Based on your advice I have purchased new thermistor AP4113421. It reads 68k ohms at room temperature and 28K ohms when water is hot. Which is about the same as my old thermistor. Needless to say that new thermistor didn't fix my original problem. In your reply to Bob you mentioned that it should read about 10K ohms at room temperature. Did I receive defective part or your answer to Bob was incorrect?
ANSWER Hello Slava. According to the manufacture. The Thermistor 99002565 should read 10K ohms at 77° and 2.4K at 140°. It sounds like the meter is not set correctly, or is reading the parts incorrectly. If the heater is good, and the thermal cut-off and thermistor are good, and the heating is the problem, you may have a bad control board 99002824 in the unit. Hope this helps.
