- Check Connectors
The connectors from the print bed to the motherboard may have melted or may be charred. If this is the case, your printer may have smoked or started to smell before your print bed stopped heating. To check the connectors, open the electronics case and see if the connectors for the heated bed are melted or charred black. If so, your motherboard will need to be replaced.
- Check Wiring
To check the wiring, open the electronics case and make sure the wires for the print bed are plugged in and undamaged. If they are, check the resistance on these wires. If the wires are damaged or cut, they will need to be replaced.
- Check Voltage
To check the voltage to the print bed, open the electronics case and preheat the print bed. Use a volt meter to ensure that the bed is getting 12V. If it is, then either the wiring or the bed itself is faulty and will need to be replaced. If the bed is not getting 12V, then the motherboard is faulty and will need to be replaced.
