My dryer will heat for a few minutes and then only blows cold air. We replaced the flame sensor, ignitor and now looking at the thermistor or coils. I am a little confused since some say you can test the coils for ohms and other post say there is no way to test them. Can it be okay for ohms and still cause the dryer to stop heating?
Based on my testing so far, the thermistor is the only element that does not have continuity.
ANSWER Hello Karen. You can test them, but it is not always accurate in testing the coils. Here is the test information. Check the coils and see if they test good. You can test the coils using a multi-meter TJMA-DM1. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Test the coils after running the dryer for about 10 minutes. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
