My heat element is reading open, all the discussions here talk about shorted elements. Based on the schematic it looks like a working element should read 8-12 ohms. Is that correct? What would cause an element to fail open?
ANSWER Russ, Yes, you should have a resistance reading of 7 to 12 ohms resistance when you place your meter leads across the heater element terminals, with the wires disconnected. If you have no resistance reading(infinite resistance) then the element is "open" and won't heat. Of course there are several reasons why an element may fail, a weak spot in the resistance wire, a kink or sharp bend in the wire. will create a weak spot and after the electricity has flowed through the wire, the expansion and contraction process can cause the wire to separate, and stop heating. This can also occur "normally" based on usage, age, etc.
