company that installed the furnace a call and tell them you are experiencing a problem with the furnace. LOL, no need to mention you didn't have the problem with the other amps. They may have an AC line filter they can install on the furnace. At any rate they will check to make sure the ignition controller and ignitor is making a good ground connection to the metal frame work of the furnace.
