Freezer forming Ice on the bottom not draining water

dependant on appliance you may have a small drain hose at the base of the appliance that drains the defrosted water away at regular intervals. Sometimes this blocks and the water that should drain away just starts to freeze over.

There is a drain the back of the freezer that is frozen. Your trickle of water comes from the ice that melts off of the refrigeration coils during the defrost cycle. You need to turn off the freezer, then remove the rear cover from the back wall to expose the coils. With a hair dryer, melt all of the ice. You will find a drain under the coils. Melts all of the ice in this drain so water can get out of the freezer. When this drain is clear, you can put everything back together, and your freezer should work normally.

Make sure the condenser fan is working.

Either the drain hose is plugged up with ice and not dripping into evaporator tray, or the defrost unit needs to be replaced.

Either your defrost timer, defrost heater or defrost thermostat has failed. All parts are located behind the lower back panel inside the freezer. Most likely are the defrost heater and defrost thermostat.

it sound like your unit has a bad sensor on it or a leak. you should never have to add refrigerant to a unit unless theres a leak then it has to be repaired firdt the recharged.

looks like low on freon. that causes freeze up. oddly enough they freeze up when charge is low , just the opposite of what you think they would do. you have a freon leak unfortunately. probably not accessible, and therefore not repairable. i would suggest, cut your losses and buy new. unfortunately for me and all other srevice techs, the days of affordable repair are over, you can now replace cheaper than i can fix and have a warranty and its new... good luck

The drain has most likely frozen over. It is at the bottom behind the back panel inside the freezer. You will need to remove all of the ice and run hot water down the drain until it is clear.

thius suggests the defrost system not working and the defrost drain blocked. take off the back panel inside the freezer, melt off excessive ice and free the drain at the bottom with hot water and patience
