There are two models (at least) of this oven. One has orange and blue/(white-ish) LED's and the other (earlier version) has only blue. [br]

The blue-only display has 2 wires. The blue/orange will have 3 wires.
I suggest ordering 10 since it will probably take a few tries to get them installed perfectly. I found hot-air rework was a bit too much for this 2mm wide PCB a super fine low-temp like for a Metcal station will work best. Test the PCB with 10 mA of current before returning to the display board to make sure you have it right.
I found you need to disassemble a LOT to get to it.. But, I found you will have the best luck if you remove the top cover with the control panel still attached to the top cover. (One screw underneath to allow it to be removed.) Obviously, other stuff needs disassembly - bottom feet, small metal spacer in feet thingy. There is a helpful YouTube video by a guy "Dave" on disassembling, but he's kinda brutish and gets impatient @ the end and just bends stuff. Totally unnecessary. He also prys up the cover to use an extended screwdriver to reach the front panel. Again, Not needed. Keep the CP attached until you remove the cover.. Then remove the CP and disassemble it. Keep screws sorted for different lengths and types.[br]
