Whirlpool gas dryer presure regulator leak limiter vent cap color

[grizzly]

Yesterday I acquired a used Whirlpool gas dryer (model: LGR8858EQ3) for my continuing appliance repair home self study program. I noticed that the cap on the leak limiter is painted blue. Does this mean that it has been converted to run on LP?

If so, is there a way to order just the cap to convert it back to natural gas?

Finally, do you just use regular TFE pipe thread paste when installing this cap?

Thanks!

I figured out the answer to the previous question, but now I have a new one. Turns out, the part I thought was the cap on pressure the leak limiter wasn't really what I thought it was. I figured out that the leak limiter cap is actually the brass cap with a flat blade screw driver slot in it. And mine has NOT been converted to LP, it is just a cap, with no rod in it. But the question now becomes, what is the silver cap with blue paint on it called, and what is it used for?

It is called a pipe plug (1/8" NPT). I am not sure why you'd ever want to remove the plug, probably has to be there as part of the mfg process. I always use the pipe thread sealant "real-tuff" by Hercules but you can use any pipe thread sealant or even tape if you like.

Thanks AccApp!

The reason I had it off is cuz at first I thought it was the leak limiter cap. But, as soon as I got it off and shined a flashlifght in the hole, I didn't see an adjustement screw in there like the Whirlpool manual shows. Right about then, I realized the brass cap on the other side was acutally the leak limiter cap. So I took the brass screw off, and sure enough there was an adjustement screw in there that you you can adjust the pressure diaphram with. The stuff on the threads is orangish and looks like that heavy duty thread lock stuff that is usually blue that you see on a lot of automotive applications. I ended up just reusing the orange stuff that was already on it and it sealed up REAL tight.

I bought this old machine yesterday to advance my self studies into the realm of gas dryers. Never had actually used one before and just wanted to figure out how the igniter, burner, coils, heat detector and all those fancy doo-dads work together.

The reason it is there is to be used as a pressure tap to check your gas pressure after the regulator.
