Jacuzzi J-300 displays the incorrect temperature...

[adorotik]

Help, my Jacuzzi J-300 is displaying the wrong temperature (says 100, is too hot to get in).  It's about 4 years old.  I lowered it to 93 and it feels about 102...

Is this a temperature sensor problem?  Replace?

 If it's only 4 years old, it should be under warranty, give your dealer a call.   But yes it sounds like the temp sensor, easy to replace if you want.  Part number is 6600-166
