Kenmore Microwave Thermostat replacement

:confused: Dear Sir or Madam,

How do I replace cavity thermostat in a Kenmore Microwave (model 665.60652000)? I can see the thermostat from the front of the microwave when I remove the front grill, but it is not clear how to remove and replace the thermostat. On the sears.com (partsdirect) website it is part number 8183697 thermostat. It is part #5 in the Part results for: Air flow diagram. I know the thermostat is bad because when I override it the microwave works.Thank you.
