<p>The resistance of Lead "A" heaters wired in parallel = 52.3 Ohms per set.</p>
<p>I measured the "B" Lead Ice management cartridge heater set. It measures 104.7 Ohms. </p>
<p>This would indicate one "good heater & one of the heaters is "OPEN" </p>
<p>I won't know which one until they are separated. </p>
<p>New replacement heaters are $59.70 ea. I suggest getting a couple of spares.</p>
