e. If you substituted a dome drive, turn on power. If the unit operates, the original
dome drive is bad. Return it to the factory. If the unit still does not operate, then
the interconnect board is bad. Return the back box electronic assembly to the

BACK BOX ELECTRONIC ASSEMBLY REMOVAL
1. Turn off power.
2. Open the interconnect door and disconnect all wiring to the back box.

back box receptacle will drop down. You may have to move the open interconnect
door past 90 degrees vertical toward the side of the back box to release the door from
the built-in grounding strip (and free the interconnect back box receptacle).
4. Remove the interconnect back box receptacle with the electronic components from the
