thermostat needs to be increased if the error is displayed frequently.

Drying Chamber Overflow
The grain level in the drying chamber has reached the Drying Chamber Overflow Rotary switch. Grain will
have to be dumped from the drying chamber to the storage chamber before the unit can be restarted. This
error indicates that either the Drying Chamber High Level Rotary switch is faulty or the time on the
High Level switch delay needs to be lowered.

located 3' below the fan and heater(s). Grain will have to be removed from the storage chamber before
the unit can be restarted.

The Storage Chamber High Level switch has failed. Both the normally open and the normally closed sides
of the switch are in the same state.

The out of grain timer has ran for longer than it was set. Either you are out of grain or the fill system is
filling to slow.
