Methods of preventing freezing of relays in electrical components

A method of preventing freezing of relays in an electrical component comprising:

• monitoring a temperature of a contact within a relay with a first thermocouple located on the contact;
• concurrently monitoring ambient temperature within the relay with a second thermocouple;
• operating the electrical component in a sub-zero temperature and high humidity condition during temperature monitoring;
• cooling down of the electrical component un-powered in the sub-zero temperature and high humidity condition during temperature monitoring;
• and
• determining a freeze potential of the relay by plotting a temperature cross-over curve, wherein both the ambient temperature and the temperature of the contact are plotted during the operating and the cooling down, wherein if the temperature of the contact and the ambient temperature cross on the temperature cross-over curve, a high freeze potential of the relay is determined and if the temperature of the contact and the ambient temperature do not cross on the temperature cross-over curve, a low freeze potential of the relay is determined.
