SOURCE: my vitamixer's variable speed switch is stuck on

This problem sounds like failure of the Variable Speed Potentiometer component. Here is the most helpful Fixya article so far: http://www.fixya.com/support/t6032529-need_replace_speed_control
I have the same problem right now and don't want to pay ridiculously high prices for a small electronic component.
So far, this is as far as I've gotten in researching replacement parts:Vitamix Part #015955
Partstown sells #15955 for $23.39 on their website but I found out they charge $15 for shipping -- for a one-ounce piece of electronics. I won't pay to be ripped off on shipping so I won't buy one from Partstown until I've exhausted less-expensive suppliers. Here is the product at Partstown: http://www.partstown.com/vita_mix/vm15955

Another Fixya contributor, Robert Sadler, said he was going to try a generic potentiometer from Mouser.com. His descriptions are kind of vague for me. I'm not an electronics expert so I'm not very confident I can interperet his description:

"If you are comfortable with soldering, you can get a replacement part at Mouser.com. The pot is a 5k "slimline" made by Bourns, however looking inside the cover it looks like most pots would fit. I ordered one for a bit over $5 and will update when I get it with how it worked. You would just have to solder the existing wires to it." -Robert Sadler

I have no problem soldering the existing wires onto a new component but I don't really know what would be an appropriate potentiometer to buy as a replacement from an electronics supplier. In addition, Mouser's website seems to sell potentiometers only in bulk quantities of 5, 6, 12, or 45 items at a time. I just want one.

If anyone knows how to interpret Robert Sadler's comments, or has actually done this repair, please post below. I'm sure quite a few people would benefit from a high-quality repair at a low component cost.

What does OL2 fault in KEB drive indicate?


Too much current is being required with the motor shaft not rotating. This is most likely a parameter adjustment issue with the motor data, torque limits and protective functions.

Possible motor issue as well.

KEB 07 F5 Error code E. Puch what will cause this error and how do i clear it


E.puch means that at power up the control card did recognized the power stage as different than last time it powered up.

This is normal when the control card is changed. If the control card has not been changed, there is a problem between the power stage and the control card.

Initialize the value at sy.03 to reset the error.

Can the write speed of the internal cd burner be changed on the tascam 2488 mk ii to produce a more accurate audio cd . if not how is the write speed determined .thanks Andy


The actual disc speed in the unit has nothing to do with the speed that a CD plays back.

Read page 68 of your user manual for variable speed and pitch setup and changing.

A question? I have a drive COMBIVERT F5 and shows me the screen is pure 00000 and does nothing but think what went wrong?


Push the function button on the display and see if it changes to something different.

If it stays at 00000 then there is a problem with the inverter.

Power steering failure


Problems with electronic variable-assist systems include all of the same things that can go wrong with a conventional power steering system (leaks, center wear in the steering gears, pump & hose failures, etc.), plus problems with the control electronics including the vehicle speed sensor circuit, the solenoid valve and control module. Accurate diagnosis, therefore, is essential to minimize warranty returns. Most of these systems provide diagnostic fault codes that can be accessed with a voltmeter, test light or scan tool to pinpoint the nature of the fault (if the fault is electronic rather than mechanical or hydraulic).

If power to the solenoid or control valve actuator is lost, the valve keeps the bypass circuit closed so full power assist is provided under all driving conditions. The only indication of trouble, therefore, might be a loss of road feel and/or increased steering sensitivity at highway speeds.

It’s important to remember that variable-rate power steering only reduces the amount of pressure that reaches the steering gear at higher road speeds. The only way it could reduce power assist at low speed would be in the unlikely event the actuator or solenoid valve failed in the open position. This could cause a noticeable reduction or loss of power assist.

On GM’s Magnasteer racks, loss of current to the magnetic coils would cause a loss of power assist at low speed. Coil resistance can be checked with an ohmmeter, and should read about two ohms. An infinite (open) reading indicates a bad coil (requires replacing the rack since the coils are not serviceable). Checking for shorts between both sides of the coil assembly and rack housing is also recommended.

The system does have self-diagnostic capability, but there is only one fault code: C1241 (Magnasteer circuit malfunction). The code is set if the module detects an open or a short in the coil circuit. If this code is present, the Magnasteer system is disabled and will not vary the steering effort as vehicle speed changes. The C1241 body code can be read with a Tech 2 or equivalent scan tool. The Tech 2 tool can also be used to perform a Magnasteer function test. The test varies the current to the coil so you can check for a change in steering effort when turning the steering wheel.

Replacement racks for variable-assist power steering applications are available with or without an EVO control solenoid. As long as the original EVO control solenoid is working OK, it can be removed and installed on the replacement rack to save your customer a few bucks. There’s no need to replace the whole rack if only the EVO solenoid valve is defective.

On GM Magnasteer applications, the whole rack must be replaced if the rack or control unit is defective because the Magnasteer unit is part of the rack. Handle with care because the permanent magnets inside the Magnasteer valve assembly and connector are fragile and can be easily damaged.

Good luck and hope this helps you understand the Steering system on your STS to save you some money on what to look for and what to look out for if your going to have a auto shop repair it. Such as the Valve is replaceable and it may just be a bad wire connection.
