Hi ahmed shareef:)

is the wiring for the defrost wired correctly? Is the controller set up correctly?
If yes is your answer your relay in the controller that controls the defost has welded shut and you will need to change the controller.

But I would assume it is either the wiring or the controller settings.

Kind Regards Andy:)

As Andy said, check the wiring.
The heater protection thermostat should cycle the heater so those high temps don't occour.
What is the make and model of the controller?

Have you checked to see that the probes are wired correctly and not cross wired. The evaporator probe should be the one controlling the defrost termination not the cabinet probe.
