Help, my beloved 20 year old Weller EC2002A Soldering Station has cr@pped
out! Although it seems to heat up normally and can even be adjusted, the
display only flashes "Err" briefly when turned on. I checked the
thermistor in the iron and it seems to be OK. I even bought a used newer
but junky looking EC2002-0 controller, but it seems to have other
problems and has different parts inside so a swap is not in order.

How does one fix these?
TIA

Joe -

Likely the problem is with the sensor/SCR circuitry on the control board
within the EC2002A base unit. 3 choices for repair:

1. You perform component level repair/troubleshooting on control board.
Since it has worked for 20 years, it sounds like one of the ICs (display)
may have failed. Weller tech support/repair (North Carolina) may be able to
help with part numbers.

2. Send unit to Weller for repair

3. Swap out (change out) the EC2002A control board.

Bob Wurth (eBay ID: bjwurth6969) has been selling NOS Weller control boards
for the EC series from time to time at reasonable prices (he had a Weller
EC1002 control board with no bidders last week).
