Joshua for Model Number wkgx201hba I have a brand new wkgx201hba LG washtower. Since we got it the dryer has not worked properly. We have Natural Gas. Sometimes it works flawlessly and other times the ignitor will glow red and just cycle on and off but never ignite a flame. Sometimes when it does this it will run the cycle till the end without codes, other times it will stop and throw a 9A5 code. Usually we can wash/dry one load and then it will be about 50/50 on the 2nd load. You can always forget a third load. LG has been useless in helping us. They keep sending contract techs that don't know the unit at all and have no clue. They wanted me to vent my gas dryer inside because they said it was bad ductwork causing the issue.... Our ductwork is all new and solid metal piping... They have made 4 trips out and replaced the main board and that did not fix it. Now they won't even respond to us so I am looking at taking matters into my own hands. Is there a way I can test this as I was under the impression it might be the gas valve, but as I said sometimes it works sometimes it does not. Thanks
Answer Joshua, the error code indicated is going to be the unit sensing the gas supply is either shut off, partially closed, or the supply hose is pinched. If checking the gas supply shows the hose is not pinched and the supply valve is fully turned on, the next step would be accessing the dryer main power board EBR31002606 and testing voltage output while it is in operation. At the connection BL3, there should be 90VDC from terminal 1 to terminal 2, and 102VDC from terminal 1 to terminal 3. If there is voltage but a flame does not ignite, the failure would likely be in the gas valve 5221EL2002A. The control can be accessed by removing the top panel of the dryer and it would be located on the left side of the appliance. Read More...
