I am having a couple of problems 1) the furnace will come on blower first before the elements and they sometimes do not heat up and will have to shut off and back to get them to heat up. 2) the elements themselves are a double stack and only half of each element (the very ends) will heat up I don't know what might these 2 problems and if they are related to each other.I have replaced all 4 fuses and that did not seem to help any ideas thank you,Nina.

Hi Nina,

Could be a bad sequencer or an element going bad.

Would need to test for voltage to elements, amp draw for each element and return and supply temp from furnace return grille and nearest supply register to furnace.
