Re: Tumble dryer motor overheating (LG TDC70080E)

All back working perfectly now… thanks.

It was definitely the motor.

I replaced the motor (and the main capacitor – just to be safe) and it’s all fixed. I have a happy wife again!

[FYI… New motor & capacitor was under £50 from SEME nedis…]

😀

ps. if anyone else has to replace a motor – just remember that the fans attached to either end of the motor have opposite threads!

Re: Tumble dryer motor overheating (LG TDC800E)

I found this – I guess this is what I need to do?

To test an appliance motor:
1. Make sure that the power cord wires are disconnected from the motor. If it is easy to do, remove the motor from the appliance, though motors can be tested in place.
2. To test continuity (the flow of electricity) through the motor, set the multimeter on the RX1 scale to measure resistance (in ohms). The multimeter’s internal battery will send a small electrical current through the motor’s wires.
3. Attach one of the multimeter’s probes to the motor’s common lead, usually white.
4. Attach the other probe in turn to each of the other wires on the motor. The probe will be checking to see if it can measure the multimeter’s input signal at the output. A low or moderate reading (in ohms) means the component is okay. A zero or infinite reading means the motor’s windings or another component has a short.
5. If it tests faulty, replace the motor with one of the same type, power rating, and size.

Re: Tumble dryer motor overheating (LG TDC800E)

Thanks – how do I test the continuity of the motor windings?
Is there a particular indicator, eg resistance across two points?
What is a good and/or bad reading?

Thanks in advance.

Penguin45 wrote: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.

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.
