Fan/Heater Shutdown Messages
“X” represents a number between 1 and 6 in the following message names. Fan/Heater #1 is closest to
the ground and the numbers increase as you move upwards.
0201 - Fan #X Motor Overload
This message indicates that the thermal overloads on either the fan, load, unload or auxiliary motors have
opened, indicating an over current condition. The overloads must be manually reset. The message will
identify which fan overload caused the shutdown.
0202 - Burner #X Housing Temp High-Limit
This error indicates that the temperature high-limit locate on the fan/burner housing opened, indicating an
over temperature condition occurred towards the rear of the fan/heater housing. This control is set at
210°F (99°C) and automatically resets itself when cooled. This can be caused by a grain column plugged
with trash or the meter rolls may be adjusted to run too slowly. Feel the grain columns to determine which
one may be causing the problems. If all the columns are hot to the touch, check the meter roll settings. If
all columns are not hot, examine the column that feels the hottest. Make sure you can see the grain moving
down the column screens.
