Bed not heating , control board issue
Bed isn't heating anymore , kept examining each part till I came to the issue as the board isn't sending any voltage to the bed heating port .
When I switched bed heater with nozzle heater , It worked perfectly
And when I measured voltage from the back of the board "Red circle in second photo " It read 0.14 V instead of 12 V .
does that mean I need to change the board or there might be a solution for that issue ?

Have you ever checked the fuses?
Maybe I would also check the bed thermistor.
Are the plug connections and all wires okay - no corrosion?

Checked the fuses , they are good .
The connections are also working as when I plug the bed heater in the nozzle heater port , it heats properly .
RE: Bed not heating , control board issue
Have you checked voltage between Heater + and incomming power - ?
the Fuse is in the +ve part of the circuit, And
the Mosfet is in the -ve part of the circuit

@noha-hani
Probably I have the same problem with the bed heating
middle of the print the bed heating stopped.
Cables and thermister are ok, no volage on the clamps on the board
Could you repair the board or is it necessary to buy a new one.
If you coud repair it please let me know how you fix it.
Thankx in advance.
