Replacement back rocker switch

Follow these steps:

  • Begin by removing the two screws on the back of the unit that hold the rocker switch in place
  • Store the removed screws in a container or another easily reached place to ensure the screws aren’t lost in the replacement place
  • At this point, it should be possible to replace the switch, however some units may come with tighter wires
  • If your unit has tighter wires, it will be necessary to remove the shell and replace the switch from the inside
  • The unit will have screws around the unit used to hold the shell in place
  • Remove these screws and store them in a safe place
  • Next, remove the unit’s shell
  • This will expose the internal components of the unit
  • On the back of the wire connector there will be green, white and neutral wires
  • We recommend taking a picture at this point that can be used for reference later
  • Remove the bad rocker switch from the unit
  • Align the new rocker switch with the cutouts on the back of the unit
  • Connect the green wire
  • Next, connect the white wire
  • Finally, connect the neutral wire
  • Put the outer shell back onto the unit
  • Replace the screws to the shell
  • The order of the screws does not matter, however make sure the screw lines up with the corresponding hole
  • Replace the two screws to the back rocker switch unit
  • Plug the power cord back into the unit to test that the replacement has been successful
