How to Repair Jack LaLanne Power Juicers

The Jack LaLanne Power Juicer is a reliable machine when used as directed, but some varieties of fruits and vegetables can cause problems for inexperienced users. Most of these problems can be easily fixed by taking specific steps to clean out the unit's blade and filter assembly. It's not advisable to perform extensive mechanical repairs on this juicer, however; doing so may void the manufacturer's warranty. If unable to repair your juicer to working order, contact customer service for further troubleshooting and repair advice.

Allow the juicer to sit for at least 10 minutes if it shuts down during use. The unit has a built-in thermal cut off safety switch that shuts the mechanism down if it overheats, in order to protect the motor. It should start operating again after a brief cool down.

Turn off the juicer and wait for the blade to stop moving if the juicer starts to overflow. Look inside the spout and remove any blockages to stop the overflow. Insert a toothpick into the spout to loosen the obstruction. This problem may occur if a piece of pulp passes through the filter into the spout.

Place the filter under warm running water to wash it and remove pulp, if the motor begins to sound loud and the juicer starts shaking. Gently scrub the pulp out of the filter with a soft-bristled dish-washing brush. Rinse the filter from the outside, then gently wipe off excess moisture before placing the filter back in the juicer.

Remove residue from between the blade and the receptacle, and any food stuck to the bottom of the pusher, if the motor will not turn on. Check the assembly and reassemble the juicer, if necessary, to make sure it's properly assembled. Place the locking bar into place properly or the machine will not operate.
