Frigidaire Upright Freezer Seems to Always be in Auto Defrost

We have an upright Frigidaire freezer, model FFU2064DW1. Seems to be in the auto defrost mode a lot. Inside, 10 degree air blows from the vent, but some foods are soft (ice cream, bread). Meats hard as a rock. Coils are in the walls and when defrosting, the outside metal is warm on left and right sides and reads 88 to 90 degrees. Also, lots of water filling the drain cup completely. Water also dripping from where the tube to the evaporator goes up into the freezer. Seems like it's trying to cool the freezer portion while defrosting the coils at the same time.
Defrost timer bad? Or thermostat?
I welcome any advice.
Thank you for your assistance.

Temperature of external freezer surface is warm The exterior freezer walls can be as much as 30F warmer than room temperature. This is normal while the compressor works to transfer
heat from inside the freezer cabinet.

That is right out of your owners manual.

A storage freezer should be kept closed as much as possible. The coil instantly ices as soon as warm humid air hits it. Most units defrost three times a day. The door gasket is also critical on a freezer for proper operation. Any leaks are a problem. Your freezer needs to be down around 0f for proper food storage.

Have you tried setting the thermostat colder ? Did it get colder ?

If not, it could be a defrost issue where the evaporator coil inside is not unthawing completely.

Thanks PJmax. Yes, changed dial from 3 to 4 and it did get colder, but still seems to be defrosting a lot more often than it ever has. We hardly ever open the door.

If not, it could be a defrost issue where the evaporator coil inside is not unthawing completely.

Is this easy to check? I can remove the panel inside on the bottom part of the freezer to get to it.

Yes.... remove the panel in the back bottom to see the coil. It should not be heavily iced. It would probably be a good idea to manually put the freezer into defrost and see if the coil heater is actually heating the coil up. I think the defrost timer is in the lower back of unit.

If it turns out you do have a lot of ice....also check the bottom of the door gasket for leaks. This is a constant cause of trouble on these units.

Coil was free of ice.
Bottom of door gasket appears to be fine.
There isn't water under the freezer any more. The drain cup had about 1/4" of water in it.
Seems to be working normally.

If it acts up again....check the coil for ice.
