HI im John i will help you with the problem.
Open the freezer door and reach in to the back panel an you feel frost on that panel please.
Remove the bottom front kick plater you will see this timer on the right turn the small cog on the timer slowly till it kicks off then wait 15 min to see if the frost starts to melt if it does replace this defrost timer it should fix the problem.
The defrost timers in line with the defrost thermostat replace this thermostat I should have told you to replace both parts it common for them to both fail.
