For the disassembly of the machine, you can use the following document and the videos linked within it as your reference.

Insert 2 sewing needles into the 2 connector terminals as shown in image 1.
-
Connect one end of an alligator clip to each one of the sewing needles and connect the other end of the wire to the multimeter as shown in image 2.
-
Place some electrical tape in between the red and black alligator clips to electrically isolate them from each other as shown in image 3.

-
Apply heat to the thermistor/probe using a heat gun or a lighter. The probe resistance readings should gently decrease as the temperature increases. Since this one is damaged, it works unpredictably. Refer to the video for more clarification.

Youtube video that goes explaining each step, comparing the behavior of a malfunctioning probe with a normal one.

Excellent clear guide. I have a Philips Essential XL HD9280 Airfryer, will it also have a 200K Ohm NTC Thermistor. I guess they are fairly generic in terms of design.
I'd try with a 100K Ohm NTC thermistor instead of a 200K since they are more commonly used. Try measuring the resistance with a multimeter at room temperature to see if it is within the vicinity of 100K or 200K and buy an NTC thermistor with a similar value. Don't hesitate to ask if you have any questions.

Excelente guía clara. Tengo una Philips Essential XL HD9280 Airfryer, ¿tendrá también un termistor NTC de 200K Ohm. Supongo que son bastante genéricos en términos de diseño.
Todas las freidoras de aire son muy similares, casi seguro tiene uno similar o el mismo.

Yo probaría con un termistor NTC de 100K Ohm en lugar de uno de 200K ya que son los más utilizados. Prueba a medir la resistencia con un polímetro a temperatura ambiente para ver si está en el entorno de 100K o 200K y compra un termistor NTC con un valor similar. No dudes en preguntar si tienes alguna duda.
