Whirlpool Duet Sport wgd8300sw0 - drying time takes forever

Hello:
I am having an issue with the heat of my dryer. It takes multiple cycles to dry. I took the dryer apart and cleaned everything in duct and there is not a single piece of lint in the dryer now. Cleaned the blower wheel, all ducts, vents etc. and then tested all of the following:

  • coils: both tested fine at room temp (2-prong coil read 1,000-1,300 ohms. The 3-prong coil will read 1,300-1,400 ohms across prongs 1 and 2, and 500-600 ohms across prongs 1 and 3)
  • thermal fuse has continuity
  • ignitor has continuity and good ohm test
  • therm. cut off and hi-limit - both have continuity
  • therm. - internal bias (no continuity since high Ohm but am getting 11-12kOhms at room temp -66 degrees)
  • radiant flame sensor- has continuity

Tested the flame now - at start, ignitor glows, gas comes on. After that, the ignitor will just glow each time but no flame..
So after all that,
Could the coils still be bad even if they test fine at room temp? The ohms are good at room temp but no continuity. Should there be continuity on the coil at room temp or no at this Ohm rating? And can they fail when warm? Is there a way to test that? Would I need to remove when warm and is there a rating for them when hot?

Thanks!

Hi,

Yes they can.
A copy:

The coils on the gas valve are very bad for working once or twice and then quitting. If you find a open circuit on one of the gas coils, replace them all = less problems later on.

That is the time that one of the coils probably has opened up and testing them then is the best idea.

MattyP4321, thank you for your question. When the igniter is glowing for the second time, does it just continue to glow without cutting off, or does it cut off for about 60 seconds before trying to turn back on?
