Step 6

  • The needle nose pliers will be used to detach the wires.
  • WARNING: Take extra care when using the pliers to detach the wires as both wires and motor terminals are delicate.
  • Use the pliers to “slide” the narrow sides of the motor terminals where the wires are attached. Pinching terminals will make it difficult to remove the wire from the terminal.

Step 7

  • Install new motor.
  • Attach wires to the new motor; make sure that the red wire is inserted back into the positive terminal on the new motor. The positive terminal is denoted by a (+) symbol.
  • The white wire will be inserted back into the negative terminal on the new motor. The negative terminal is denoted by the (-) symbol.
  • Make sure that the motor sits in the lower housing with the two terminals vertically in line, with the positive/red terminal on top.
  • The motor should fit snugly in the lower housing.
