SkyMan 23,700 Posted August 6, 2020 Share Posted August 6, 2020 Is there a reason a ref would appear to be a short circuit? A coffee pot, iron, or other heating element would test as a short circuit but would a ref ever? I am trying to locate an electricity leak and when I put my Fluke meter on the plug of my caretaker's ref which isn't that old, not plugged into power, it reads 0 ohms. Is that possibly normal?

mikecon3 319 Posted August 6, 2020 Share Posted August 6, 2020 Just checked mine...on my Maytag, between line and neutral, reads in the megohms. On my Samsung, reads 4 ohms. So yes, I guess it is possible. We sure are going to miss Woolf, he would have an answer! 1 Link to post Share on other sites

New ref - no connection, old ref, short. Edited August 6, 2020 by SkyMan 1 Link to post Share on other sites
Daddle 171 Posted August 7, 2020 Share Posted August 7, 2020 The meter measures DC resistance. It is entirely possible that the AC will not "see" the DC short circuit but rather the reactance of an inductive device such as a motor. In other words, your measurement doesn't indicate much without knowing more about the device. It also depends if the thermostat control is commanding ON or OFF. The DC resistance and AC "resistance" in things such as simple heaters and old-fashioned lightbulbs is nearly equal. 3 1 Link to post Share on other sites
