Still no heat, ignitor coil will not glow. Checked voltage on blue and red wires to ignition coil and reads 3.5VAC, red wire marked 3V and blue wire marked 1V. Any suggestions? Thanks, Dennis

Well i guess i spent about a hundred bucks to fix the dryer but i saved a thousand instead of buying a new one and learned a bit about dryers. Thanks again for your help Dennis
