  If your Guardian Plus Air Cleaner doesn't start, first check the breaker or fuse in the main distribution panel. Then, verify that there is 120V at the electrical outlet. Ensure that the unit's main switch is properly set to either the Normal or Boost position. If a wall control is connected, disconnect the control wire from the unit and then ensure the main switch is properly set.
