Re: Kada 852d+ need schematic

but why it worked after desoldering ic? maybe just another heat to make some component work normal

Re: Kada 852d+ need schematic

So i think i have broken controller of temp. I try to hook up my iron from another station and it wont turn off on temp like the hotair.

looks like everything is controlled by that long IC in socket, but it is absolutely nothing marked on it

count the pins and see where they go - or atleast the power goes on it.

loos like it have voltage from that 5V regulator LMxxxx

Voltage looks everyvhere ok on its pins.

i was thinking that compressor looks after sensor to cool and shut off, but after power off it cools heater right one minute before turn off, so it is not controlled by it

so sensor driven controller circuit not work

Re: Kada 852d+ need schematic

I have a KADA 852D+.
Have not torn apart into it in years... but let me know if you still need any info, like where wires connect and whatnot.

Mine was a 230/240V version that was re-wired as a 120V version by simply changing the plug by whoever sold it to me. Luckily, I found another transformer from a similar dead station and wired the two transformer outputs in series to get the proper voltages.

Someone has a connection to the cables, I burned a resistance, I don't know what value it is
