CAVITY THERMAL CUT-OUT TEST
E
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
the temperature of the thermal cut-out reaches approximately 293°F(145°C). An open thermal
cut-out indicates overheating of the oven, exchange the oven thermal cut-out and check inside
of oven cavity and for improper setting of cooking time or operation of control unit. Check for
restricted air flow through the vent holes of the oven cavity, especially the cooling fan and air
guide.
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.
MAGNETRON TEMPERATURE FUSE 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 C/T fuse terminals should indicate a closed circuit unless the
temperature of the cavity temperature fuse reaches approximately 302°F(150°C). An open
cavity temperature fuse indicates overheating of the oven, exchange the cavity temperature
fuse and check inside of oven cavity and for improper setting of cooking time or operation of
control unit. Check for restricted air flow through the vent holes of the oven cavity, especially
the cooling fan and air guide.
If the temperature fuse indicates an open circuit at room temperature, replace temperature
fuse.
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.
