WM CGa control board

PDB2

Boiler wouldn't start any further than the first green indicator in startup sequence. Luckily I had invested a spare board some 14 years ago soon after installing boiler and it got me back up and heating. So now I'm looking at getting another spare to have on hand and finding the price has increased 3-4 fold over the years. Yikes….is there anyone that rebuilds these things or is it just to much of a liability ? Not that the unit has required much over the years other than an igniter maybe, but just curious mainly.

High failure items on control boards are, solder joints, relays and capacitors. If you (or a friend) can deal with those items it can be an inexpensive repair.

For most industrial electronic repair companies the hourly rate makes it not economical to repair circuit boards that can be (rather) inexpensively replaced.

There are places that seem more focused (and probably others out there)

That appear to do that type of work, I have never dealt with them.

IMO (I'm not a Lawyer, but have done a tiny bit of research) where the liability issue mostly comes in is when someone modifies the circuit board away from the manufactures original intent. Simply correctly repairing age related or use related defects, is not a big deal.

The pipe is leaking, the plumber replaced it.

The capacitor is defective the electronics tech replaced it.

Not the big drama some folks seem to want it to be.
