    Electric Central Unit Troubleshooting
    I have Central Air and Heat... All Electric Run. Suddenly gone from working fine (all) to... Now the main fan will Not shut off for heat, nor air. When in heat mode it is only blowing all airwhen switche to air and to heat. On Auto and on Fan.
    Took the thermostat unit out fan still runs. Thought it might be a bad thermostat also at first but? Relay?

    Bad timing... cool night of course.

    This is a common problem typically for older units. The fan relay contacts fuse together. Depending on the furnace, you might need a fan control center or with the newer furnaces an entire control board. Nonetheless, a lot of wires are involved.
