 Dryer Heat Will not Stay on
Ok, it turns out mine is the gas valve. I removed the bottom front cover and I had clear view of the gas igniter assembly. I first cleaned all the lint with my vacuum, and then tuned the dryer on with out any laundry. I could here the solenoid click for the igniter turn on and see the glow rod got red hot. After a few seconds I could here another solenoid click and the gas ignited. Great, I thought. I started a timer and watched the gas cycle on and off for 20 minutes. So I decided to put some laundry into the dryer thinking that it might be a moisture sensor. I started the dryer again, and started my timer. I came back in 15 min to check the status of the dryer. To my disappointment, the gas was not burning. So, I started wiggling the wiring harness when the igniter was glowing thinking that there is lint or something causing a bad connection. Sure enough the gas solenoid clicked and the flame ignited. Hay, I thought, I found the problem. So I disconnected the power and disconnected and reconnected all the connections in the wiring harness and tried again. Well, it did not solve the problem. So, again, when the igniter was glowing, I wiggled the harness and the gas flame ignited. This time I noticed the solenoid that is closes to the front of the dryer moved. So, with the gas flame burning and the igniter off, I wiggled the wires connected to the solenoid. Sure enough, the gas flame shut off. So, I tried the same process again, and was able to repeat the starting gas flame and the gas flame shutting off. (the flame would turn off from the result of me moving the wire harness, not because of the normal cycle of turning off the flame) So, I went and got some epoxy glue and with the gas flame running, I glued the side of the solenoid to the metal base. The gas did its cycle, and sure enough the flame did not ignite. It took me a couple of times moving the solenoid until it made contact that would allow the gas flame to burn before the epoxy glue dried, so work fast before the glue dries. Once the glue was set, the dryer worked normally.
Now, I initial replaced the timer and that did not solve the problem. My thought was that the time mechanism was not turning the gas on to heat the dryer. But reading some of the forums, I learned that the timer only advances when the Cycling Thermostat cycles on and off. So, my 39.95 (Ebay) for timer, was spent because I did not do my due diligence to read these forums and learn from others. So, be patient. I am fortunate that I have two dryers; it takes twice as long to dry cloths that it takes to wash, so I was able to take my time with the troubleshooting after my initial investment. Now, off to the internet in search of a Gas Valve. (even though I have the dryer working, I want to replace the gas valve. I am sure that the vibration of the dryer causes the solenoids to shake loose from its self.) Thanks to all the post on these forums, my wife wanted to purchase a new dryer and the low end for a gas dryer is around $350) |
