    Trouble with Minimax NT

    First of all Hello to!
    I have a minimax nt that is about 6-7 years old. I have recently started noticing that the heater will show a hotter temp on the display (about 25* higher than water temp) and it will not let the water get any hotter. If I raise the temp on the heater itself, say to the max of 104* it will heat till it believes it is at that temp. For instance again today, the water temp is 77* and when I looked at the heater it said 100*. No error codes given and appears to be functioning fine. Is there a calibration that I'm missing or has something let go?

    Thanks in advance,

    No there is not a calibration. Sounds like the temp control board is going bad.

    A word of caution: When working with gas and electrical you might want to consider a licensed contractor. Consider the value of your life and others around you.
