Were they working ever before this issue? Did the small tank valve have the internal shut off activated when you opened the valve to charge the line? Sometimes long hoses will allow a quick large volume of gas through and it trips the internal flow limiter. Do you smell gas at the appliance? Sometimes the valve only opens for a certain amount of time and tries igniting but if no heat sensed on the thermocouple it closes valve. You might just need to bleed line to get propane up to valve faster. Pictures could help.

They have never worked and are both brand new appliances hooked up to a brand new, full tank.
I didn't realize tanks had a flow limiter built in... may try slowly opening the valve to maybe bypass that.
I don't smell gas at the appliance, but when I disconnect the hose, there is gas and pressure in the line.
Is there a safe way you'd recommend bleeding the lines?
You could try loosening a fitting near the valve body and bleed It out. You could also get a lighter and hold it on the thermocouple to trick the valve into opening. Or there could be a bug stuck in one of the orifices.
I will attempt hopefully just one, but probably all of these things tomorrow. Thanks!
Any luck? The propane tanks work on other things like grill?
No dice. I'm going on 7 hours of back and forth, bleeding lines, checking connections, fiddling with stuff...
Yes, I even tried a third tank (pulled off my griddle) to try.
I got the dryer to get warm, but by the time I noticed it was warm, it had lost flame again.
For a while it would light briefly and die out.
I thought maybe it was the lack of regulator making it die out, so I swapped hoses for one with a regulator, and ever since then it's been back to square one: nothing.
Could have crud or bugs in the pilot gas tube. They seem to like to crawl into propane pipes. Maybe take a blow torch and clean off the thermocouple in case there is grease or carbon built up on it. Or clean thermocouple with paper. Make sure there isn't a draft blowing the flame away from the thermocouple .
I guess I'll have to give that a shot.
I don't have time to take everything apart again this weekend, so that'll have to be a next-weekend thing.
