Whirlpool front pcb parts

[Fintaneduffy]

1stly,great info on this forum, i have succesfully repaired my back pcb using the kit sold from here,

Model of fridge is FRBB2VAF20/0 (858640315000)
But i am struggling to find these parts for the front pcb, 3 capacitors

All that is written on them is
250v 1.70 MKP .68/10

I am unable to post a picture of this for some reason, but they are 3 capacitors all next to each other.

There is another site i found who someone posted pics of the components

Any help i would be grateful.

from what i can read they are 0.68uF (680nF) capacitors rated for voltage 250v AC

Yea but there are so many types to choose from, dont want getting the wrong type capacitor or does it matter?

[electrofix]

any x2 rated capacitor should be fine

Thanks for your reply mate, but i am a bit wary of the use of the word “should be fine” leaves me a bit hesitant to order just any x type capacitor

I dont wish to replace these with incorrect items.
The ones on that site seem very small compared to what is on the board.

More wondering has anyone succesfully found these components or something close, any links for these parts posted in other threads, links are all dead now so i cant find anything close.

x2 type capacitors are used as suprression capacitors which means they are connected to live and neutral all the time an appliance is switched on. If they were in any way not able to take the voltage they would be a dead short across live and neutal and there would be quite a bang

in your situation its difficult to know what they are doing without a circuit but the only other important factor is the value which in your case is 0.68 uF

as for the words “should be fine” it all boils down to i see no reason why it should not be successful but can never guarentee 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}. suffice ti say i would have no hesitation in trying it

ignor the size of the capacitors as new caps are smaller than older one as new techniques are used. the important thing is the tech specs

Ok that makes sense,
It would save cost of new board as they are so dear,
Il order some replacement parts of similar type like you said,

And if anyone has succesfully replaced them, feel free to let me knkw aswell, cost of the parts are nothing compared to a board.
Thanks again and if i succeed, il post up the results.

[electrofix]

is there any reason you think these may be causing your fault

it is possible in some circuit boards these caps are used a a power supply. just did one today on a Zanussi freezer where they use a single x2 type 0.47uF cap as a power supply to the board

On a few other threads here, they seemed to say it was these components that failed.
I am getting flickering lights when i adjust the temp, or operate the ice/water.

I did actually desolder them and measured them.
The 3 showed different values from 0.3uf to 0.1uf which is not what they should be reading i guess.
Im guessing they should be showing closer to 0.68uf give or take the 10{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} tolerance, so i am only guessing these are the problem parts

[electrofix]

makes sense they will be used as a power supply to the board. Capacitors act like a resistor on ac circuits ( look up capacitive reactance) the resitance goes down as capacitance goes up.

a 0.68 uf cap acts like a 4681 ohm resistor on a 50Hz supply

Dave

Yea this os the replacement part.
At 150 quid, if its possible id much rather spend a 5er replacing the dodgy components, when i am fit to do it
