Problem Possible Causes and Solutions
The display shows
err 6 and
flashes SenSor Defective control sensor. The control sensor may be shorted, open or otherwise
damaged. Perform the Factory Reset Sequence described above. If this does not fix

Service Center.
RF energy emissions. If the display changes more than twice the normal display
deviation, another unit in the area could be emitting RF energy. Move the unit to a
different location and rotate the unit again. If the temperature is correct in this new
area or deviates differently than the first are, RF energy is present in the room. If you
have to perform the test in the effected area, use the comparison test to eliminate
any possible errors.
