Vacuum cleaner Electrolux ZSC69FD2 - Speed controller 2193995-10

Question

Hello, I need to replace the potentiometer in the speed controller 2193995-10 (marked on the photo) in the Electrolux ZSC69FD2 vacuum cleaner. I have not found his mark anywhere, so I am looking for information about which potentiometer is and if you can get one anywhere. Thank you in advance...

No markings underneath?

Hello, Desolder and measure with an ohmmeter the resistance value between the two upper legs.

gumisie · Answer

Hello. Perhaps there would be more information, something like this: why do you claim that this potentiometer is damaged and needs to be replaced? (description of the fault). The picture is not very clear, maybe this one blue the frame is what you are looking for. Best regards.

szycha82 · Answer

When adjusting the speed, the engine did not even start - after treating the potentiometer, spray contact catches and gives different engine speeds - that's why it seems to me that the potentiometer is on the side. In the frame you write about is only a tiny logo and the inscription SPAIN.

Thanks for the answer. In this situation, do what your colleagues suggested: 1. 2. Best regards.

Probably 2.2M? or 4.7M?. What you find mechanically fitting, so good

szycha82 · Answer

Thanks for all the tips. For now I am away, I will do it after returning and write what exactly was the potentiometer. best regards

szycha82 · Answer

No markings underneath. I measured the upper 2 legs after desoldering and it is 21.52k?. Any ideas where such a potentiometer will get or if it is impossible then maybe some alternative? Thanks in advance

miecho18 · Answer

Buy a 22k? potentiometer.

szycha82 · Answer

The question is where to get one - I searched and I can't find one. I measured it with a caliper and it's 14mmx14mm so it's ACP series CA14 and I can't find one.

gumisie · Answer

Then set the slider (3) of the potentiometer to the middle position and measure its resistance: 1 (upper left) - 3 (lower), 3 (lower) - 2 (upper right). To initially determine the efficiency of the potentiometer, connect the meter on this principle [(3 - 1), (3 - 2)] by turning the knob we observe the ohmmeter indications.

szycha82 · Answer

3-2 goes from 0.6k to 22.5k (but along the way has from time to time strange jumps to 30k 40k or OL) 3-1 goes from 21.59k to 0.7k (similarly as above there are breaks ) I treated it with contact spray several times because before it was much worse. Added after 17 [hours] 58 [minutes]: I got this sprayed potentiometer on my contact and sprayed it for a long time - there is a big improvement. The only thing is that now the adjustment knob from the vacuum cleaner works from the maximum down but the vacuum cleaner does not turn off - it's difficult, it works. Thank you all for your help.

I suggest you visit the Czech forum link there is a diagram and some useful information on the subject presented. The system is controlled by the MC9S08QD4 series microcontroller / MQD4C replacement that is used in these vacuum cleaners.

Hello. I have a similar problem and I'm wondering if you have solved yours. I wanted to give my friend's vacuum cleaner to the office and decided to refresh it a bit. I stripped to bare plastics, which I washed and dried. After folding, the vacuum cleaner works with full power after inserting the plug into the 230 V socket. The power regulator does not work in any position, i.e. in every position the engine works at maximum speed. Turning it does nothing. Any advice? Vacuum cleaner ZAM6250 Electrolux. Before dismantling everything revolved as it should be. Well, not really. Thus, the regulator worked, turned the engine on, increased / decreased its revs, but when working in the MAX position, without any apparent reason, it was able to reduce the revs to various values, as if someone were playing with the knob gently and only then again its physical intervention (knob) intervention and setting in pos. MAX resulted in work at full capacity, but the situation liked to repeat itself. In any case, he turned the engine on and off, and now as if it (the regulator) was not there at all.

