The igniter comes up but no flame.
Answer Hello Pat,
The ignitor has to pull from 3.2 to 3.6 amps of current before the gas valve will open. In a nutshell, if the current is not high enough, the ignitor can glow red or orange without pulling enough current. The ignitor has to glow bright yellow to white hot before the gas valve will open. If you have a way to test the current, this will tell you for sure. If it is pulling sufficient current, the gas valve and/or the burner is in question.
My dryer will not light. Is this the igniter or a flame sensor. Gas valve will not open.
Answer Hello Ron. You will need to test the thermostats and the flame sensor and make sure they are good. They should read closed for continuity. Also, check the igniter to see if it is good. If it is not glowing, test for power. Here is a link on how to use a multi-meter for the testing procedures. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
