The most difficult part of this repair was to diagnose it correctly. The dryer will run but will heat up for five minutes and then shut off and continue just on air drying. It will reset itself if you shut it down and restarted it again, to do just the same for another five minutes. All troubleshooting guides will tell you to replace limits, thermostat, flame sensor but nothing will tell you that the gas valve is shutting down.I found the problem after I bypass all limits to make sure that they were not dropping out and by process of elimination I came up with the gas valve.
The process to replace gas valve is as follows:
(A) Shut off incoming gas to dryer.
(B) Remove flexible connector from dryer located in the back of it.
(C) Remove all gas fittings attached to the pipe kit after removal of flex connector.
(D)Now place yourself in front of the drier and snap just the front of the top cover upwards without removing it.
(E) Place something in between the cover and the dryer drum just to keep the cover open.
(F)Disconnect the three wires of the door switch.
(G)Remove two 5/16" self tapping screws located in the top front (left and right) of the inside of the dryer.
(H) Pick up the front cover of the dryer and remove.
(I)With a phillips screw driver remove the three screws on the inside of the dryer that holds you air shoot and filter screen assembly.
(J)After the filter assembly is removed, clean all lint from blower wheel(now visible) and also from the filter assembly.
(K) Unplug all connectors to gas valve and also to the hot surface ignitor.
(L) Remove the flame sensor assembly with a 1/4" socket.
(M)With a 5/16" socket remove the burner assembly with extreme care not to damage the hot surface ignitor.
(N) Remove all three 5/16" screws that hold the gas valve and pipe kit.
(O) Remove complete gas valve and pipe assembly.
To install new gas valve assembly follow these instructions in reverse.
If you follow methodically all these instructions, you will have a successfull repair and remember at the end of this project your better half is going to know that you are a heroe.
