Question about Singer 20u Sewing Machine
Singer 20u machine, always worked fine until yesterday. Now the presser foot won't go down. I can see that when the presser foot is raised as high as it will go, the tension releasing lever part # 541700 slips off its lifter, drops down and inserts itself underneath the lifter, blocking the presser foot from going down again. I can push the tension releasing lever back into place and the machine will sew fine until the presser foot is raised to its full height again ie be careful just to raise it part way and it will continue to sew. Is it possible to tighten up or otherwise adjust the tension releasing lever?
Yes indeed, it is possible--sounds to me like a screw worked itself loose. However, I would purchase the service manual for your machine. As a bonus, it tells you how to make all kinds of useful adjustments.
Go to Sewing Parts Online and do a search under Singer Service Manuals; if they don't have it in stock, call or email them and they will be happy to order it for you. Generally takes two weeks to get it in stock.

SOURCE: Presser foot lever stuck
You lever doesn't work because the presser foot Bar is seized from lack of use.Open the side of the machine to access the bar. Put a mixture of water and ammonia ( about 80%water 20% ammonia) on the top and bottom of the bar. Let it sit for 15-20 minutes then try to move the presser foot Up by lifting the foot with a screw driver. Do not pry so hard you break something. It should get progressively easy the more times you do this. Put some sewing machine oil on the top and bottom of the shaft and it should be good to go.

Had the same problem.
Open the cover where the light bulb is.
Follow the presser foot rod up into the machine.
You will find a metal keeper with a set screw facing the now open end of the machine.
That set screw has most likely come loose.
Since the presser foot is spring loaded to the down position leave the presser foot raising lever in the down position.
With your flat bladed screwdriver, gently push the metal keeper to it's lowest position. If it does not go easy, loosen the metal keeper set screw a bit. Lefty loosey.
Tighten the set screw on the metal keeper. Righty tighty.

SOURCE: hello I have a singer model 4552
I have a used unit with the same problem. If you remove the plastic housing piece on the far left you can see how the foot lifter works. Raising the lever raises a collar around the main shaft. There is a screw in that collar which connects the collar with the shaft. If that screw is loose the collar will not raise the shaft. Caution: Tighten the screw very carefully, only enough so that the shaft lifts. I just overtightened and the collar has a crack now.

First, lift the presser foot; next, push the feed dog lever to the raised position; finally, turn the handwheel towards you until you hear the feed dogs snap into place
If it doesn't, you will have to run a maintenance check on your feed dogs,
Unplug the machine and examine the feed dogs. The newer machines have metal feed dogs, but older models may have rubber ones, which often need replacing. Examine the feed dogs and check for damage.
Remove the throat plate, which is the covering over the feed dogs, and clean it with a soft cloth. Use a small soft brush to clean the feed dogs. Make sure to remove all lint and thread from the grooves of the teeth. Some machines have an adjustment that lowers the feed dogs for specific sewing procedures. They should be in the raised position for better viewing during the cleaning process.
Clean the area around the feed dogs with a soft brush. Compressed air is a good choice to use in the small tight areas.
Wipe down all areas with a clean, lint free cloth before replacing the throat plate.
Prepare to clean the feed dogs and all other areas that lint may accumulate on, after every project. Your sewing machine will last longer and need fewer repairs if kept clean and lint free.
Always unplug the sewing machine before any type of maintenance or cleaning.
Never use a sharp tool when cleaning the feed dogs as this may cause damage to the sewing machine.
