Freezer is getting hot on the left, right and front parts of the exterior, but it is freezing. I t did not get hot in recent years.

You will need to turn the unit off and let it completely unthaw. There is frost that builds up in the ducts and behind the panels when the door is left open that will cause the unit to not cool or circulate where needed.

Make sure the evaporator coils on the back or underneath near the compressor are clean. If there is a fan near the coils make sure it's running.

how hot is the compressor? a very warm to hot compressor indicate dirty coils or lack of refrigerant

I have a Scandinova chest freezer and the left hand side froze, but not the right side, because the compressor in the box under the right side of the freezer was getting so hot, a small amount of heat was conducting back through into the right side of the freezer and preventing anything on that side from freezing!
I solved this problem by running the compressor outside of the of the freezer box, by taking the air vent off, unbolting the compressor and then pulling out by about 20cm and running it from there.

Hi, can you put your hands on front of freezer, and check from 1 to 5 without getting burn? how long can you keep your hands on front of freezer? check from 1 to 20 and let me know, normally there's a condensate line, or part of condenser lines that passes through freezer body , purpose of those condensate line is to prevent your door gasket from freezing , especially during winter. It's normal for front of freezer to be warmed, on hot days it will be a little hotter, you said "very hot" makes me wonder how hot it is, put your hands on front of freezer, use number method and let me know, but it's normal. good luck.

have you cleaned the bottom of the freezer from dust that gets under there so it can breathe

This is normal. The refrigerant lines run through the sides and get hot.

no check the air thats being blown by the fan in the freezer can you feel any cold air and i mean cold? if not go to the back of the fridge taKE Off the bottom panel should have like 6 to 10 screws see if the fan in the back is working  if yes see how hot the compressor(the big black thing next to the fan, sorry some people dont know what it is) see if its hot if it is very very hot like burn your hand hot you can try to cool it down with some paper towels and cold water but unplugg the fridge if its warm not so hot or cold than you need to get a 3 in 1 kit  your compressor is not turning on because the starter relay is not good and its not helping the fridge turn on the relay is very very easy to install once you get it youll have to take off the black plasticon the right or front side of the compressor there are two plastic parts that are on the compressor under the big black part ( you might not have the black plastic if not just do this step) take the plastic parts that have the wires attached to it put the kit on on the kit there are three wires with metal little parts at the tips fallow the directions and place them on the right part of the  compressor there are three metal sticks about less than an inc big and you have to put the three wires on each one FALLOW THE PICTURE black on the middle on and depending if you middle on is on the top or bottom would depend where you put what color wire if you middle one is at the top put white wire on the left and red on the right and if you middle one is in the bottom black goes on it and white on the right and red on the left but like i said fallow the directions
than you have to strip the other two wires that are left on the kit than take the two wires that you took off with the plastic parts that were on the compressor once you cut them strip the wires and just connect them to the two left over ones from the kit doesnt matter which one goes where
sorry for the long reply but this should help
if you do the 3 in 1 kit and the compressor turns on and after a while like an hour it doesnt feel cool air at all than you have a freeon leak which mean new fridge
the 3 in 1 costs like 20 dollars
good luck keep me upadated

how old is it ? and if is just humming is etheir a locked compressor wich if it is then depending on age if is less than 5 years from todays date then just call frigedaire and they will fix it for free but is it was manufacture more than five years ago then is trash , now is just the overload then just buy the part and replace it and you will see if it turns on the overload is the part siiting right on the left side on compressor , fyi the maunufactures date is on the name plate on the wall i belived is on the left hand side

This is a normal condition.  The condensor coils are in the cabinet and their job is to remove heat which is why it is hot.  You will want to make sure the freezer isn't in a tight spot where air from the room can't flow across it.  Without good air flow it will become too hot and not cool properly and lead to the compressor failing too soon.
