How does the heater relay work in a spa?
When the spa’s thermostat detects cold water it allows electricity to energize the relay control-circuit’s electromagnet. The relay’s load circuit has constant voltage applied to its input terminal. When the control circuit energizes, its electromagnet closes an internal switch in the load circuit.
How can I Turn On my spa heater?
Turn the thermostat to the high-heat position. This should turn the spa on and send voltage to the heat relay’s control circuit. Place a voltmeter lead on the ground screw.
How can you tell if a heater relay is bad?
If one pin has voltage but the other does not, then replace the relay. Place a voltmeter lead on each load-circuit output pin. The voltage reading should equal the voltage reading at the input pins. If not, then replace the relay.
Where do I find the VAC on my spa heater?
Check the spa’s identification tag for the input voltage. The identification tag, located in the electrical service area, states the spa’s model number, serial number, input voltage (VAC) and the system’s amperage. Turn a voltmeter to VAC.
