Look at the link attached, the defrost t-stat is #38 (thermo bimetal). Clips to the coil, looks like a round device with wires on it. Defrost t-stat is normally closed to allow power to the heat element and opens when hot enough to stop the defrost cycle. Heat element #43 should not test "open" with a multi meter, there should be some Ohm value there to show it's good. The defrost timer could be a clock type or circuit board type, page through the links diagrams and you should be able to see where it is physically located in your particular unit.
