Turn the timer slowly clockwise until the compressor and fans stop. Leave the timer alone in that position that turned the compressor and fans off for up to 35 minutes. In the first few minutes after the timer turned fans and compressor off you should be getting defrost. If timer comes on by itself and you have defrost results the timer and defrost heater are good. If the timer does not turn the refrigerator back on but the defrost took place then replace the timer. Every different refrigerator or freezer has a different amount of time on for cooling and time off for defrost so it is important to know what the model number is to answer the part number and time off/on ratio. What is the model number of the refrigerator that the timer is on? Sea Breeze

Freezer coils are frozen up and the evaportation fan is working. Where is the defrost heater and what does it look like? is what one looks like (since you didn't give your model number - couldn't look up the one you need) It is item 58 on the diagram, but again not your exact schematic. The defrost heater is normally located very close to the coils.

But if you test your defrost heater and it is good (see video on first link on how to test) then you might have trouble with the thermistat - or the timer - and some whirlpools even have a defrost control board -

Hope this helps!

Here is a new control via e-bay: ($99.00)

This is the chinese generic version of the timer:
R 8004-TMDE706SC Problem is.... it is so generic that you must sort out defrost time required periods 115V 230V or 240V.

I have to be honest... you can probably walk into any reputable applicance parts source and find a generic timer much cheaper. (Match them up) What is the model number of the compressor? Per the timer specs.. you should have a 1/3 hp compressor. The LRA (locked rotor amperage) number on the side of the compressor is probably around 21.7 Amps. The failures on older equipment are run capacitors, and PTC relays / thermal overloads. There should be 3 posts on the compressor. C, R and S. You should read winding resistance C - R and C - S you should NOT read resistance C, R or S to chassis ground. (C maybe if it is internally grounded) If R or S read to ground the compressor has failed. Again if you insist on keeoing the unit you can get a generic 1/3 HP Embraco (or another brand) compressor.

Gallery side by side. Ice forms within a week after cleaning it out. Forms just above the vent area.

Hello, This sounds like you should look at 2 parts. Check your schematic which is usually glued to the motor compartment and look for the Dryer Heater and the Cycle Timer. The Cycle Timer is a device which triggers the Heater in Self-Defrosting Refrigerators. You need to determine if it is working, some have a external twist button which can be used to engage the Defrost Mode. The second part is the heating element which is turned on by the Timer. It is usually within the cavities of the inner shell of the refrigerator box.

Although all Refrigerators are meant to cool and freeze, the Self-Defrost models regularly generate a small amount of heat to lower humidity and to keep the box from icing up as yours has done.

I have had good experience with a business called Servall, which has service parts for all major Appliances. They may be in your phone-book, they are on the Web, and they have an 800 number. You may be able to obtain schematics and info from them and they have been in business since 1929.

Another source of diagrams can be your Library. There are repair books for major appliances there, even by Brand. I hope my solution is very helpful to you. I do not have Servall's number at hand, but it is an affliation of Service companies and one may be a local number for you. If you can find the schematic on your unit, a continuity test will tell you the condition of the 2 parts I mentioned.
For the timer, it must be turned to an active position to register.

Kenmore 10674264400. What is the correct wiring connections for the defrost timer board?

here is no specific wiring diagram available but I may be able to help you with this problem.There are tech sheets with wiring and tests available for most model refrigerator.
From the description you give you most likely have a defrost problem. If the defrost system stops working then ice builds up on the coils and eventually causes air flow and cooling problem. If you have a top mount refrigerator the the instructions to enter and run the defrost system are in the image below.
The heater can be checked for how many amperes it's drawing or just listen for the sizzle and pop as the ice melts around the heater.
A defrost failure can be a problem with the timer/control, element or defrost thermostat.
I include additional wiring schematic diagrams of other brands (Maytag), you can compare, wiring connection of the defrost system using adaptive electronic defrost control board instead of the timer.
I hope this information helps with this problem. see in my Blog for more info and submit another question with any additional details for further assistance.

Maytag refrigerator, feezer side coil frozen and frigirator not

Defrost circuit failed, needs to be able to defrost the coils so air can pass through them thus cooling evenly. You can check the heaters located on the coils probably near the bottom back wall of the freezer with a ohm meter if you read through, the heaters are good, if you get no reading the heaters are bad. Or could be defrost timer or on newer models the adaptive defrost control which is a circuit board. If its an older model you can manually turn the timer with a screwdriver if you feel resistance, then you should replace the timer. Also in the circuit is the defrost thermostat located on the coils, this is the least expensive of the 3 components to replace. You should have a schematic located under the fridge, use this to determine which type of timer you have and for further trouble-shooting. Please let me know if this helps

Bottom freezer works; Top fridge too warm

The defrost timer is about 6 inches square and about 2 inches thick. It could be located under the box, in front or back. Some models of Whirlpool and Kenmore locate it behind the cover over the light inside the box. Westinghouse is often inside the cooler compartment, in the top. Some Gibson boxes put it in the back, about chest high. It's often hidden, but every self-defrosting refrigerator has one, except for a few models of Whirlpool and Kenmore with factory-installed ice makers — these models have an icemaker which also has the defrost timer built into it. The timer will have a stem that protrudes, or may be flush, which you can turn using a large blade screwdriver. Mark the position with a pencil, then turn it until it "clicks." This should start the defrost mode. The defrost mode will continue for 10 to 30 minutes, depending on the design. If after 20 minutes, the refrigerator has not restarted, or the timer stem has not moved, the timer is bad. When replacing the timer, you must use the correct one. There are about a dozen different configurations with even more types of connections. I suggest you order the part by make, model number, and serial number of your refrigerator to make sure you get the right one. Depending on your brand, and where you purchase the part, the price may be from $20 to $40 for this part.

You can test the termostat,just see if the fridge goes on and off..
If it goes off then the defrost heater sould go on.
The best way is to replace both the timer and thermostat...

if a evaporator gives any problems then the fridge wont cool down.

Hope this helps..
