1. A system to determine one or more corrective actions for one or more refrigeration units, the system comprising:
a server in communication with the one or more refrigeration units, the server comprising a processor coupled to a memory storing instructions executable by the processor and configured to:
generate a plurality of defrosting thermal models based on an analysis of a first set of data, wherein the first set of data comprises a plurality of error signatures indicative of a plurality of self-executing defrost failure instances associated with one or more refrigeration units;
determine, by the plurality of defrosting thermal models, one or more thermal features based on the first set of data;
generate one or more behavior profiles associated with the one or more refrigeration units, wherein the one or more behavior profiles corresponds to one or more causes for the plurality of self-executing defrost failure instances;
define a distinguished causal mapping between the one or more thermal features and the one or more behavior profiles; and
determine one or more corrective actions for each of the plurality of self-executing defrost failure instances associated with one or more refrigeration units based on the distinguished causal mapping.
