WebStep 3. If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. Any reading above 1.25 is considered excellent. WebThe water heater element OHMS chart (left, courtesy A.O. Smith) describes the actual ohm reading you'd expect if testing a factory OEM heater element of the wattage shown. Even without that level of detail there is a …

So I suspect your heating element has some inductive quality you are not measuring with your meter or it was still connected in the circuit. Otherwise, your 30 amp dryer breaker would be tripping. Resistive elements don't normally drop in resistance. They usually open up. WebPhase C: The multimeter is set to the OHM setting. Phase D: Both leads on the heater element are tested. In case the multimeter shows a measurement of 9 to 14 OHMs, the element itself is not the issue. But, if the reading on the multimeter is 0 or “open”, the heating element is bad and not working properly. lake minnetonka public access
