Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem
