5.4 TROUBLESHOOTING SUGGESTIONS
BLENDER MOTOR WILL NOT TURN ON: If the blender motor will not turn on,
try the following:
• Make sure the main power switch on the lower-front panel is turned on.
• Check the house current breaker switch or fuse to make sure it is set to
• the on position.
• Unplug, then re-plug in the power cord.
• Determine if the numbers on the Liquid Crystal Display (LCD) indicator
are lighted. An absence of lighted LCD indicates a lack of power to the
microprocessor.
• Check the LCD
A reading of “OVERTEMP” indicates an overheated condition has been
detected and the motor has been disabled until the unit cools to operating
temperatures. Unplug blender and allow motor to cool for at least 20 minutes.
A reading of “OVERLOAD” indicates an overload on the motor. (Check the
blender jar for blockage.) Turn the blender off for 10 seconds (using the switch)
then turn the blender on again to clear the overload condition.
A reading of “LOW VOLTAGE” indicates not enough voltage coming to the
motor. Turn the blender off. Correct the cause of low voltage. (Normally
caused by more than one appliance drawing power on the same circuit, or by
low power from a power source {brown out}.) Turn the blender on again and
continue operations.
BLADE STOPS: If the “OVERLOAD” condition stops the blender, remove the
blender jar and carefully check for blockage of the blade. If no blockage is
found, replace jar and use the Pulse button on the touchpad to quickly pulse
the blade through the mixture. Once the blade spins freely, a programmed
button may be used.
NOISE LEVEL CHANGES: If the blender noise level has increased significantly
from original levels, determine whether the sound is coming from the motor
base or the jar.
• Motor: Check to see if the excess noise is coming from the motor base.
Remove the jar from the motor base and press cycle number one. Listen
to the motor sound without a jar attached. If it is excessively noisy, contact
Blendtec (international customers contact a Blendtec qualified service agent).
• Jar: Check to see if the excess noise is coming from the jar. Place the jar
back on the base. Run the motor for a few seconds using the Pulse button.
Switch jars back and forth to determine whether the sound changes as
different jars are used. If a jar is excessively noisy, or if the blade assembly
seems loose or sounds “gravelly” when turned by hand, contact Blendtec
