    Hayward 400btu Heater starts and runs but not heating

    Hello, Opened pool up for the season yesterday and turned heater on today. It appears to light the blower is on and the flow is fine. It does not sound anywhere near as loud as it used to and the water returning back to the pool is at most 2ﾟ warmer. Any thoughts?
