Oven Thermal Cutout
The oven thermal cutout (Cavity TCO) is located on the top side of the oven cavity beside the exhaust duct with a tem-
perature rating of 248°F (120°C) and is
NOT resettable.
Hood Thermal Cutout
This cutout will protect the touch control from excessive heat by turning the vent fan on at low speed. If the surface units
of the range are used for long periods of time heat will build up and could damage the microwave control. In order to pre-
vent this, a thermal cutout is installed on the duct behind the control. This cutout will close (158°F/70°C - vent fan ener-
gized) and open (104°F/40°C - vent fan de-energized) depending on temperature.
Magnetron Thermal Cutout
The magnetron thermal cutout is located above the leads to the magnetrons. It is designed to prevent damage to the
magnetron if an overheated condition develops in the tube due to cooling fan failure, obstructed air ducts, dirty or
blocked air intake. Under normal operation, the magnetron thermal cutout remains closed. However, when abnormally
high temperatures are reached within the magnetron, the magnetron thermal cutout will open at 302°F (150°C) causing
the oven to shut down. After the temperature drops to 140°F (60°C) it will reset and cooking will be able to resume.
Bottom Thermal Cutout
During a fire on the stove the heat could be intense enough to close the Hood Thermal Cutout and force the fan to run.
While at moderate high temperature we do want it to run, however during a fire it is advantageous to NOT have the vent
fan running. So if a fire were to start on the stove top the Bottom Thermal Cutout would open at 248°F (120°C) and re-
move all power to the microwave oven. This cutout is
NOT resettable.
To Test Blower Windings:
1. Disconnect power and remove grill. 2. Open control panel and discharge capacitor.
3. Continuity test across the two wires of the run capacitor should be approximately 120 ohms of resistance. This test
allows you to read across all windings at the same time.

Key short error(10 sec.). Replace assy
control panel or smart board.
Microwave cover assembly
The front of the top cover has flanges that must fit inside the front
frame and vent, and the bottom goes above the bottom cover. Start
with the left side and hold in place with one screw once engaged.
Leave the display loose so you can see that the right side is engaged
properly. Then mount display and the vent, ensuring the vent en-
gages the flange.
