Secondary Limit Control
The secondary limit control is located on the top of the blower
scroll assembly. This control opens when elevated
temperatures are sensed. Elevated temperatures at the
control are normally caused by blower failure. The reason for
the opening should be determined and repaired prior to
resetting.
If the power to the unit is interrupted during the heating cycle,
it may cause the secondary limit to trip. Once the blower
compartment temperature drops below the limit reset
temperature, the limit will automatically reset.
