Defrost heater The evaporator will freeze up with lots of ice. The defrost heater is getting hot, but not glowing red like I have seen on other elements in the past. Is this one supposed to glow red?

Summit refrigerator top freezer model FF1625SS evapator drain hole keeps icing up and there is a wire to transfer heat to drain inlet.


Hi, One of the most common problems with frost-free refrigerators (and often with upright frost-free freezers) is drain freeze up. This is usually caused by the defrost drain clogging, then freezing. On older units, it can also happen when the insulation (usually open-cell Styrofoam) around the drain gets 'water-logged', as it often does over the years, causing ice to build up inside the drain.
The first symptom, at least in top-freezers, is usually water under the crisper drawers, on the floor of the refrigerator section.
In side-by-sides and upright freezers it'll appear as a nifty slab of ice on the freezer floor, eventually running water out onto the kitchen floor.

These are quick and easy to make. Just cut a piece of #12 copper wire (strip from regular 12-2WG 'Romex' household wire) about 6 inches long and bend it around a 1/4 inch round rod. A screwdriver shaft works well for this, but any 1/4 inch dia. piece of metal will do.
Now when your refrig or freezer drain clogs and you find the trough under the evaporator full of ice, here's what you do.
Clear the
ice, open the drain (use hot water in your one gallon pressure sprayer and a wet-vac, and hang this little piece of copper on the defrost heater, so it extends down the drain. On most units, this is a black rod under the evaporator coil. Some use a radiant heater inside a glass tube, with which you can use this method, but you must carefully bend the hook on your copper wire to the diameter of the glass, being sure it puts no pressure on the glass.
This heater is responsible for melting all that frost that we don't have to deal with since the advent of Frost-free units, and it glows a dull red during the defrost cycle, so there's plenty of excess heat for our purpose.
Anyway, since copper's such a good conductor of heat, some of the defrost heater's energy will transfer down the copper wire, into the drain, and keep it open. What I like to call 'stupidly simple', this uses no extra electricity and works extremely well!
One precaution: hang this piece of copper *loosely* over the defrost heater. Don't squeeze or crimp it on, or you risk causing a "hot spot", damaging the heater.
Note: I get a lot of questions as to whether this wire will melt the rubber drain grommet or plastic drain tubing. I've installed literally hundreds of these wires (wish I'd kept count!) and have never seen any damage caused to those areas.
Keep in mind that when the unit switches into defrost, the inside of the freezer is at or below zero. Most defrost cycles last 20 minutes max, with the heater shutting down before the cycle
ends, so the warmth that travels down this little copper wire isn't nearly intense enough to melt anything but ice.

Hope this makes sense! Good luck
David

I bought a maytag side by side in 2002; model # MSD2454GRQ, SN 18157432AL, REV # 18. Ice is forming at the bottom of the maytag freezer department. Overnight ice will form at about 1/8 inch and left has...


Defrost problem: 3 components. Defrost Heater. Timer (circuit board or motorized) & Thermostat.
Remove cover on the inside back wall (usually 6 screws). Note frost pattern. (bottom of evaporator coil)
Put refrigerator into defrost cycle and note the defrost heater come on, or not. (careful heater can glow red hot)... Unplug Frige and test defrost components. Replace bad component... Refrigerator should defrost every 8 hours. when the cycle slows or quits the freezer will freeze over the evaporator coil and no air flow = no cold air...

Won,t get cold freezer side not freezing it is a ge side by side . ice is present at the back of freezer side


The problem is most likely the defrost heater element(s) and/or the defrost timer. The defrost heater element(s) are located with the evaporator core behind the access panel inside of the freezer, and can be removed, tested with an ohm meter, (any reading other than infinity would most likely mean the heater element is functional) and replaced if necessary. The defrost timer can be located inside of the refrigerator, or outside of the refrigerator behind the front kick panel, or behind the rear access cover on the back of the refrigerator.

Usually if the evaporator core is freezing up and not allowing air to flow through the evaporator core, (necessary for the system to function properly) then the defrost timer is most likely working and the defrost heater element(s) would most likely be at fault.

Always place a towel on the bottom of the freezer and use a blow dryer to defrost the evaporator core and never use any sharp or hard objects to pick away the ice or the evaporator core can be damaged and the refrigerant will be leak from the system.

I have included some images to help assist you including an image of a defrost timer that is located inside of the refrigerator, and a new defrost heater element or defrost timer can be purchased from an appliance parts distributor.

Let me know if you require any further assistance.

This is a new fridge and the element located in the lower freezer behind the pull out drawer is red hot with water dripping on it? we had the same problem with our old fridge and this is why we replaced...


the element you see in the back of the freezer compartment is the defrost heater. your frig will defrost 2-3 times every 24 hours for 15-30 minutes. when its in a defrost cycle the element will get hot and melt the frost that has built up on the cooling coils from normal operation. the melted frost will then drip down ..some will hit the heater and sizzle,most will drip onto a tray and go down a small drain into a pan under the frig and then evaporate out.. Also ,it doesnt defrost at the same time each day., it is based on how much the frig runs and the electronic control will figure out when it it time to initiate a defrost..the red glow and the sizzling is normal and only lasts a short time....

I have a ge side by side model tfx24s the freeze is leaking and i removed the lower tray and seen a coil get glowing red is that common


Yes, the glowing red would be the defrost heater doing it's job. (it usually is on for maybe 20 minutes once or twice a day to defrost the coils) There is a drain hole, about the size of a quarter at the center, just below the defrost heater which can block up, causing the defrost water to flow out onto the freezer floor and eventually out the freezer door. Use a turkey baster with hot (not boiling) water to flush the drain open. If you can't reach the drain, try a section of tubing pushed onto the end of the turkey baster to add a flexible extention to your reach. The defrost water normally drains into a pan under the refrigerator where it will evaporate.

Ice build-up in lower freezer. We replaces the


warm between doors is normal. if hot then clean coils and if coils clean make sure condenser fan motor working thats the fan in the back compartment, however if warm thats good. did the evaporator coil freeze from top to btm is that why u replaced heater. if it was then could be heater,if the coil is only getting frost on half the coil,you could have a sealed system problem. is the evaporator motor working in the frz side if not,then that could be the problem.if coil is froze up it needs to be defrosted. did you defrost coil when you replaced heater,if not try defrosting coils and then wait about 12 hrs and see how it does.

all is normal with the defrost heater getting red hot.

as far as the inlet tube freezing, you most likely need a new water inlet valve. it may not be closing all the way and water is slowly dripping into the icemaker and freezing up right away. a new valve should fix your issue. here is the part that you need. http://www.repairclinic.com/SSPartDetail.aspx?s=t-TFH27PRSA-%3d%3di1032629&PartID=1032629
