Does my Green Pan pressure cooker only allow for 30 min. of cook time in pressure cook mode? It only lets me set it for 30 min and need to cook a pot roast for 60 mins.!!!

it is possible that you have misunderstood the instructions
for a slow cooker you have low medium and high
press slow cook and on low and in 8 hours the food is cooked
I see from your statements that you expect the cooker to be set on slow cook but cook at a high temperature fast
if it says slow cook --9 hours and the temp is 125 degrees , have you waited 9 hours to see if it is cooked as the slow cooking process is by the gradual build up of heat in the container that is not expelled by radiation to the air
in a pressure cooker , that build up of heat also builds up pressure and so it cooks better
other solution--- if it is not right return it for a warranty refund or if out of warranty , junk it and get a different make

A pressure cooker is NOT anything close to a slow cooker. The cooking philosophy are practically totally opposites. A pressure cooker basically cooks your food in a fraction of time because it is under pressure. A slow cooker takes hours.

The whole idea of using a pressure cooker is that it is sealed and applies pressure to cook the food faster. The lid needs to be sealed for the pressure cooker to operate properly. It is frequently referred to as "infusion" cooking now days.

You need to read the instruction book that came with the pressure cooker. Pressure cookers usually cook for less than an hour--my homemade pressure cooker spaghetti sauce is cooked in less than 30 minutes. They are nice and were very popular long before anyone thought of microwaves and slow cookers. However, there are some precautions to be taken. There must be water or liquid in a pressure cooker. The rubber seal needs to be cleaned frequently and, when the rubber seal warps/stretches and no longer seals, it needs to be replaced. There are also certain foods that CANNOT be cooked in a pressure cooker like rice, dry beans, etc. The pressure control valve operates to regulate the amount of pressure and releases extra pressure otherwise the unit would blow up (very dangerous!). Most pressure cookers (required on all new ones) have a small rubber emergency stopper that will "blow off" in case the pressure is too high. I've seen this happen and my mother cleaning potatoes & meat from the ceiling!

No one, including the manufacturer seems to be able to answer that question.

The company had a major recall and went out of business. No manuals appear to be available on the web.
Here are some general instructions you can use:

1 Set up your cooker. Place your Ultrex Pressure Cooker on the stove. Remove the lid and pour in no more than 2 inches of water. Depending on what you are cooking the amount of water will vary. More water will ultimately cook larger amounts of food, but you will need to refer to your specific model's instructions on this matter.

2 Put in the food you wish to cook. Close and lock the lid firm to the pot. Make sure it is locked securely so none of contents boil out of the top.

3 Turn on your burner to high heat for approximately ten minutes. Allow the water to boil.

4 Turn the stove down to a low setting after the water is boiling in the cooker. Flip the pressure valve closed and allow your food to simmer.

Set the pressure valve to ten pounds. For vegetables, cook 30 to 45 minutes. For meats, cook 45 to 60 minutes.5

6 Open the pressure valve and allow the pressure to discharge. Unlock and remove the lid to find your fully cooked meal.

I have a Tricity TSC09 6 litre Slow Cooker and I just love it its so handy, if your gone for even 10 hours it keeps your dinner warm after the cooking time runs out. I smashed the lid and was so gutted I tried for hours online to find a replacement lid with no luck. I went shopping and bought a very cheap 6 to 7 Quart or 6 to 6.5 litre Slow cooker / Crock pot of the same shape the removable pot and lid fit. I bought a cookworks, signature, 24 euro 6.5 litre oval dog standard slow cooker and the lid fit, now I also have a removable pot replacement as well just in case I smash that too. So happy I have my Slow cooker back again.

The pressure cooking time for Oxtails is 45 minutes at high pressure. Here is a detailed chart with cooking times for all types of pressure cookers:

make sure u DO NOT lock the clips while cooking, its not a pressure cooker. if you lock the lid the heat and pressure from whatever you are cooking causes an air-tight seal and the lid will shatter or the ceramic pot it self will crack...
