Fridge freezing up and no fan or air circulation:

when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..

Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS .

Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?

Refrigerator stopped cooling. As close as I can tell the fan in the freezer part was frosted up for a length of time and has possibly ruined the fridges cooling fan? Kenmore model 106 freezer on top.


If the fan in the freezer stops, then coll air from freezer will not pass from freezer section to fridge section.In that case, the freezer section will get over frosted but fridge section will not get cold, because cool air will not pass from freezer to fridge.The fan is there for two things, 1) for cooling the heating evaporator coil and 2) For flowing the cool air from freezer to fridge.---------- If the frost is getting collected and fan is getting stuck up in frost, then this is the problem.The defrost cycle is not running, the cooling cycle is running.---------------
This problem is called defrost problem.-------------

So first thing you try is , perform, manual defrost reset procedure.---------

The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

My samsung refrigerator is building ice in both cabinets.the fan works ,the heater is also good.what i can't test is the end defrost relay. what do you propose me how to test and resolve my problem?


Here's a link to a very good explanation of the defrost circuit. You can check the defrost terminator by disconnecting it and measuring with an ohm meter. The relay contacts can be checked with the ohm meter if you unplug the fridge and manually advance the timer. The motor and and other parts will be checked with a volt meter at different points in the cycle with the fridge paoered up and running. If you're building up ice, there's an issue with the defroster circuit - or the defrost drain tube is clogged with ice.

If the defrost circuit is working and tube is clogged with ice - thaw it out. Hang an aluminum or copper wire from the defrost heater into the drain tube. Make sure the wire hangs slightly further into the tube than the ice formed inside. This wire will help conduct heat during defrost mode down into the tube and help prevent ice from forming.

If this was helpful, please rate it "4 thumbs up". Thanks!

Where would i locate defrost timer on my ge bottom freezer refrigerator


Older fridges use a defrost timer to control when the fridge goes into defrost. Yours is a newer model and uses a control module which controls all of the fridge's functions including defrost timing. It does not have a defrost timer. It cost around $150. But I would check the defrost element first. A lot of problems with the defrost are usually a burnt out heating element. Use a meter and check that the element is not electrically open.

Samsung model RB193KASB Fridge seems to be not as


Hello,
Insufficient cooling is a fridge repair job that you can do without the help of a professional. Often the fridge has a frost-free failure, or the compressor is faulty but there are many other reasons for a fridge not cooling properly.
Step 1 – Find the Problem

Your first job is to locate the source of the problem. Consider each of the following:

* Gaskets - Make sure the gaskets/seals are not torn and are sealing properly.
* Evaporator fan – Make sure it is working. If it is now working you may have a problem with the fan motor. Check for power to the motor and also examine the fan switches around the door (not all fridges have these switches).
* Air damper – Sometimes the air damper will not open up to allow the cold air from the freezer part to blow into the fridge section.
* Condenser coils – Check to see that the condenser coils don’t have a dust build-up and that the condenser motor is working.
* Compressor – Make sure your compressor is working with on and off clicking noises.

Step 2 – Frost-Free Failure

This is the most common cooling problem in fridges. Expose the evaporator coils by accessing the panel in the freezer section. The coils in the freezer section can sometimes get clogged up with frost. This can stop the evaporator fan motor from blowing cold air around, or cause the fan to hit it and stop, or become noisy. The defrost timer can be a bit tricky to find but it is usually located behind the back bottom corners of the fridge, although they can sometimes be found in the ceiling of the fresh food section, or behind the cold control cover.
Step 3 – Find the Timer

When you find the timer, turn the wheel-like screw slowly with a screwdriver until the fridge shuts off. The refrigerator is now defrosting. If you find that the fridge starts now, you will need to replace the defrost thermostat and the defrost timer.
Step 4 – Volt Test

If the heaters do not come on, use a volt meter to ohm test the defrost heater or volt test for 120 volts to the heater. You can bypass the defrost thermostat if you haven’t got power to the defrost heater to check if the defrost heater will come on. To bypass the thermostat, join the two wires together. Replace the defrost thermostat and the defrost timer if the heater comes on now.

If there is a ticking or squealing noise in the defrost timer, or it seems hot to touch, replace it.

Many fridges have and inline fuse on both sides of the defrost heater. You will need to replace the whole heater if one of those fuses blows. Check these fuses with a volt meter if the defrost heater doesn’t work.

A quick check if you have a cooling problem is to inspect the evaporator coils. If there is a build up of white snow on the coils, this indicates a frost free problem; if there is balled ice on part of the coils with the rest bare, this indicates a system problem, like a problem with the pumping compressor.

Hope this helpout...

Automatic defrost no longer works


If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

Kenmore side-by-side freezer is fine but fridge is not


Yes, Airflow is what cools the frig. Check for frost buildup on the coils indicating a problem in the defrost components r a fan not running fast enough. Eric
