If the temperature reading was NOT the reason for changing the controller, there's a good chance that 135c is the maximum reading. This could indicate the sensor connection is open. Or, the controller is bad.

So, recheck all the connections. if that doesn't help, swap back the other controller to see if the temp problem goes away. If it's still there with the old controller, then maybe the sensor itself went bad, coincidentally.

Good luck.
