Fantastic information! Direct and to-the-point video. Understanding how these systems work is so helpful while I'm trying to keep these appliances running. Thank you so much for your knowledge!
ok if I had to guess why two coils and why two valves. Probably the first valve is just a simple on-off, The one that is controlled by the coil that has two prongs only - open/close circuit. The second valve (the one that is controlled by the 3x pronged coil) can be half opened or full opened which would match the low heat and high heat settings on your dryer. So your dryer logic would close the circuit on the two coils to open first value fully (probably a security mechanism - that is after all a gas heater - u don't want one gas valve to fail and then it is gas in your house) and the other coil would open the second valve either at half or full depending on the heat setting (low/high respectively).
The flame on my dryer started blowing wildly, and so far I've ruled out the vents being dirty (I cleaned them anyways), and I'm thinking it has something to do with the valve. I took it apart as I was curious to how it all works. It's very similar to the one you have here in that it works that same way, but it's a different style valve for an LG. I found a build up of lint in the bottom of the 3rd spring, the one that's not in the piston area. I'm not sure if that's the issue- I still need to check the see if the coils are good or bad. Gas gets through the valve but the flame is wild and orange instead of steady and mostly blue like it should be.
Ini have a brand new maytag mdg20, it glow but no flame. The day before it was just fine. I think, the gas valve stuck. Still waiting for under waranty technical support to come and find out the problem.
Hi Scott I have a kemore Elite gas dryer, Hmy initial problem was a gas leak from the burner.I took the burner out ,opened it up cleaned it and that problem went away, Now, my thermal fuse situated right over the flame chamber keep getting blown and when I'm dring clothes my gas meter from the basement is making noise like rattling pipenoise. I'm wondering if it has to do withe the valve piston, whether I switched them places. I remember one of them was a bit longer. The other think I can think of is to vaccum the exhaust vent air flow. Please help
@spinny2593 21 minutes ago I have checked everything continuity good on all fuses and well everything. So I changed the coils. You are the only one that talks about the metal sleeve. The small one in the back does not have one and I can't tell anywhere if it should or not. I have done everything and it still will not heat. Get my glow and then click it shuts off and nothing.
@@ScottTheFixItGuyChannel Oh and I did pull the wires off first of everything. I'm just wondering... does this mean in your opinion that the gas valve is messed up?
I had a repair guy here. He replaced the coils but still not getting gas. What else goes wrong? The gas valve is no longer available but what's to fix?
@@ScottTheFixItGuyChannel If only it were so easy. I'm going down that path which means removing the washer finding a place to put it to get the dryer out to get at the line. But this thing has been working for 40 years. I said there was no gas trying to simplify but the tech told me there is just not enough to always ignite so partial combustion or no combustion causing gas smell at the exterior vent. His theory was the energized circuit was causing the circuit to not completing correctly so path to ground was not going where it should. I don't recall excatly how he put it. Tech put in newer coils so he had to rewire with different colored wires. I have no clue how it should be wired now because he had to pull wire caps. Hell maybe he wired it wrong and couldn't get it working even to what it was before. I heard hammering at one point. I was watching him for a while but he asked me to leave feeling nervous with me "watching over his shoulder".
Hi Scott, need your advice. I have a Kenmore Elite HE3 gas dryer and I recently found some minor to medium gas leak around the valve (using a Home-Flex detector bought at Home Depot). I'm wondering, instead of changing the whole assembly (the valve plus pipe is sold together), if there is anything I can fix on the valve, such as loosen parts, or maybe the coils? Thanks a lot.
The title of your video is How it Works but you don't explain how it works. Why are there two valve? When are each valve energized? What is the function of each valve? All you do is take it apart.

Thanks so much Michael 😊😊😊
Thank you sir!
This was very helpful and informative. It's hard to find actual info on what's inside of these.
Glad it was helpful!😊
Great video! I just replaced the coils yesterday and was interested in how they worked to open and close the valves. Thank you!!
I would just remove the big black hose that runs between the disposal and airgap and really clean it out👍
Well done. Thx for posting.

Great question,
I would buy a new valve.
It should come with the new coils. That will fix it for sure👍
are there metal inserts on both coils? what happens when the insert is missing?
Just on the big one. The insert might still be on the metal post👍
@@ScottTheFixItGuyChannel thank you

I would replace the gas valve. They’re really hard to repair.

Did the flame sensor have continuity?
@@ScottTheFixItGuyChannel Yes... That is why I am blown away. Figuratively of course. Everything has continuity that I could find to test.

I’d check where the gas line connects to the dryer to see if some of the thread compound is blocking the flow of gas.

Explain the flow of electricity by means of a wiring diagram. and the holding coil. The why and how current is flowing
FYI: After 27 years I had to replace the two solenoids, not bad for a dryer...
Very impressive 😊

I usually tighten the brass nut that connects the pipe to the valve. I believe it’s lefty tighty.
You can soap test it when you’re done.
Those pistons have different lengths.

I agree! Why are there two solenoids and two valves? Why does one solenoid have 2 leads and the other has 3 leads? Scott, please answer up!
