Marc is correct, you should check to see if you have a blocked filter (this should always be changed when a system is vacuumed and refilled) or you may have oil in the line(s) causing the blockage. But you should know that there is a blockage because your low side pressure will be lower than it should be or in a vacuum and your high side pressure will be much higher than it should be. The blockage could be oil, or a plugged filter or even moisture in the system which will freeze at the end of the capilliary tube in the evaporator which blocks the flow of the refrigerant. But if this was the case the freezer would start to cool down but only for a short time from first start-up then warm up as the capilliary tube plugs up with the frozen moisture. I would suggest that you remove the refrigerant, purge the system to be sure there's no oil etc int he lines, remove the old filter and install a new one, put the system into a deep vacuum for several hours, refill the sytem with the correct amount of refrigerant and monitor it to see if there's a change. Good luck

Can you check if there is a frost pattern on the coils? May be a plugged system line or dryer.

Stand up magic cheef freezer unthawing and hot to touch

A freezer can't "unthaw". It can freeze or thaw. I assume your freezer is not cooling properly and is hot to the touch. First try defrosting the interior. Ice buildup will cause the problems you described. Also check the rear of the freezer and clean the cooling coils so they transfer heat to the outside air.
If neither of these things helps, have a professional check your Freon coolant level. You may have a leak.

Freezeing up, not cooling

Without knowing if it a freezer or a cooler I will have to guess. Could be caused by a few things. I'll list them in order of the one I think is the most common reason.

  1. Door gaskets or someone left door open for a time.
  2. Thermostat set to low.
  3. Low freon
  4. expantion valve out of adjustment or needs replaced
  1. Defrost not working (Will have heaters with a timer)
  2. Low on freon or expantion valve

I have a fridgidaire freezer that is just cooling not freezing?

some freezers will not freeze in the freezer department if you are low on freon. the motor cannot produce enough freon to keep your freezer frozen when it is to low, however, you might have the temperature up to high where it has locked up the motor and is sending out all that water underneath. i would check your pan under your refrigerator to see if it needs to be dumped and then replace it back.

Normal operating pressures

Normal operating pressures will change as the freezer reaches the selected temperatures on the inside. Normals of minus 14 degrees on the inside would be around minus 4 psi on the suction and 150 pis on discharge. Now checking the pressure will require a set of guages that have been purged with the same freon before connecting with the suction line on freezer. If not purged the suction line will draw outside air into the system and cause freezing of air and moisture inside the capillary tube rendering the freezer inoperative, Hope this helps, Sea Breeze
