An air conditioning appliance includes a heat exchanger disposed within a housing. A compressor is in fluid communication with the heat exchanger. The compressor is operable to circulate refrigerant through the heat exchanger. A fan is disposed within the housing. The fan is operable to flow air over the heat exchanger. A circuit board is disposed within the housing, and a heat sink is mounted to the circuit board. The heat sink positioned such that the fan flows air over the heat sink during operation of the fan. A temperature sensor is disposed at one or both of the heat sink and the circuit board. A controller is in operative communication with the temperature sensor. The controller is configured to receive a signal from the temperature sensor corresponding to a temperature measurement and to activate an alert at least partially in response to the temperature measurement exceeding a temperature limit.

An apparatus management system determines whether temporary operation is possible or not when an abnormality of an apparatus occurs, and performs the temporary operation when possible. The apparatus management system includes a storage unit, an acquisition unit, and an operation content determination unit. The storage unit stores information on repair of the apparatus in association with the abnormality occurring in the apparatus. The acquisition unit acquires the information on the repair of the apparatus and writes the information in the storage unit. The operation content determination unit determines operation content of the temporary operation. The information on the repair of the apparatus includes information on a repair request for the abnormality of the apparatus. The operation content determination unit determines the operation content of the temporary operation in accordance with whether the repair request is present or not.

A UV light disinfectant system is provided that addresses the problems associated with catastrophic failure of the device due to the presence of moisture or corrosive elements getting into the light fixture and damaging internal power connections of the device. Additionally, the UV light disinfectant system is provided with safety features that prevent unintentional exposure of maintenance personnel to the intense UV light used to disinfect air passing through the duct on which the device is mounted.

A heat source unit for an air conditioner that includes a refrigerant circuit includes: an external housing; a cooling heat exchanger disposed in the external housing and that is connected to the refrigerant circuit; a controller that controls the valve; and a first temperature sensor disposed within the external housing. The external housing accommodates: a compressor connected to the refrigerant circuit; a heat source heat exchanger that is connected to the refrigerant circuit and that exchanges heat between a refrigerant circulating in the refrigerant circuit and a heat source; and an electric box. The electric box includes a top and a plurality of side walls; accommodates electrical components that control the air conditioner; and further includes an air passage that comprises an air inlet and an air outlet.

In one embodiment, an overflow sensor assembly of an HVAC unit includes a sensor mounting bracket that is configured to be coupled to a mounting surface of the HVAC unit such that sensor probes of the overflow sensor assembly are suspended within and extend into a condensate drain pan of the HVAC unit. The sensor probes are defined by a sensor element that is coupled to the sensor mounting bracket and a spring that is coupled to the sensor element. The sensor probes are configured to activate an overflow detection circuit when the sensor probes come in contact with condensate fluid collected in the condensate drain pan prior to the condensate fluid overflowing from the condensate drain pan.
