The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

I noticed you did not say where the water was going. That really doesn't matter because a leak like this happens in different places. The key is to find the location and then fix that to eliminate the results. Some start in the freezer and the condensate from the defrost overflow into the freezer. Other blockages are blow the freezer and in a turn going down to the defrost condensate collector pan below the refrigerator. On the link below click where it says how to fix a leaking refrigerator. Read to whole page and if you still have questions let me know. Some parts of that page will not be the information you need so jut use the part that most resembles you leak and the apply the repair.

Er means that somthing is wrong. It could be a temperature problem that caused it. Does it beep at all. That is a alarm for the door being open. You may need to check the magnet on the door and the reed switch on the wall. Upper left for the top drawer. and on the bottom is on the grill and door. Normally this is something I would ask for a tech to look at. But if you feel confident to try this I can get you into the program to see what its telling us. Now hold the up arrow and at the same time press and release the light bulb 3 times. Then release the up arrow last. If you did this right then you will have a 0 on the display. Yes, Then up arrow until you get to 3. Then press and release, It should give you a number. E# ? Let me know what this is. You may have a couple so write down all of them.

Now after you got the number then just push up arrow until you get to 99 then press and release the light bulb to go back to the refrigeration cycle.
E3= bottom drawer open to long
E10= Top drawer open
E1 = Thermistor #1 open
E5 = 10 degrees to warm E6 = 10 degrees too cold E7= Thermistor 2 E8=Thermistor 3 E9 =Thermistor 4 open thermistor 1 located top drawer Thermistor#2 I/M or evap if no icemaker
Thermistor3 is located in freezer or base if no freezer thermistor 4 is drain pan
Hope this helps

temp control is the only answer sorry the unit turns on with it and off with it .

There should be a shut off valve at either the supply water line and sometimes on the back of the refrigerator.
Also, most of the time you can take out the filter without turning the water off and still use the water functions. So if you have a malfunctioning or faulty filter maybe taking it out and leaving it out might do the trick.
You could also check the o ring on the filter and make sure that it is damaged. If the o-ring is damaged find a replacement and see if you still have a leak.

hi kostas.
Condensation runs down the back of the fridge and collects in the gully sitting at the back of the fridge where the water is then channelled through the drain hole into a container which sits on the compressor, it's then evaporated away.

Most frost free refrigerators take water from the freezer so you do not have to defrost the freezer. That being said there should be a drain under the crisper. Check to see if it is clogged.
you may need to put something under the refrigerator to collect the water..

The machine will continue to run water all the time while in harvest mode. The control board blew, and just needs to be replaced. Controls boards can fry without any other signs of anything else being bad. Hoshizaki ice machines dont have a over heat relay that shuts it down upon oerheating if it is the control board

Refrigerators | Answered on Jan 11, 2021

As the harvest cycle (the ice maker fingers rotate to sweep the cubes out of the mold) comes near the end of the rotation, a switch in the ice maker activates to send power to the water valve (located under the refrigerator where the house water supply line connects) and allows perhaps 4 cc of water to flow up a 1/4" plastic line to a fitting on the back of the refrigerator that is aligned with the ice maker inside which then flows into the maker mold. That process refills the ice maker mold and everything shuts off to freeze this water and then initiate another harvest cycle when the entire process is repeated. If there is no water, then there is no ice. Focus on why the water isn't flowing all the way to the ice maker. Look for an ice blockage in the tubing that comes from the back, inside wall of the freezer to the ice maker, or a bad valve. It is rare, but the switch inside the ice maker could be bad. The water valve or a blocked water line are most likely the culprits. Another trick is to pour water into the ice maker mold, wait several hours and see if that freezes and ejects into the pan. If so the ice maker is working, it just has no water to freeze.

The True TSSU-60-16 uses an oversized (134A) refrigeration system with air flow directed at the pans.... if the capillary tube is plugged it will NOT cool at all.. most of the time a restriction (plug) is at the drier where the capillary tube goes into it.. as it is smallest passage in the system...hope it helps

I have a Kenwood tall fridge (KTL60X15) which developed similar faults. It was beeping every time the door was opened (the display showed 88 and all other buttons were lit) and it would beep again when closed. Turns out the wiring from the fridge body to the door had worn out and by the time I discovered the problem 3 of the 5 wires had broken. The wiring can be round under the plastic covers at the top of the door and at the top of the fridge body.. I replace the wiring which was easy to do as it comes as a wiring harness kit (HK1495740) and adjusted how the wiring goes across the top hinge by making a small modification to the plastic covering on the top of the fridge body. So hopefully it won't wear out (at least now I can see it and keep an eye on it).
