Did you mean a LFFH2067DW2?
If so it has an automatic defrost system.
The automatic defrost cycle is controlled by the defrost timer. The defrost cycle occurs once every 8-11 hours (depends on the manufacturer. I don’t know how exactly how often for your model but it should be within this time frame). The auto defrost cycle takes about 20-25 minutes to complete.
During the auto defrost cycle the compressor and the evaporator fan are both turned off and the temperature is allowed to rise to >32 deg. F to melt the ice formed on the evaporator unit at the back inside the compartment at the bottom behind a panel and to drain away to the evaporator pan under the freezer. The melting process is sped up by turning on a defrost heater which is under the evaporator unit. When the temp reaches 32+ F the defrost thermostat operates and the heater is turned off and the compressor and evaporator fan are turned on again to drive the temp back down to the set temperature . The defrost timer is also reset so that the cycle will occur again sometime between 8-11 hours later.
The normal set operating temperature is approx. 0 deg.F
Water/ice problems in a refrigerator or freezer are usually because of a problem with the auto defrost cycle. Due either to a blocked drain tube, a faulty defrost heater or a faulty defrost timer (or control board if the unit has one instead)
If the drain tube is blocked then the ice melt water can not run away and will overflow the bottom of the freezer and also will build up as more ice when the freezer temperature drops again after the defrost cycle has finished.
If the heater is faulty then the ice will continue to build up as enough ice i.e. all the ice has not melted during the defrost cycle.
If the defrost timer is faulty then the auto defrost cycle will most probably never happen so the ice just keeps on building up. Usually there is no water overflow as the temp has never been allowed to rise that far to melt any ice or the heater turned on, but it may be an intermittent problem etc so it could happen
The ice will just continue to build until eventually it ices over the evaporator fan and it will stop running and the freezer temperature will rise due to no cold air being blown throughout to keep it at the correct temp. So the complaint will be freezer too warm ;-)
If everything was working as it should there wouldn’t be that much ice build up in 8-11 hours anyway so not much ice has to melt and drain and then evaporate under the freezer but if there is a problem it may take a few days or more before it becomes evident
Apologies for the long answer but thought that if you understand the process it is easier to know what might be wrong when problems occur.
Here’s a link showing all the parts for your freezer and their location which may help in the future.
I have had a similar problem. Although a different freezer, it worked again after having it defrosted, we ended up getting a technician coming out for a dishwasher, actually, but he checked out the freezer too, and said it was just a periodic maintenance you should do every 6 months or so.

Thanks Esa but I don't think a frostfree unit requires this type of maintenance. At least it is not stated as such in our manual or troubleshooting suggestions. I think that jayeff's response that followed nailed it with his diagnosis.
Mine does the same
Frigidaire commercial upright
Had it on max and it was getting to -10ish and when it self defrosts I think the drain is freezer instead of drawing and the bottom freezes over I see a little puddle of water
I broke up the ice and used hot water to clear the drain but kept occurring every 2-3 months
So I took the thermostat from the highway where it was like -10 to 6-7 and it’s about 10 now and hopefully that works
Just not sure if I should put it to where it gets 0 Fahrenheit if 10 is to warm for a deep freeze

What is the model number of the freezer?
Have an upright Frigidaire model # LFFHU1765DW15. Discovered a sheet of ice in the bottom of the freezer. Melted that w/a hair dryer but there is still a lot of ice behind the back panel. Where is it supposed to drain? Need to see if the drain hose is clogged?
