Help Identifying a component via image (looks like a varistor)
That is probably a type of a thermistor (NTC or PTC).
Their resistance changes with temperature. 22K would be the resistance at room temperature (25°C).
Perhaps more info about the device would help with identifying the part, but I would suggest you trying to warm up / cool down the part and measure its resistance with your multimeter.
If it changes significantly, then it is probably a thermistor.
There are usually two types of thermistors: Negative and Positive temperature coefficient.
NTC thermistor's resistance lowers with higher temperature, PTC vise versa.
