    That Coleman series does not use a fan and limit combo control like a normal furnace. On of the heat sequencers turns the fan on in the heat mode after a very slight delay. There could also be a relay that bypasses that control so the blower will operate with out the heat or A/C on.

    Relay part number 3110-3301

    Sequencer part number 3115-3571

    You will need to test these items to see which one is defective.
