After questioning about my broken thermostat there Debugging an old Thermostat: What component is this? (3 pins SMD IC), thanks to @JRE I could find that it was actually the relay on the board that was broken. Now I'm looking for a replacement of this relay, but I didn't think it could be so difficult to find it... I need either to have a correct naming of this component so that I can find it, or a website + specific component to buy would be so much better. I already checked mousers, digikey, rs etc but couldn't find a suitable replacement. The main reason is that I can't find one with the same pin out (I've got 3 input pins due to the dual coil, and also 3 output pins. The output pins are not aligned, also see picture below)
Here is the detail of the component (from my understanding, please also check the picture below): Dual Coil Latching Relay, 3Vcc 21 Ohm coil, 8A 250Vac contacts, SPST (not sure this is the actual acronym because it's dual coil).
- Update: What's wrong with the broken relay?
The relay "clicks" both ways (i.e. whatever coil I supply, the relay clicks), but only two of the three output poles are connected (i.e. one position doesn't work even if the relay clicks when it turns to that position).
