Why my ITC-306T won't turn off at set point

I have a Ink Bird ITC-306T temperature controller and I set my control set point to 99.0 and when I checked on it the temperature was up to 150.0 which killed my eggs in my incubator. I pulled the heat source away from the probe which lowered the temp but it’s still sitting at 103.0. I have a 2 degree differential. I also cleaned off the probe. Do I need to get a new controller?

Do you mean when the temperature reached TS (99.0), the work indicator of ITC-306T is off, but the heating outlets still on? Or is the probe reading incorrectly?
Could you please let me know the voltage and watt of the heater?