Hello. In my vacuum cleaner this potentiometer also needs to be replaced and I am looking for one too. Please share information if you can find it. Best regards.

cocobongo · Answer

I desoldered and cleaned the paths of the potentiometer with spray for electrical contacts. After mounting the engine runs but only in the MAX position and at full speed. In any other regulator the engine switches off. Let me remind you that before desoldering, the engine worked immediately to the maximum and turning the pot did nothing. Now at least turns on / off ... After desoldering I saw on the 20K housing. The meter shows on contacts 1-3 from zero to 20 K, on contacts 2-3 from 20 K to zero (or vice versa). And it looks quite smooth. And how should it be? Can further cleaning of the slider's paths (yes, after bending the plates and getting inside the sweat) restore the proper functioning of the regulator?

gumisie · Answer

And what else, maybe WD-40 ?. As it is already: Contact PR and it is not known if it will work in this case.

cocobongo · Answer

MA Contact Cleaner. Added after 7 [minutes]: Another issue is the form of response. Or maybe WD40? It sounds a bit dismissive even if I used WD40. And we are here to help each other, not to point out weaknesses. Where is it said that only electronic graduates speak on the forum? Or maybe instead of trips about WD40 or other chemicals, some specific tip, link, address, for example, where such a pot can be bought new, or are all PCBs available for this model somewhere. Happy New Year!

I called Electrolux Polska internal 2 (parts). I gave the PNC number from the rating sticker and asked about the PCB for this model. I was sent back with catalog number 2193995533 to the site klinikaagd.pl. Lookup found this disc (commercial number KL691AA89) but it is out of stock and attempts to add it to the shopping cart were denied. Price PLN 100.90. I left an address asking for info when it is available. But for now ... there is none. I will be grateful for the indication whether you can and where to buy the 20K potentiometer alone (blue cube on the photo), because one hundred for such a piece of plastic (admittedly on the plate) is a bit overkill. Through the forum or at coco(_at_)boy.pl Or maybe someone has a different idea to turn on the switch with the regulator and make it work as predicted by the manufacturer ...? Contact as above. Added after 5 [minutes]: Oh. After folding the regulator (again) does not turn on / off the engine, not to mention speed control ... The engine spins to the maximum, turning the knob gives nothing. This can only be turned off by disconnecting the cable from the 230 V network. But a vacuum cleaner! Story! Like new art, it is not rushed! Added after 14 [minutes]: Thanks for the link. I should have it somewhere in the basement. For now, I used what first appeared, i.e. the Contact Cleaner mentioned earlier. But I will search and try it because I see it is dedicated to potentiometers. Added after 4 [hours] 53 [minutes]: As an expert, but certainly not in the field of electronics, let me ask colleagues more oriented question. What will put a 20K potentiometer in the place of a pot with a lower resistance, e.g. 1 K or the other way - a larger 100 K? I found such mounting potentiometers, one-turn, lying, but unfortunately no 20 K. Hence my question. While prices for a tile with this pot start from PLN 100 up, while buying the minimum required quantity (5 pcs) I will pay with delivery of about PLN 15. And there will be four more to give or withdraw as a gift to colleagues interested here from the elektroda.pl forum. Only for reimbursement of the shipping cost, unless picked up in Warsaw.

zulusj23 · Answer

Will you be buying from the Chinese? It seems to me that PT15 can fit and in this model they are worth 20k.

cocobongo · Answer

No. I found a shop / warehouse in Poland. Seems ok Added after 2 [minutes]:

janstan1 · Answer

In the attachment pdf I tried to present my case. That is, repairing the potentiometer, and thoroughly washing and adjustment. The condition before the repair was such that at first the vacuum cleaner stopped revolutions and then fell silent on amen. The recipe is taken from the cited Czech page - uC is MC9S08QD4 / 8-bit datasheet on the net / ...

Hello, Here is a link to the whole regulator for 32,90 + shipping 9,99: Greetings .

sergeyshevtsov25 · Answer

look for CA14NV15-20KA2020CFFCG

maras77 · Answer

I had a similar problem and generally repair without initialising this controller may not be successful for the reason that the controller is unprogrammed. . So perform the following operations (from the post First, with the hoover housing removed, set the minimum potentiometer value, i.e. short circuit to ground, plug the hoover into the socket - it will turn on at full power, turn the potentiometer to maximum and turn the hoover off - the whole action takes 3-5 seconds. In this way the board is reset. Once reset, set it on the hoover off, immediately after the reset. Now put the housing in the knob position at max, the potentiometer is at max (the maximum deviation of the potentiometer is also the maximum power of the hoover), insert the knob and pull it to the minimum corresponding to the hoover scale (neither more nor less - just the minimum). And now we start the hoover. Once the hoover is running and the electronics (softstart etc.) are initialised, everything works as it should. If not, the electronics have to be reset again or there is still a fault. In addition, this is also described on north.co.uk
