  • the invention relates to an air conditioner outdoor unit having a control box removably mounted therein.
  • a well known type of air conditioning system often referred to as a split system, includes separate indoor and outdoor units.
  • the outdoor unit includes a compressor, a heat exchanger, a fan and motor assembly and associated electrical control components.
  • the indoor unit includes a heat exchanger and a fan. In operation, the indoor fan draws air into the indoor unit, through an inlet thereof and forces the air over the indoor heat exchanger and then out of the indoor unit, through an outlet opening therein.
  • the outdoor fan draws air into the outdoor unit, through an inlet, forces that air over the outdoor heat exchanger and then forces that air out of the outdoor unit through an outlet therein.
  • a compressor located in the outdoor unit causes a refrigeration fluid to circulate through and between the indoor/outdoor heat exchangers.
  • the refrigerant absorbs heat from the air passing over that heat exchanger, cooling that air.
  • the outdoor heat exchanger absorbs heat from the refrigerant passing therethrough.
  • the outdoor units of such systems are quite often installed in locations which limit access to the units for both installation and subsequent service.
