I have a Nordyne E2EB-017HB furnace and I cannot get heat in the "Heat and "auto" mode, the blower doesn't come on in this mode but it works great in the A/C mode! The only way I can get heat now is to have it on "Heat" and "Vent" but then it runs all the time. I have since replaced both relays and both contactors and it still doesn't work! I can feel and see the elements heat up and I saw the blower barely start to move but then it kicks off and hear something click! Any help, don't know what else to try except for the Capacitor??? Help???
