Samsung SBS Refrigerator Incorrect positioning of Thermal Fuse  HOME
 
Fault
 
Appliance does not defrost.
 
Cause
 

On a previous repair when the thermal fuse was replaced, it may have been fitted incorrectly.

This was due to a fault with the replacement thermal fuse sent. Some thermal fuses were sent without a protective sleeve.

Therefore if the replacement thermal fuse was secured to close to the defrost heater then it would cause the thermal fuse to operate prematurely.

Cure
 
Order a new thermal fuse GC No. 673 879 and when fitting ensure that it is attached to the evaporator and not the defrost heater.
