Does not turn on, all parts seem to be seated correctly. I think it is a safety interlock, but I do not know what to do to make it work. This is a Sharper Image Super Juicer

Faulty motor or the interlock switch is dirty or damage. Try cleaning the contact switch if still not working check the motor if busted.

you have to twist the top round so that the switch is pressed in place so the power can be turned on, from new it takes a few times to get it to click in place this is the safety device so it cannot be turned on by mistake.

They break. The latch arm is one piece, spring and all. So if any part of it is still in the
juicer it's broken. Order a pair from Omega and have them walk you through replacing
them.

Devices these days are safety-ed up the whazzoo (technical term)
The safety catches and hardware all must be correct for these devices to work.
It is possible that a keeper or stationary lock of somekind is still installed preventing the machine from working.
Check the outlet to insure you have power there.
Insure all of the covers are in place and then insure a catch is provided for the output.
Failing all that, return it.

First, check that the switch is in the on position. Then, check that all parts are assembled properly. The unit has a built-in safety device that will not let the motor turn on if not assembled properly. The Power Juicer also has a built-in Thermal Cut Off Safety Switch. If the machine was running, then shut down due to accidental overheating, then there is a 10 minute cooling time before the machine will restart. This helps to protect the motor from seizing.

Hi,

In all juicers there are hidden interlock switches called interlocks for ur protection. Put all the parts properly, so that these switches sense them. then it should work.

Hey if you have not gotten this resolved already, here are some things to consider.
I have the same unit. It will not operate is any little thing is left undone. So, I would recheck all of the assembly to make sure all the attachments are properly and securely attached.  The last part to check which seems rather minute, but will prevent the unit from working, is to check that the pulp catcher is securely snapped in. There is a small lip at the bottom that must clik in just right for the unit to kick on the switch is pressed.  Once the metal arm is in place, give it a whirl.... and let see what happens.
Hope this helps..
Let me know.

There is a little knob on pulp collector that pushes in a switch, probably to assure the unit is assembled before operation. Mine broke off. I opened bottom of unit and used electrical tape to permanently engage the switch. The Juicer now works. I consider it poor construction that such an important part of the operation of the unit is able to break off and poor customer relations that there is no help for this on their web site. I have used it only a handful of times and the unit has mostly been in storage and has not been abused.

Yu have to have the juicer on and properly postioned, it has a little magnet that activates the machine, if it is not on it will not turn on.

I am sorry I might not be able to explain in English very well, but I hope it will help somebody.
In my case, the pulp container was a problem.
when you take out the container, do you see the little(very very small )hole that if you push with something like toothpic it makes sound like "click, click"? I guess when we put the pulp container back, the container is supposed to push the safety button ( bottom area), but I think the part of the container that push the button was broken, and it didn't start,so I just put something small inside the hole before I put the container back to the juicer, so it covers the missing part.
Their customer service doesn't help at all, I waited 1h to talk to somebody, and he couldn't help me. so please check that part.
