Clock and timer work no motor action

One needs to know what the voltage and phase(1 or 3) the unit is and what the power supply is.

Having 9 wires means it is a 3 phase motor.
For 220 to 240 Volts - L1, T1 and T7 go together. L2, T2 and T8 go together. L3, T3 and T9 go together. T4, T5 and T6 go together.

For 440 to 480 Volts - L1 and T1 go together. L2 and T2 go together. L3 and T3 go together. T4 and T7 go together. T5 and T8 go together. T6 and T9 go together.

A failed SCR or triac will not always show visually any sign of failure. Chances are good that is all that is wrong. If mixer had been plugged in when it got wet, that is all it takes. Also check the transient voltage supressors if the chef has them. They would be identified on the circuit board. as TVS or MOV along with a number. Only number to use is the one on the component.

If you can find ratings for the old devices, just matching the basic ratings should do. Just guessing, but the SCRs should be 20 amp and 400 volt, If the old ones are a lower rating than my guess, there is no problem with using the higher ratings, if my guess is low, go with the original's ratings. Manufacturer of device does not matter as long as ratings are at least comparable.

G'day tandjcox842, did you get an answer to your question? If not, and you'd like to offload your mixmaster, I may be intersted. I've got one that works well but is missing parts. Regardz, Perry.

the triac solid-state component on the board for the motor speed control is shorted and you need a new control board, unless you can find an outsource replacement triac,most companies won't sell you parts because of liability issues on internal parts of the unit

Here is how your speed control works:

Speed Control
The speed control of the mixer is attained through the use of a governor assembly mounted at the rear of the control plate assembly.
The electrical circuit is made and broken by the action of the fly ball governor revolving against the control plate.
When the switch lever is moved to an ON position, the position of the control plate with respect to the governor is changed by the action of the switch lever.
Thus, when the control plate is set close to the governor, a relatively low speed of the motor causes the governor to make or break the mixer’s electrical circuit through the control plate.
When the control plate is set farther away, a greater motor speed is required before the governor starts breaking the circuit.
The action of the governor is such that the speed of the motor will remain constant for a given setting of the control plate within certain loads.
After certain loads have been exceeded, the speed of the motor will drop to meet the torque requirements of the given load.
Speed is controlled by the governor and the control plate in conjunction with the phase control.

TRIAC RMS VOLTAGE
BOTH CONTACTS OPEN - 40 VOLTS
ONE CONTACT OPEN - 80 VOLTS
BOTH CONTACTS CLOSED - FULL VOLTAGE
NOTE: The triac regulates the power the motor sees depending on control board contacts.
A device called a triac is a part of the phase control circuit.
This device determines the amount of power the motor sees dependent upon the condition of the control board contacts.
If both contacts are open, about 40 volts RMS is applied to the motor and about 80 volts is applied when either contact is closed and the other is open.
When both contacts are closed, the triac is full on; consequently, full power is applied to the motor. In this way, the speed is controlled.
If the mixer motor begins to run too fast for a
particular speed setting, one or both contacts open, which cuts back on the voltage the motor sees, thus slowing it up.
If the motor operation becomes too slow, one or both contacts will close, applying the needed voltage to the motor to sufficiently increase motor speed.
This is always accomplished through the triac.
The control plate contacts control the triac, and in turn, controls the amount of power supplied to the motor.

If your not good with tools / meters or tedious repairs do NOT attempt this yourself.

Yes. You can do two things. Replace the swith curcuit board or replace the triac/tyristor on the board itself. The last solution requires you to unsolder the triac and loosen it from the heatsink(110v veriosn only. 230v version has no heatsink) and test it with a multimeter to establish if it has failed. (Testing of tracs can be googled.) In eather case you will need to open the casing.

1. remove the base palte by lifting the end opposite to the electric cord.
2. Loosen the bottom power outled slider, without removing it fully
3. unclip the curved plastic retainer in the front and unscrew philips head screw.
4. Work around the edges of the two halves until it comes apart and you are able to free the slider from its return spring.

Replace the cicuit board completely if available. Or resolder a new triac observing the orietation of the pins and reattach to the heatsink by riveting/cliping on or whatever applies to you model. Using heat conductive silicon paste between triac and heatsink is a good idea if it is originally fitted (if white paste residues can be seen). The European 230 v version do not have a heat sink, due to the higher voltage and thus lower current opassing through. If the Euro version, simply replace the triac, trim the pins on the back of the board nad put back in place.

Triacs can be obtained from any electronic componets dealer, as long as you can supply the code stamped on it. The Euro version has code TIC226N, which you can find in any component or manufacturer cross refereanse table. TIC226N basically means a 8 amp triac. Triac is simplified just a sort of ac transistor. The US version I do not have the code for, but it must have a higher ampere rating, thus the heatsink

To replace;
Put all internal componets back in place in the right halve. Put the left halve on top and fit properly by gently pressing together. Fit the screw in the front and the retaining clip. Fit the sliding cover by cliping it back on, observing that the notch for the return spring will meet the spring pin on the right side for it to snap in place. The spring pin can be observed through the slots for the sliding cover. Then insert the base plate reversely of how you removed it.

The problems of these mixers, is that if overloaded the maximum current rating of the triac's may be exceeded. This will cause the triacs to short curcuit and therefore will give full power in any mode.
To avoid the problem, avoide heavy batters, heavy doughs and prolonged high load tasks. Otherwise a very handy smart little mixer that should last for years.

these mixers use an electronic triac(to vary the speed of the mixer) of such low amperage that they run hot normally(to wear OUT), and they don't fuse the units electronics or motor anymore so anything that binds them will short out the triac or motor winding(from heat) and make them inoperable,try and order(what they call) an internal electronic part from these companies and good luck, I tried for 3 months and told them what I needed,they agreed this part was defective, but they wont sell you an internal part(LIABILITY ISSUE) unless your a "company certified technician" go figure, I finally got one through N.T.E.semi-conductors. and my customers HAPPY NOW!!!

the solution its change the capacitor or triac, normaly problems in models A701 or A901 old motors
