Abstract: A control circuit for a room air conditioner includes two temperature sensing devices and an associated switch network which operate to de-energize the evaporator fan upon de-energization of the compressor but, as the temperature of the room air subsequently rises, cause the evaporator fan to be energized prior to re-energization of the compressor. The evaporator housing and temperature sensing devices are arranged such that during operation of the evaporator fan one of the devices senses the temperature of air entering the evaporator while the other senses the temperature of air leaving the evaporator, but during periods when the evaporator fan is off the device which formerly sensed the temperature of air leaving the evaporator operates to sense the temperature of room air.

Abstract: A diagnostic system for use with refrigeration apparatus and the like for selectively indicating the operability condition of different electrical components thereof. The indicating apparatus is mounted to the refrigeration apparatus and includes a selector switch for selectively placing the apparatus in a normal operation mode or in a test mode. A lamp provided for normal illumination of the interior of the refrigeration apparatus cabinet is selectively utilized by the testing apparatus as an indicator of the operability condition of the selected component.

Abstract: a refrigerated appliance having a cabinet defining a pair of cavities and an apparatus for refrigerating one of the cavities. The refrigerated cavity is provided with doors for selectively closing the refrigerated cavity. The other of the cavities defines an opening and is adapted to receive a freestanding microwave oven having an integral door. The open cavity may be provided with a trim for adapting the cavity to any one of a plurality of different microwave ovens electrically disposed therein. The trim may define a vent for providing the microwave oven with cooling air flow circulation. The refrigeration apparatus may define a freestanding cabinet with the microwave oven defining a freestanding oven carried on a horizontal support wall at the top of the refrigeration space.
