Do this. Remove the platter mat, and find the motor pulley through the holes on the platter. Set it up to play, but don't put a record on it. The platter should be slowly spinning from your description. These platters should have holes to pull the platter off to access the belt. turn the platter until it reaches the motor pulley. If you can stop just the platter, while slowly touching the pulley, the motor should stop as well. If the belt is slipping with the platter stopped, the belt is bad.

    There are no holes in a Thorens platter. It is not a cheap pioneer or kenwood. There are two platters, when you lift off the outer platter you clearly see the small inner platter with the belt and pulley. Please don't listen to those who never owned a Thorens. You may harm the machine.

    Even if this unit has two platters, as you say, if you remove the top platter, you will have access to change the belt. At that point, please refer back to my earlier posted platter.Thank you.t

Do your Thorens table the biggest favor you can by first contacting STS Turntables at classicthorens.com. Their Swiss trained and mentored tech is by far the best in the world in my opinion at Thorens vintage repair/restoration. They are building a custom TD-124 for me and I am amazed at the knowledge and customer service this company demonstrates.

If you can turn the platter easily by hand, then so should the motor. You can also disconect the power leads to the motor and hook up a PP9 9 volt battery to it. If it\'s slow and easily stopped from rotating then there\'s nothing wrong with the power to the motor and the motor is bad!

SOURCE: technic 1200 mk2 turntable wont spin

need to know if it powers up. Does it try to spin, do you hear it trying to spin? More than likely the on/off switch went bad. No, I am not referring to the ON/OFF knob. THere is a switch this engages when turned. The part is S601. You might also want to replace the Start/Stop switch as well. If neither work, then the issue is on the main PC board, and probably IC101, or IC201 with the problem. At this stage, you will have to have a service tech look at your unit.

SOURCE: Dual 1228 turntable platter not spinning, the motor will not turn

This particular unit uses an idler wheel to drive the table. Remove the platter and check the rubber wheel. It may be dirty, or just dry and slick. This part may need to be replaced or treated.

SOURCE: I have an old Thorens TD125 Mk2 turntable with a

HELLO
Right, first off I don't know the deck very well in question....this is more advisory. Have a look on the internet at www.theanalogdept.com and you will find many things regarding THORENS decks including links to other websites. Myself, I own a Thorens TD166mk2.
Judging by your posting it SOUNDS like something needs lubricating - not quite sure what though - all depends on where you had it stored. If it was just put into an attic, remember that heat and cold will affect the deck in loft spaces significantly.
If you have any doubts about looking at the deck yourself, then take it to a reputable hifi dealership for servicing.

There's either a lot of grease or something in the motor, or the motor control circuit has a fault on it. Try spraying the motor with Servisol Video 40 first. (available from Maplin UK or Radio Shack USA).

AL-A1 turntable won t turn


take the platter & belt back off, then check to see if the motor spins, if it does the belts the wrong size or put on wrong, if it doesn't spin then you better get your butter & jam out, to put on your toast.

My Thorens TD150 MK2 Phono Turntable Motor will not run or spin with the belt on but will turn without the belt on.What is wrong.


First replace the 0.33 microfarrad capacitor take a 0.47 with the same or higher voltage of a good quality and lubricate the motor top and bottom spindle bearings
sintered bronze buses with a ceramic high quality lubricant spray tecflow or other brand .
The best is to disassemble the motor only the top bearing is never enough also to control the both bearings.

My thorens TD280mkIV won't spin. I've checked the power supply, 16V is getting to motor. When I hit start switch, motor twitches but doesn't spin. I've oiled motor, but turning spindle still feels...


It seems a bit high 16 volts, most motors run at 12 or lower. Sometimes it says the voltage on it! There's one certain way to check if a dc motor is working. Disconect it an stick a 9 volt battery on it. If it doesn't turn with that it's dead!

My turn tabel isnt spinning


The drive belt has come off. Open the lid. Remove the rubber mat on the platter. Remove the C-shaped clip from the center of the turntable. Lift the platter up and off. Find the flat rubber band that connects platter and the motor. Plug it in and verify that the motor turns when you press power, then standby, then phono.If the motor spins, unplug power and place the drive belt on the underside of the platter. This is not easy, but it can be done with patience. Then put the C-clip back on and replace the mat. Congrats!.

Thorens TD 126 Mark III - Motor will not run with belt attached


Maybe next time you might turn it OFF before handling the belt.

Try this with power off - manually rotate the turntable and look for where drag might be. You should be able to feel the drag. It is possible you didn't route the belt properly.

Turntable will not turn


spin the motor between your fingers, sometimes they develope a 'dead spot' if it comes to life let it run for a few hours, this may fix it forever.

Well, with a turntable that old, if it hasn't been restored it likely needs to be. Could be the power cord, the motor or the clutch.
