ATX power on TEMP 2000

[Amilious]

Ok, I think i messed up bad. Is there anyway I can fix my board. I set up a relay and it was working well. However i used a different phone charger for the USB that supplies the 5v. It was the Samsung fast change one. It says on there i can supply 9.0V 1.67A, or 5.0V 20A, the one I was using before supplies 5.3V at 2A. The 5.3V one worked fine, not looking i plugged it into the other one and was working on setting up my Z motor sync. When doing that the therm on the hot-end bummed into my paper clip holding down the glass and tore the wires out of the therm. The thing is i get 2000 on both bed and hot-end. The web shows fault on both heater 1 and heater 2. I removed the 5v power supply and used only my normal 24V powersuppy and removed the 5V jumper. It starts up with the same issue. 2000 and 2000.

Error: Temperature reading fault on heater 0: sensor open circuit

Error: A heater fault has occured on this particular heater.

```I'm sorry for coming to the forum with so many issues. What did i break and what do i need to fix it. My rework kit should be here tomorrow.

you may have fried the analog sensors on the CPU

[Amilious]

I'm looking into the VSSA fuse. Eerything but the temps work.

[Amilious]

multimeter on ground and vssa is OL

ordering 507-1797-1-ND

[Amilious]

hmm so maybe the power supply is ok. It must have been the hot-end hitting bed clip. I found other post saying the same thing.

[dc42]

It's also possible to convert the board to use a self-resetting PTC fuse, see https://duet3d.com/wiki/Connector_and_spare_part_numbers#VSSA_fuse.

[Amilious]

Thank you, 507-1797-1-ND is a 0ZCJ0020FF2E, so that is the plan.

Ok I replaced the one for tr1 and tr9 tested and working. But i lost one of the pads when removing the tr5(the first one i did). The pad i lost was the pin2 or the source. Where can i connect it too. Please save me. Oh, i also removed the vssa fuse, my auto resetting one should arive tomorrow. It i put it where the original on was, can i stil connect the resistor on the back.

when lifting the old mosfet the pad came with

[dc42]

The source pins of the mosfets are all connected to ground. So you can connect the source pin of that mosfet to the source pin of one of the other MOSFETs. Or you may be able to connect it to the ground via that the pad was originally connected to.

The new VSSA fuse is larger than the old one so it doesn't fit in the same place.

Thank you for all the help. I appreciate the level of support you provide. I will do my best to contribute back to the form when I can.
