Heated Bed Temperature Jumpy: 28deg --> 60deg, back and forth

Hi,

any ideas would be appreciated. I didn't have much luck with my printer (didn't assemble it for a long time, after assembly, MMU1 keeps failing, never worked, now after maybe 6 months of  low usage the heated bed is giving issues. I built many MANY printers. 

Room temp (default heated bed temp value): 28degC

Heated bed temp (PLA): 60degC

What happens is the temp reading is intermittent, ie. 28degC, then 60degC, then 28degC, back to 60 degC, you get the idea.

Thermistor seems fine, wiring seems fine. Plugged wires in/out many times. 

What can I do next? Change main board? Change thermistor?
