Solved Err: MAXTEMP BED

I keep getting a Err: MAXTEMP BED. When i check the pin on T1 for the bed it seems like the black wire melted. I turned on the bed once more when i had the bottom open then T1 black wire started smoking a little. I think the problem may lie in the beds thermostat. Should i get a hotbed ? or is there a bed therm i can replace the old one with ? I have the Robo 3 R1 bed with grey cabling Am printing with PLA with the bed set at 65 degrees
