Defrost Problem - evaporator completely frozen

On 11/19 "the Dr" helped me with a problem where it seemed the condensate drain was frozen. All seemed well.

This morning I discovered that the freezer was about 20 degrees. The back of the freezer was covered in frost. The evap was frozen solid, I defrosted it with a hair dryer.

I had this problem when it was several months old - the tech replaced the "Defrost Terminator" - a small sensor mounted on the back panel of the freezer.

Re: Defrost Problem - evaporator completely frozen

I know i think in the fridge part (atleast on mine) there is a knob for temp.

if that doesnt work i guess you need another defrost terminator

Will it shut off automatically if left on too long and water runs out?

Hello Tara;

My name is Peter. I am a retired field service refrigeration technician.

The normal cycle for a refrigerator is for the unit to completely shut down (with the exception of the lights) every 8-10 hours. At this time your freezer defrost heater will turn on for 20-30 minutes to defrost your cooling coil. At this time condensate (water) will run into your drain pan. This water will evaporate or time.

If you have water running out on the floor and ice on the bottom of your freezer, then you probably have a frozen drain.

Tell me more so I may help you if you have a problem.

Does a bosch fridge freezer always have water in the evaporation tray?

Hello Mary;

My name is Peter. I am a retired field service refrigeration technician.

It is normal to have water in your evaporator drain pan.

Your refrigerator goes through a defrost cycle every 8-10 hours, where your refrigerator will shut down for about 20 minutes and your defrost heater turns on.
You do not need to clean your drain pan. You have a condenser fan that blows across the drain pan to evaporate the condensate.

You drain pan will fill during the defrost cycles. the condenser fan blow across the drain pan and will evaporate the water.

The amount of water in your drain pan will depend on conditions such as high frost in the freezer.

Mary, you had just happened up the drain pan not completely evaporating the condensate.

Sounds to me like you are in good shape.

This is a very common problem with Samsung refrigerators especially the type that has two evaporators. The evaporator that is inside the fresh food section and will usally give people the most problems. The drain below the evaporator in the fresh food section will begin to freeze over or become blocked by gunk inside the drain line. When this happens it causes the fresh food section to retain water because with the drain blocked the moisture and defrost condensate water now have nowhere to go. Once that drain is blocked the freezing over of the evaporator will begin to happen more often slowing down defrost which again make problems worse. Clean the drain, make sure the refrigerator is level and confirm the model number of your refrigerator. Your model has no defrost timer and defrost are determined by the motherboard. There is a way to force defrost with your model from the motherboard but until the drain is cleaned out defrost will not help much because the water has no where to go but to freeze over the evaporator and fan area of the fresh food section evaporator.

Is RS261MDWP the correct model number? If you left the freezer door open there is an excess amount of frost covering the evaporators because moisture was drawn inside and has frozen on the evaporator and is too much for a normal defrost to get all of the ice off and drain into the pan below the refrigerator. It may have also frozen over the condensate drain and not allowing the water to drain. You may need to clean the drain hole and defrost the refrigerator manually and insure the evaporators are clear of backed up water. If you don't there is a chance the refrigerator will continue like this until you do. Let me know what the status is so I can help.....Sea Breeze

Manually defrost the evaporator and clean the defrost condensate below each evaporator. If that drain becomes blocked it will cause these problems to happen because when water has nowhere to go the water will freeze on the evaporator. I have seen these symptoms in many Samsung RS2630SH models. Let me know what you find, Thanks Sea Breeze

Water dripping into the refrigerator

Sounds very common. Without seeing your refrigerator I can only imagine that you have a drain pan leak below refrigerator, defrost condensate drain line loose or missing the drain pan, frozen over drain opening inside rear wall of freezer or the defrost condensate line is blocked somewhere along its route to the condensate collection tray below refrigerator. I am not finished so plaes don't rate me until I complete. Sea Breeze

you may need to manually defrost the evaporator coil. If condensation built up from the door being left open, it may have frozen the coil solid. At that point even the evaporator defrost bar won't be able to remove the ice. Remove the cover, if it is frozen solid, unplug the unit and use a hair dryer to defrost the ice.

FRIGIDAIRE frost free refrigerator seems to be leaking. Items in freezer are frozen...items in refrigerator are cold...any ideas? It has an ice maker which is working. Approx. 13 years old.

Your 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 lower back of the freezer.

Kenmore upright freezer

you have a defrost system problem. Could be the defrost timer or defrost heater or defrost thermostat. Bottom filled with ice could be from a plugged drain system. Where you termed "condenser coil" is in reality the "evaporator coil".

most likely the drain is plugged try using some low pressure compressed air to blow out the tube, yes the heater is what defrosts, no hot gas, other than that the icemaker fill tube could be leaking, freezing the drain.
