There is ice build up on back of our bar fridge.
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
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.
you have a defrost
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. Thanks, Sea Breeze

Uline under the counter two drawer refrig seems to
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

How do I shut of the water cause the filter is leaking, i cannot get a spare filter at the moment
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.

Glaciologist commercial ice maker. Why has it stopped making ice?
When a commercial ice machine has is not making ice anymore or makes low amounts of ice, check for the following: Water supply is disconnected See if the water supply valve is turned off or supply hose is disconnected. the Water-float valve and screen are dirty Clean the valve and screen to make ensure proper ice production

Hoshizaki ice machine
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

Water is not flowing into my GSI-23 ice maker.
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.

Capillary tube replacement
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
