Re: Makita 440 Cap types?
GUYS
You helped me a lot, so had to let you all know that after buying new carbon brushes, then a new circuit board, to fine out that it was the god darn switches
Its okay now, i inspected the old switches and they were contaminated inside with dirt, you wouldnt think a normal on/off switch would of been the fault!
oh dear
anyway guys thanks for all your help!!!!!!!!!!

Re: Makita 440 Cap types?
dam guys im GUTTED!!!!!!!!
Switched on today first time in 3 days and smoke out of switch area! i hate being defeated after many hours!
Might have to spend the £50 on the new board $75
As my soldering wasnt perfect and did i choose the wrong parts???
sad day for the makita 440Leave a comment:

Re: Makita 440 Cap types?
well well well Guys
I got me parts today 1-2 hours soldering 3 bits on
The Makita worked, Then i tried again didnt work and again didnt work again worked, again worked!
Im not sure if the switches are dodgy? what do you guys think?> or do caps and resistors need breaking in???
i will keep testing and let you know how it goes here are the 3 x new parts ive used!

will the new one above replace the STP16A60 Bi-Directional Triode Thyristor
Repetitive Peak Off-State Voltage : 600V

◆ High Commutation dv/dt

Re: Makita 440 Cap types?
HI
Think ive all 3 x new codes for parts i need now?
Is this correct guys?
thanks again...Leave a comment:

Re: Makita 440 Cap types?
Im so busy im building a new CNC Machine also, and a new board is £50
Also havent learnt yet how to do that, seen youtube videos but id be better replacing i think as at least then i know what bit were new etc
basically im new to soldering, and never tested a cap or resistor before, not yet
see the big yellow ones too big, not sure how i made that mistake...Leave a comment:

Re: Makita 440 Cap types?
I Spoke to soon
Got the new yellow caps and they too big
anyone know where i can get the other heatsink with 3808
and 10W0r047J and R18 3.9kLeave a comment:

Re: Makita 440 Cap types?
I cant find anything on google with those codes, is there any alternatives to what resistors i should buy?
Ive already ordered the yellow ones but wanted to try and get new[B] heatsink with 3808 [/B]
and [B]10W0r047J [/B]and [B]R18 3.9k[/B]

Re: Makita 440 Cap types?
BRILLIANT!!!!!!!!!!!! Thanks for all youe AWESOME TIPS And replys guys, BIG THANK YOU
That has been so so helpful each reply has been very very helpful, the yellow cap prone to blowing and what its for THANKS Kv8adu for that
i seen that yellow cap in a youtube video! Thanks R J for the code for the large resistor i already ordered the yellow caps and wil now order the R18 and 10w0r047j
Okay i will order in new resistors but not sure what those top ones are but i will try the long one and yellow one first...Leave a comment:

Re: Makita 440 Cap types?
Yes put brand new brushes in the last two looked okay also, thanks for the tip
Does anyone know the type of resistor and small caps at top??
thanks againLeave a comment:

Makita 440 Cap types?
Hi Guys
I have a[URL="https://www.toolstop.co.uk/makita-440-wet-dry-vacuum-extractor-240v-p3014"] Makita 440 Vacum[/URL] and when i was switching it on it wouldnt work but LEDS were on at switch
When i opened it up looked okay
The power is going to the switches okay, i tested the motor direct to 240v it is fine
So the only other bit is this[B][U] small PCB [/U][/B]and im a rookie and cant/wont pay £50 for a new board or $80
So was wanting to replace the capcitators, can anyone please let me know what the small... -
