Goblin Teasmade 860 Clock problem

[Herald1360]

As the title says....

I've got one of these I was given a few years ago and filed in the back of a kitchen cabinet. It's been exhumed since I have a new potential old lady owner, but upon my trying it out the clock doesn't run. The teamaking side works fine in manual mode.

I've got as far as taking the bottom off and establishing that the clock's coil has continuity but further dismantling to get at the movement looks "interesting". Any pointers as to how to get in without breaking anything? The whole shebang looks a lot flimsier and cheaper than earlier models shown in old threads here.

Photo attached showing view from underneath of the clock assembly- can the motor unit be withdrawn by simply (!?) undoing the two visible screws or am I looking at a rather more interesting time?

Hi Herald1360, If you check the label on the motor it should give a working voltage, possibly around 100v ac. Check with your ac voltmeter to see if it is present across the motor winding. I would suggest that if you have any volts it won't be as the label rating due to the 2 Watt resistor having gone high resistance or even open circuit.

[Herald1360]

Not so simple, unfortunately. Coil has continuity, resistor is in spec and voltage across resistor is around 130V. Whatever's going on is not a simple electrical fault.

I was hoping for a "been there, done that" response but I'll carry on regardless if I have to.

The motor looks like it comes off with two screws.
I would take it out but not bother undoing the wires and check that it runs freely by hand and them apply power to see if it spins.
If it is stiff put a drop of motor oil on each of the two bushes making sure none goes on anything that is made of plastic and leave it overnight.
Wipe off any remaining oil and put it back in.

Very true, Chris. Ours has been working every day since the 1970's.

Do as as Refugee says first; best idea. Unfortunately the plastic wheels do tend to suffer after a while ...

Got the motor out- it just vibrates when powered and can't be persuaded to run even when flicked in either direction.


The spindle feels a bit sticky and the bushes (bearings?) look to be plastic.



There's no obvious way into it either. It looks to be pressed together.


It's a Sonceboz 912 R 086. The company seems to exist making stepper motors for chart drives and car instrument panels and other mechatronics stuff but I can find no reference to an old clock motor.



Fix looks unlikely

The motor should free up with a tiny drop of oil left to soak in over night.

Looks like it did!


Clock runs OK now and teamaking system is triggered by alarm contacts, steam pressure in kettle transfers boiling water into the teapot then the kettle tray switch trips the heater off and the light and buzzer on.


The "key" to getting the front panel out was to release five spring clip retainers around the edges of the assembly. Not the easiest of jobs- some of them were hard to get at and a fair amount of force was required too.


Pic shows one of the clips. The loop at one end has to be bent up enough to allow the clip to be moved inwards to release the panel. Putting the panel back and locking the clips again was a LOT easier.
