THERMAL CUT-OUT (TOP HEATER) TEST
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. A continuity check across the thermal cut-out terminals should indicate a closed circuit unless
thermal cut-out reaches 338°F (170°C). The thermal cut-out resets automatically at
approximately 311°F (155°C). If the thermal cut-out has operated under the normal condition,
replace the thermal cut-out. An open thermal cut-out indicates overheating of the top heating
element unit. Check for restricted air flow to the top heat element unit through the vent holes of
the oven cavity, especially the heater duct upper and convection fan.
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect the power supply cord after the outer case is installed.
8. Run the oven and check all functions.
THERMAL CUT-OUT (SIDE HEATER) TEST
1. Disconnect power supply cord, and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. A continuity check across the thermal cut-out terminals should indicate a closed circuit unless
the temperature of the thermal cut-out reaches approximately 302°F(150°C). The thermal
cut-out resets automatically at approximately 266°F(130°C). If thermal cut-out has opened
under normal condition, replace the same item as in the parts list. An open thermal cut-out
indicates overheating of the side heating element unit. Check for restricted air flow to the side
heat element unit through the vent holes of the oven cavity, especially the heater duct left and
convection fan.
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect power supply cord after the outer case is installed.
8. Run oven and check all functions.
If the thermal cut-out indicates open circuit at room temperature, replace the thermal cut-out.
If the thermal cut-out indicates open circuit at room temperature, replace the thermal cut-out.
