    Mammoth water source heat pump faulty thermistor.

    I need information on a kind of thermistor NTC or PTC and its working resistance. Heat pump model # MSR016MGC21-BL, with Mitsubishi electric compressor model #RS233VRDC in it. Sensor attached to water cooled tube in tube condenser. Firstly I tryed get any help from our Mammoth service division but 3 weeks passed and yet no reply. Secondly tryed to fix thermistor with a hammer. Once I have cured this way Daikin air sensor. Alas not this time. So gentlemen any info including wiring diagram would be highly appreciated!

    Found an old York fancoil sensor in my garage. Got it to replace faulty one in Mammoth heat pump. Have noticed the label attached to the faulty thermistor wire there.Name:  DSC00601.jpg
