Symptoms
Possible Fault
Low Kiln Temperature
Normal Water Extraction
1. As long as water extraction is normal,
kiln temperature cannot be too low. In
fact, the lower the temperature the better
the wood quality. The insulation
thickness’ in Table 1 provides for 50ºF
(28ºC) temperature rise over the outside
temperature at continuous drying control
setting. Lower settings will give lower
temperature rise.
Mold or Mildew on Lumber 1. This condition is not harmful to the
lumber, but can be minimized with
improved airflow or higher kiln
temperature.
Bottom Layer or Two of Lumber Not Dry 1. This is caused by large temperature
differences (greater than 5ºF) from top to
bottom of the kiln. Greater airflow or a
better door seal will usually improve this.
Temperature in Kiln Continues to Rise
Above Thermostat Setting
**DO NOT LOWER THERMOSTAT
SETTING**
1. Thermometer on controller may need
to be adjusted. If extraction maintains at
normal rate, check temperature in the
kiln with thermometer at the base of the
dryer. If the temperature reads lower or
higher than the thermometer needle on
the controller, call Ebac for adjustment
procedure.
2. If temperature reads the same and
extraction ceases or slows substantially,
you may have a “temporary over-
insulation situation”. Simply peel back a
corner of insulation from the top of you
kiln chamber. If this does not remedy
the situation in 24 hours, call Ebac.
