    Pentair MiniMax Spa Heater

    Out spa heater appears to work fine except it heats the spa to 104 and no matter what temperature we set it on, it simply goes to the high limit. I've tried changing the hi temp at the spa, but it still goes to the max. Also we control the spa via a remote panel in the house. Any ideas on what we need to do? Thanks.

    I don't know this specific heater, but most all use the same basic principals to control the temperature. I'd check for a stuck snap disc or a bad thermistor.
