Water Freezing Under Evaporator Fan

I have a similar PTC22S model fridge, 6 years old. Water is freezing in a puddle under the evaporator fan, causing it to stall. With no ice to stall it, fan operates normally. Fridge good at consistent 35 degrees unless/until the fan stalls. Freezer at 10 degrees unless/until the fan stalls. Of course, if the fan stalls due to the ice, things multiply quickly.

My first clue is when I can hear the fan start to work away at the ice under it. At that time, I can pull the freezer deck and the only place there is ice is under that fan!

There is no blockage of the drain/air duct down to the lower fridge compartment. You can see right down through it from above.

It's as though the timer is short cycling, allowing just enough time to start some water flow from the coils to the back, but then the water freezes up there instead of being dispersed/evaporated by the fan as it should, but I'm sure open to suggestions. Is it *possible* that for some reason, the evaporator fan isn't being turned ON during the defrost cycle, but works normally at all other times? I'm still looking for the defrost cycle timer on this beast.

    I'm beginning to think that what I need to sort this out is a proper wiring diagram and functional description that shows the interplay between the defrost thermostat (WR50X133), the defrost "control" unit (WR9X490), and the evaporator fan. Unfortunately, there is no wiring diagram on the rear of unit, nor is there one behind the rear panel.

    The fact that the coils stay entirely free of frost/ice indicates that the defrost controller and heater are largely operating as they should. Here's what I'd like to know to troubleshoot this properly vs. just shotgunning the thing with parts:

    1) What is the normal defrost cycle time (approximation OK) for this unit?
    2) Is the defrost thermostat strictly a fail-safe against a failure of the defrost controller to prevent a heater stuck in the "on" state from toasting the refrigerator, or does it assist in determining the "on" time for the heater?
    3) Is the evaporator fan controlled such that it should be enabled during the defrost cycle as well as during normal cooling? If so, where is it controlled? Again, with no wiring diagram, I'm not sure who is in charge here.

Could be a problem with the thermistor or some kinda leak somewhere. It also indicate a fault in the motherboard. Can't say for sure without taking a look.

I'd recommend calling in a qualified technician to take a look before coming to any conclusions or diagnosis.

Cheers!

Clear water coming from bottom of refer.


Freezer /fridge water/ice in fridge

Usually due to CONDENSATION due to bad door seals or a plugged evaporator drain line? Can use a soft flexable tubing and very hot water to clean it out. Bad door seals usually need replacement, but u can use a blow dryer and something to pry it closer to the door wall while blowing hot air on to it. To create a seal, to test for bad door seals place a dollar bill in between the door and wall of fridge where it closes. Then slide out the dollar bill with door closed. It should offer some resistance and not be easy to pull out.
Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.

We have a FRS-U20FA


The water dispenser tube has a low wattage element to prevent the water from freezing in the tube. its normal. Check to see if the evaporator fan is running. Open the freezer door and when the fridge is running, press the switch on the side wall. The freezer light should go out and then you should hear the fan running at the back of the freezer compartment. Common symptoms of a failed fan is ice growing down the back of the freezer compartment , poor refrigeration in the food compartment and partial or poor freezing of food in the freezer. If the fridge is less than 2 years old, it will be under warranty. (Contact Castel Electronics in Melbourne 13
00733962) If its over, they can give you the name and number of a local agent. There are a lot of bits and pieces to remove to get to the fan on an ice and water model, also the rear panel inside the freezer should be removed to make sure ice hasn't blocked the air ducts. If you are not confident in doing it, get one of their agents to sort it out. Cost of fan motor, call and labour should be around $200 to $220

HOT POINT FRIDGE - FREEZER DRIPS WATER


The evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.

Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help. Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the back of the freezer.

the leaking water is the problem. it needs to be fixed, but till then defrost again, use a fan it speeds the process, SHUT OF WTER to ice maker. restart fridge it will work normally. now find parts needed to fix the ice maker water feed.
the leaking water overwhelms the defroster. and causes a coil freeze up, this impedes cooling and air circulation over the evaporator coils

The condensate drain may not be draining into the pan under the fridge or it may have a leak or could even be not connected to the condensate pan in the evaporator.
Another possibility is that your condenser might be dirty or plugged causing the suction line going to the compressor to freeze up and then thaw leaving puddles under the fridge. Clean the condenser (the coil under or behind the fridge) and it should stop.
Over stocking the freezer will cause this as well. If you cover the air return in the freezer the evaporator will freeze up and the suction line will freeze back to the compressor.

Ariston Fridge not cooling - Frozen Coils


Try to check the noisy fan, slow rotation of fan can cause the icing evaporator. Unplug the unit and rotate the fan manually by your finger check if the fan is not misalign or not touching the fan frame. Or check if fan motor bearing is not worn out. Under charge of gas is also one of icing cause.
