HOW LONG DOES DEFROST STAYS IN - Nor-Lake Freezer Norlake Refrigeration 6' x 6' Kold Locker Walk-In Freezer - 6' 7'' High w/Floor

how old is your model you have. a weak pump will make the system slower to get to temp even a broken seal can do this. even just a few mil gap can make it do this. if you close the door then re-open it it should be harder to open the door. this is the seal being nice and tight to its fittings.

Remove the housing that covers the evaporator inside the fresh food section and remove any ice or sludge that may be blocking the defrost drain below that evaporator. Insure no ice or water is touching the defrost sensor for that section. This is a common problem that Samsung has with it's dual evaporator refrigerators. With that drain blocked the problem will only become worse.Thanks Sea Breeze

Your fan unit is blocked, draws freezer air from freezer, may be defrost element or defrost timer, needs service machanic, sorry. Russ

23 degrees definitely no good. Your getting some refrigeration though so compressor probably OK. Could not be seized. This may not be a hermetic system .you may have lost some refrigerant.But sounds more like your not defrosting .Have freezer guy check for manual defrost switch or defrost timer .
Re post with more information for more help

cheers

defrost cycle is innactive, will ice up shortly and may not turn compressor off, defrost the unit totally(Turn off for 2 days with door open) and remove all water from the unit once done. Restart unit and should work normal for a week or so, ie...defrost cycle...get back to me if this is the case and will sort it from there, [email protected] Russ

ic Defrost Thermostat
This is the component that controls how long the heater stays on when the machine is in defrost mode. Say the defrost cycle is thirty minutes, the heater may only be on for ten of those thirty minutes on the timer controls. On Adaptive Defrost Controls, when the heater shuts off, shortly after the machine exits defrost mode. Basically if the heater only stays on for ten minutes, the whole defrost cycle will only be about 12 or 13 minutes longe is continueing to build up due to one of the defrost cycle parts not fucntioning properly this is the most likely piece to be causing your ice up issue do a continuity test on the thermostat to assure that it is working properly
Basically when the heater comes on, it starts to melt the frost on the evaporator. Once all the ice and frost is gone, the temperature behind the panel will start to rise. Once the temperature behind the panel rises to a certain temperature, the thermostat will break the current of electricity going to the heater. Bam, it shuts off and prevents your freezer from becoming a sauna, or an oven. I'm sure you get the drift. The heater is on the bottom of the evaporator coils and the defrost thermostat sits on top of the evaporator coils.
Defrost Heater
This is the last component in the defrost system. This one should be pretty simple. By now if you have read this far you should already know what this does and how important is it. Some defrost heaters are a coil of wire in a glass tube under the evaporator coils. Works like a light bulb basically. The other style looks like the bake element in your stove. They both get red hot either way and melt the frost
Defrost control or timer. Some refrigerators have a defrost timer. This type works like a clock. Every eight hours or so the machine hits the defrost spot and that's when defrost occurs

Some refrigerators have an Adaptive Defrost Control. This is what makes a refrigerator energy efficient. It varys the length of time it takes the machine to go into defrost. So instead of the energy hogging heater coming on every eight hours, it may be 24 hours, 18 hours, 10.5 hours, who knows. It depends on how many times you have opened the doors, how long the compressor has run. This is good because the refrigerator may not need to go into defrost every eight hours. Now you are saving energy.

and lastly there is the fan also if it is not working will not allow the flow of air to leave the inside of the freezer. Continuity test can also be done on the heater as well and the least likely would be the timer to go bad in some models they have a board on the back of the machine instead of a defrost timer if you have any further questions please message me back and please remember to rank how this opinion has helped as well Thanks again Rick

Defrost drain is clogged. This accessable thru the back wall of the freezer. Also depending on your model some also have removable Bottom floors of freezer that also get ice accumulation. When the defrost drain gets clogged water from the defrost cycle has no where to go so it stays and accumulates ice till eventually it leaks into the fresh food section. Clear the drain completly and you will have no more problems.

have you checked if the fan is running in the freezer??

if not, check if fan connected to defrost thermostat, if it is suspect defective defrost thermostat but try the fan directly if it doesn't go on, suspect bad freezer f

Try advancing the defrost timer manually.

replace the mother board part number wr55x10552. it located on the back of the frig
