Depending upon your model number you have a defective relay OR a defective heater sequencer which acts as a relay also. You really need to test it with a electric meter to be sure which component is defective. One final note. Be sure your thermostat wire is not damaged or better yet unhook the thermostat wires from the indoor unit itself not the thermostat and then test. You just mentioned you unhooked the stat wires so I figured you disconnected the wires at the thermostat and not the unit itself.
