LG TD-C70045E Tumble Dryer drum does not spin

[Juiceloose]

Hi folks,

The dryer powers up ok. I then press the start button to commence drying and the front panel makes a few clicks and then the fan/blade that pumps the water up the drain pipe spins away.

The belt is still attached correctly but main motor however doesn’t spin to turn the drum.

Is the moter dead or is the capacitor. I don’t known enough about capacitors or whether there is any way to check one is defective. 😥

Any advice would be much appreciated.

Cheers,

Steve.

Simple way to tell is if you can hear a hum from the motor (careful). Hum means power to motor, but no “kick” to start it.

That being the case, you’ll need THIS.

Power off before fitting.

Penguin,

Thank you for the quick reply.

The motor appears to be totally silent with no perceiveable hum from it.

The only noise is the the pump from the water drain area spinning away.

Does this mean a new motor rather than capacitor ?

I think a new motor is circa £120. Is there any way to test the motor before I buy a new one assuming it’s more cost effective to replace it rather than buying new dryer.

Thanks again,

Steve.

Re: LG TD-C70045E Tumble Dryer drum does not spin

Hi again,

My neighbour has a spare 10 UF motor run capacitor from Maplin. A link is attached to it here

http://www.maplin.co.uk/Module.aspx?ModuleNo=30309

Problem is that his spare has four spade connectors coming from it whereas the one on my LG dryer only has two.

Can I still use the Maplin spare to test if it’s the capacitor that is faulty. If so, which two of the four connectors do I connect the two leads from the dryer to ??

Cheers,

Steve.

Diagonally opposite should be foolproof.

Thanks for the pointer Penguin.

I changed the capacitor this morning and it made no difference.

When I turn the power on press dry, I hear two clicks from the front panel (guess it’s the printed circuit board) and then the dryer beeps at me continually to clear the filter. After a few seconds the pump which pumps the water to the condensing tank starts up.

I’ve checked the filter a number of times and it is clear.

Is it a printed circuit board fault or likely to be the motor after all.

Is there any way of testing whether the motor is faulty ?

Any suggestions would be gratefully appreciated.

Thanks again.

Test meter and check for resistance through the motor circuits is the next step. From memory, I think that there is a safety cut-out embedded in the windings – if the motor has overheated, this will trip and shut the motor down. You should get approximately 25ohms across the white and blue wires and approximately 22ohms across the blue and red wires.

Hi folks,

Back again in an effort to resolve the problem with my dryer which has been unused since Jan.

I’m not an electrician so wouldn’t know how to test for resistance. I am however mechanically minded so can replace the motor, drain pump, etc. if required.

Unfortunately I don’t know which would be best to replace first ? To recap:

1. The from panel is working and lights up;
2. When I select dry, the panel then flashes ‘clear filter’ after about 20 seconds.
3. The drier drain pump is working fine but the drum will not turn.

If it were your dryer would you replace the main motor or something else first ?

I found the attached website and breakdown of parts http://www.buyspares.co.uk/cgi-bin/cata … 038,111471

Could it be the reset thermostat that is faulty ?

Does anybody know of a parts supplier that would let me buy all the parts I need and then return those that are not required for a refund ?

I’ve tried three local firms all of whom came out to inspect and all said they had never worked on an LG dryer so they would replace part by part until the replaced the faulty item.

On that basis it would be cheaper to buy another dryer with a two year warranty from John Lewis which I’m reluctant to do as the LG dryer is unmarked and hardly used.

Any further suggestions would be very much appreciated.

Cheers.

hi I have the same trouble. replaced motor and the water pump but is still doing it. it can only be the sensor in the front bottom right hand side. ? you can just see it. that`s all that is left for me to try.

erm

have either of you made sure the condenser clips are fully closed?

Thanks Penguin – I have an LG TDC800E and I am pretty sure it’s the motor that is over-heating.

The machine works fine for about 5 or 10 mins and then cuts out. You have to wait 20 mins or so until it will start again. All the controls are ok, it just won’t work when hot.

I have yet to lay my hands on a multimeter to check any resistances… but why would a motor overheat? It ends up super-hot!

There are no ventilation issues… I’ve had the machine apart a few times replacing the belt and the main capacitor, so I know my way round the unit. It is all clean and there’s nothing else wrong as far as I seen.

Any advice? Or is it a new motor??

Thanks in advance.
