    Backup heat stays on
    Put system in backup mode because temps outside were below 32.

    Next morning wife put system back into heat mode for the day.

    Came home from work and found the house temp 76.

    Went down and put amp meter around each coil wire and found one heating coil was still on

    Is this a relay problem or possibly a thermostat problem or something else

    The sequencer is stuck. High voltage problem, not the thermostat.
