I haven't used a propane burner much, but I use a propane torch at work. I just torch the tank now and then and pressure is back.
The tank will freeze over easy when it's cool outside and I'm using it at maximum--and that's a 9 gal. tank.

It was probably just overfilled, no need to worry. It will be fine once the level goes down. Propane is cold after all.

Propane is ambient temp. The pressure change when releasing it will drop it's temp.

If it makes a difference it was probably around 48º - 50º when I had it filled and closer to 58º-60º when I was starting to use it.

Didn't they add the newer valves with a float to prevent overfilling the bottles a couple years ago?
A new 20# valve/float will only hold 4 plus not a full 5 gallons propane.
Charge the same price filling a 20# with less propane means more dollar refill profits.

If you have the proper fittings inverting the larger overfilled bottle and drain off a gallon or more into the smaller bottle that is in its normal position. Tank to tank fittings with the proper short hose will do. Open the vent valve on the smaller bottle being filled.
This way you'll have gas flow thru the regulator instead of liquid from the larger bottle preventing freezing of the regulator.
If your pulling a high volume of gas feeding many large burners at once the regulator may still freeze up even under a gas discharge condition depending on the air temps your working at.

I have to assume this tank is at least 10 - 15 years old.

The age of the tank does not matter unless you still kave the old style valve on top which can allow for a overfill. I'm surprised they would fill a bottle with the older style valve, I believe this was a EPA or Federal law that was passed? Those new replacement valves limit how much of a fill you can get at least on those 20# bottles. A float / cut off valve is added I was told by a Blue Rino driver and they only fill between 4 and 4 1/4 gallons in those 5 gallon or 20# bottles. Strange you still get charged the same amount of money vs those older bottles that were filled a full 5 gallons. Must add that propane prices per/gallon are crazy these days and may get worse. My bottles are for the BBQ only, brewing will be with twin 45-5,500 watt elements run on 240 volt for heating. No refill or running out of propane mid brewing besides the price they are asking and driving around for refills. JMO on how i'll heat my brewing system, one less problem in the future brewing process.

I believe MikeFlynn had the same problem kilted. I suggested he turn the burner onto the tank to warm it up.

You're right beemer, there was a law passed and all those old tanks without the overfill shouldn't be refilled. The older style has a valve knob that looks like a star, whereas the new ones have a valve knob that looks like a triangle with the corners cut off.

The propane in that tank is compressed into liquid form. When you release it, it expands into a gas. This is the basic principle for Air conditioners and refrigerators, and propane makes a good cheap refrigerant! The tank is GOING to get cold if you're drawing a lot from it, depending on the amount being drawn, the size of the valve, and the conditions you're in (humidity, ambient temp) it may ice up. Even with a small burner the tank will get cold and covered in condensation after a bit.

AFAIK, they can still be refilled for select purposes. My cousin gets his refilled for torches he uses in his paving business.
