Hello. My name is ***** ***** I'll be helping you with your appliance question today. Please wait a few moments while I review your question.

First, make sure your vent is cleaned and the best way to do that is just run a cycle without the vent hose connected to the back of the dryer to see if things change. If your dryer still won't dry properly, then this is a pretty common issue unfortunately and it means that your gas coils are starting to fatigue and need to be ordered and replaced. As the coils heat up, the unit stops opening the valve or can't hold it open as long as intended because it gets weak after it lights the first time. You just need to order and replace the 2 black cylinder gas coils located directly in front of the igniter. Below is a link to the part you'll need to order and replace.

The gas valves and igniter have been replaced. No change. Lights initially, goes out and will not glow on second attempt.

If you're certain the igniter won't glow a second time, then you have a bad thermostat that isn't resetting. You'll need to test voltage between the 2 posts where the wires connect on each thermostat when the dryer is running and not heating but it should be heating. Most likely your cycling thermostat is the faulty one, but you need to test voltage to be sure which thermostat is bad. Whatever thermostat you have 110 volts across from one terminal to the other, is the one you need to replace.

Thermostats are testing good when running and not heating. The length of time it will heat on startup seems to be getting shorter each time. This last time it was only lit for about 30 seconds.

What you're saying is not possible. I think it's time you call a technician out there because either one of the thermostats is bad or your coils are bad.

That certainly wasn't worth the money Doc!

You can go over the tests again that I gave you before, but you're over looking something that I told you to check or you're not understanding the tests I said to do because those are the only things that will cause your problem and if you say all of them check good the unit would be working.

Hello again. I'm just following up because I haven't heard back from you and I see this question is still open and unrated. Is there anything else I can help you with?
