Before you start to check the heating element of either unit, start with checking the circuit breaker box located either inside or outside your home. A multimeter is a versatile tool that can be used to measure electrical resistance within a circuit, just as you would use a ruler to measure distance. Steps to test the heating element: You will be running a continuity test to see if electricity sent into one end of the element comes out properly at the other end. You can use an analog multimeter, but we suggest using a digital multimeter. Set the dial on your multimeter at the lowest ohms of resistance (ohms will have this symbol on it: Ω). This is why slow heating of water both day and night with a low wattage battery powered heater works out … Once you have your heating element taken out of your appliance, you’re ready to test it (both ovens and water heater are similar in steps below). 240V Spas.
