Before when I started the 3d printer, the same temperature was displayed as the room temperature, but now it shows about 15 degrees higher than the room temperature. I have not changed the configuration file. The displayed temperature increases.

Have you checked your wiring and / or replaced the thermistor? Maybe a cabling issue or a dead thermistor.
Hi Sineos.
I disconnected the thermistors and reconnected them again, and now it is showing the right temperature. I have no idea why it showed the faulty temperature before.
I am glad its working now, and I hope it continues to work 
Thanks for your help Sineos.
