It is an EC2002A from way back. A nice clean unit except for the display
problem. I dug into it this weekend hoping it was just a bad capacitor
in the PS. It did start to work for a short time. There are numerous
potentiometers in the thing, its possible one is intermittent.

Subject: Intersil CA3162E/CA3161E A/D BCD/7Segment problem Weller
Soldering Station

Hi
I am trying to fil my Weller soldering station which has lost its
temperature readout. This particular model has the Intersil
CA3162E/CA3161E A/D and BCD/7Segment chips. When first turned on the
display flashes "EEE" and then goes blank. I shotgunned the repair by
replacing the filter caps in the power supply and though I had it fixed
but it is back to same problem.

In reading the Intersil application notes for the A/D convertor I don't
see a logical mode where EEE would be displayed

Does anyone have advice for troubleshooting this configuration?

Joe -

Which model are you trying to repair? EC 2002M ?

Positive your handpiece is okay? (Type-K thermocouple can go bad)

Bob Wurth just happens to have replacement control board
on eBay -- item number: 270057328135

reasonable price
