**Note: If your unit currently has no thermistor connected and is being used, understand that this is not optimal for your unit and one should use the hot water sparingly to not cause further damage to the heating elements or other parts in the unit. Once your new set arrives, you can replace the thermistors and use your unit as needed.  

Also, If your unit has a black and red thermistor (newer model) please make a note for these as well and the proper set will be shipped out immediately.
