You would need to find out what accomplishes the defrosting. Common reasons for defrost failure include:
1. A heating element for that purpose has burned out.
2. A mechanical timer used to switch the heating element on and off (say once for one hour every 12 hours) has stopped running.
A schematic diagram, either in the manual or on the inside of a panel of the unit, would show the defrost mechanism and/or components.
Tornado victims: Do not rush to rebuild. Take your time and look for and get a good contractor. Or consider selling the property and moving to a home that is ready to live in.
