Evaporator drain and bottom coil froze and drain malfunctioned how do I check rest of drain and where is it.

There is a drain pan under evaporator coils that funnels defrosted water into drain pan underneath unit that holds it until it evaporates. The reason you are seeing water on floor is most likely because defrost drain underneath evaporator coils is stopped up. Water can't get out through drain so it ponds in bottom of freezer and eventually out the door.

The drain in the freezer behind back lower panel
needs opening. You can see it at the bottom of the back panel
underneath the evaporator coils. (The cold coils)
Run Hot water in the drain until it clears or use a hairdryer.
When the defrost melts the water it goes down the drain
If the drain is clogged with Ice or ? The defrost water
overflows into the ref. or freezer
Run Hot water in the drain until it clears or use a hairdryer.
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

You most likely have a blockage in the condensate drain line.You should turn off the frig.and empty the freezer,take a hairdryer and melt the ice on the bottom of the freezer.somewhere in the back on the bottom you will see a small drain under the evaporator.you may have to remove the cover of the evaporator to find it.once you locat the drain its just a matter of blowing out the line with a piece of 3/8ths plastic tubeing.

What is a "drain plug"??? Never seen one on a fridge ;)
Clean the drain pan and drain line in the back of the freezer section underneath the evaporator coil. Make sure water drains when you pour it in.
Good luck! :)

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.

We replaced the evaporator motor. Use an Ohmmeter to see if electricity is going there, first, see if fan is running, then, if not, replace evaporator motor-part # 12002744.

Fridge is now running! I'll post again, if there is any more to the story. We are now waiting to see if it gets to temp, but it is running. I'd love to find info on a reset code.

Not sure of your model number and manufacturer, but in some freezer there is a seperate drain heater that should stay on for the complete defrost time. (the defrost heater will shut off when the evap coil reaches a certain temp, and the rest of the defrost time only the drain heater is energized.) That would be the very first place that I would start. Hope this helps

yes they all have a drain pan. when unit goes through defrost your ending up with water on the inside of unit. remove rear panel in freezer to expose evaporator. hole is under evaporator. see if it is froze over

The drian hole has become stopped up and ice has accumulated in the the drian hole. You will need to unplug the fridge and remove the cover on the back (located at the bottom, 6 screws). On the freezer side there is a drian hole with a rubber 90 and a clear line that runs to the drain pan. Remove line and unstop. Don't not put the line back on yet.

Now for the fun part, remove the basket and the two bottom shelves from the freezer. Half way up the back there are 2 screws that need to be removed. After removing screws pull up on the top cover to so you can remove the bottom cover. The bottom cover maybe froze to the coils and to the inside drain pan. Break the ice with a butter knife, and remove cover ( do not hit the coils). Now you need to break the ice that is froze to the the pan and under it. Once you have remove all the ice you will see the drain hole, use a small pointed object to break ice that is in drain hole. Now you can put the drain line back on and make sure that the other end is in the drain pan under the fridge. Now reassemble the fridge and plug it back up.

It took me about 20 minutes to do this.

Hope this helps.

check your evaporator coil in freezer it is froze up ,need to check to make sure defrost timer is working. Also check drain line.
