How do I test my pool spa heater?

You test the element by using an Ohm meter, or any multi-meter will work also. Just place it on Ohms, at 1000, and place your test leads on each of the terminals (power to spa heater should be off). As mentioned above, a measurement of 9-12 Ohms of resistance usually indicates a good element.

What to do if your swimming pool heater is not working?

Make sure that the pilot is lit (millivolt heaters). If your pilot isn’t lit, check the gas pressure, air supply, and proper venting. Make sure the pilot tube is intact and not clogged. For MV heaters, if the pilot won’t stay lit, check the output on the thermocouple. Is the gas supply valve in the ON position?

Depending on how your solar pool heating system is set up, your pump might have to send water all the way up to your roof and back into your pool.

Why do I need a pressure switch on my pool heater?

Close water features, or alternate them, until the pool heats to the desired temperature. The purpose of the pressure switch is to ensure that water is flowing through the unit before it allows the heater to turn on. The pool pump must be ON and your filter clean for the switch to close and allow voltage to pass through.

Why is my pool heater not turning on?

Solution: If your pool heat pump isn’t receiving the power it needs from the breaker, then it won’t power on at all. But if the heat pump was previously working and no longer turns on, a damaged electrical connection could be the problem.

That is to say we’ve had more warm, sunny, dry days than rain for a change! Summer means that for those who are lucky enough to own a spa pool, it will be getting much more use than normal.

What to do if your spa heater does not heat?

Once they are removed, tape them together; turn the thermostat dial down to the off position, and turn the power back on. Make sure the spa is on the heater/filter cycle and water is flowing from the jets, turn the thermostat dial up while watching the contactor, if it closes when doing this, then re-test the heater using the amp-meter.
