Vent (Cooling Fan Blower) Motors; Thermal Limiters - LG LWD3081ST Training Manual

WALL OVEN
The cooling fans can operate at two speeds, based upon temperature. In self-clean mode,
if the oven temperature is above 482° F (250° C), the fans will operate at high speed. If
the temperature is above 212° F (100° C) but below 482° F (250° C), the fans will
operate at low speed. In normal cooking mode, if either oven temperature reaches 212°
F (100° C), the cooling fans will operate at low speed.
The upper thermostat is in front of the upper cooling fan, secured to the base of the
control area by a tab and a screw. It opens at 356° F (180° C) and closes when the
oven cools to 14° F (-10° C).
The lower thermostat is next to the lower oven's bake element. It opens at 320° F
(160° C) and closes when the oven cools to 14° F (-10° C).
