MK3 Heated Bed is not longer heating

I have a new MK3. Have been printing on it for weeks with no issue. All of a sudden my heated bed doesn't heat up. It will not preheat. Any ideas what happened??

Check your thermistor cable under the heat bed. If it's intact, check to see that it's still seated in the Einsy.

Remove the cables cover and check if the cables are connected to the heat bed.

Are you sure the bed isn't heating up (hand on the bed, not getting warm?) Thermistor is the prime candidate, if it's getting warm but not registering.

Next, unscrew the PSU wires from the and check the resistance between those wires. If it is ~3ohm, your bed and wires are connected. If it is much greater than that (1000ohm to infinite), the wires have come lose from the bed or the bed is defective in some way.

Next, turn on the PSU and make sure that the middle two power wires on the bottom of the einsy have 24V between them. The middle two +/- DC power terminals are the bed suppluy, the left two +/- power are for everything else.

What are your printer temperatures? It is shown in the menu support->temperatures.
