Question about Dryers
Infinite ohms means that the part will not allow electritity to go through it. Another word for this is "open". An ohm meter can tell you if a part is good or bad while the machine is unplugged. It's a very handy tool if you're going to repair your own machine. It is not necessary to spend a lot. I've seen them for as low as $2.89 at Harbor Freight Tools.
To test a part, use an ohm meter on the terminals of the part. You'll need to disconnect one wire from the part (to avoid misleading readings) while making the test. Be sure to replace the wires after each test. Nearly all the parts will measure less than one ohm. The heating element should be about 8 or 10 ohms. A failed part will measure "open" (i.e. the reading you get when the meter leads aren't touching anything.)
It may help to pull out the tech sheet, usually under the console. It shows the path for current from L1 to N through the heating element. You will need to test only those parts in this path.
I recommend checking the thermal fuse first. Its location depends on which dryer you have, but it's always near the blower wheel. If you need more help, I'll need to know your dryer's brand and model number (almost always inside the door.)
