    WARNING TO SERVICE TECHNICIANS To avoid possible exposure to microwave ra- diation or energy, visually check the oven for damage to the door and door seal before operating the oven. Use your microwave sur- vey meter to check the amount of leakage before servicing.
  • Page 7 Whirlpool microwave ovens have a monitoring system designed to assure proper operation of the safety interlock systems. The interlock monitor switch will immediately cause the oven fuse to blow if the door is opened while the following combined failure exists:...
  • Page 8 CAUTION EQUIPMENT • Electromagnetic energy leakage monitor (NARDA 8100B, HOLADAY H1501). • 600 ml glass beaker. • Glass thermometer 100°C or 212°F. TEST On every service call, checks for microwave energy emission must be made according to the following manner. Remove the cooking rack from the oven cavity, if the microwave oven is so equipped.

  • Page 10 The normally-closed (N.C.) contacts of relay 4 provide a potential circuit for the Base Thermal Fuse. If the base of the oven exceeds 133˚F, the thermal fuse contacts close, and a circuit for the low-speed side of the blower motor is completed, which turns the motor on. The low-speed blower will operate until the base temperature drops below 104˚F and opens the thermal fuse contacts, and turns off.
