Check for Proper Ventilation:
1. The unit will not function properly if there is not
sufficient air space (4 inches minimum on back and
sides).
2.
Make sure that the filter (CFB2 and CFB3 only) is
clean and that all ventilation grills are not blocked or
dirty. See the CLEANING section.
3. Make sure that the unit is not close to sources of
heat that could affect proper operation (heaters,
cooking grills, etc.).
