    Pentair master temp 400- display blank

    Ok will do thanks! Any suggestions on where to purchase? I called my local store they want $800 for it. Online looks much less expensive, is it ok to purchase on Amazon if labeled pentair?

    It’s about 3-4 years old, as I live in FL I use it maybe 5-10 times per year. Ok so I need to replace the board. What’s the process for that?

    Hey guys, It’s my daughter’s 16 birthday and trying to heat the pool for a party. The heater is turning on, water feels warm but I have no display to check water temperature or heat temperature. I replaced the thermostat, no luck. Any suggestions I can do on my own?
