David Jerde for Model Number WGD9400ST0 Our dryer doesn't seem to be heating, either in sensor mode or when running in timed mode. What troubleshooting can I do to identify the specific problem? There have been no changes to power availability and natural gas delivery, so I assume there is something internal preventing the heater from firing.
Answer David, You will want to check the thermostats and thermal fuse to make sure that they are good. Check the igniter to make sure that the igniter is glowing when the unit is turned on. If the igniter is turning on then check the flame sensor and if this checks ok then the issue will most likely be the coils on the unit being faulty. If the igniter does not glow then this would be more likely that the igniter is faulty. Read More... Answered by AppliancePartsPros.com | Tuesday, October 11, 2016
Answer David, The first check should be at the dryer exhaust pipes and vent hood. They can get restricted with lint, get kinked, twisted and this will reduce the air flow and cause the dryer to take longer to dry. You can disconnect the venting from the back of the dryer and run a "normal" sized load, it should take 30 to 40 minutes to dry the load. If the problem persists, remove the lower access panel, start the dryer and observe the gas burner. the igniter should glow, then start to fade and the burner flame should ignite and burn. it should cycle like this for the complete cycle. let the dryer run and heat for 15 to 20 minutes, then re check the cycling process. If the igniter glows and fades, but there is no flame ignition, you most likely have defective gas valve coils, and they will need to be replaced. Read More...
