This is the second time that this sentronic has burnt up. Looks like the L and M terminals are burnt on the board, but maybe a little larger area than that. When I installed the last one I checked the ops and it failed properly, and reset properly. About a month later it burnt up. Cant even push the reset in. Any ideas? Thanks in advance.

Oh, its 230 volt four wire. Jumper has been removed.

Somewhere along the wires there is an extra load, if not, just try another make, like Dafoss or Ranco.

What is it? Sentronic in google comes up with dozens of unrelated content.
