Question about Frigidaire FFUS2613L Side by Side Refrigerator

2 Answers

I have a Frigidaire FFUS2613Land can't locate the defrost timer, can you tell me where to find it. The unit is frosting up and the refigerator is not cooling, I checked the defrost element and the bimetal and they are good. Just don't know where the defrost time is to test that. The temperature control is also not responding to adjustments and even when you try holding down the OFF button for 3 seconds to turn off the unit it goes off 1 seconds then comes on again. Please help.

    Thanks for the info,I think it is the control board as the other parts checked out to be okay and the controls are not doing what they should do like adjust ingthe temp and turning the unit off after pressing the button for 3 seconds,instead it goes off and comes back on for itself right after.

    Hey guys, thanks for te info.

    I'm convince that it is the control board, I live in the caribbean but purchased the unit in Brooklyn last November and had it shipped so it will take me a while longer to get the part.

    As soon as I get the part I will install it and let yo guys know.



  • rantoine1 Apr 11, 2011

    All, I got the control board last Friday and installed it myself the same night and it's now Sunday and my unit is working fine.
    You guys made it a lot easier for me, I had called a technician guy and he never came.
    I will advise anyone to try these repairs at home themselves with your support.
    It saved me a lot of time and money, the board cost me about $67USD exactly $430.00TT.

    Thanks again.

Hello Rantoine1,

I understand that you are having a problem locating the defrost timer.

The unit does not have a separate defrost timer the defrost timer is made in the temperature controls and works thru the light. You will have to make sure that the light works in order for the defroster to work. But as you have stated that you are having a problem with the temperature control board then operates the defroster. You will need to change the temperature control on the unit. The cheapest place that I have located the control board is at Sears Parts Direct here is the part number 241739702 the cost is $92.99 on the following

You can also go to this link to see if you can find a parts distributor close to you that you maybe able to visit and pick up the part right away

To replace the temperature control:
1. Unplug the Refrigerator
2. Remove the three screws from the bottom side of the control housing
3. Drop down the housing remove all the plugs from the control board
4. Place the new one and reverse the directions

Thank you for choosing

You don't have a defrost timer, you have a control board which controls the defrost cycle. It's part 23 in this DIAGRAM

Here is a description of the defrost system but basically if your heater and defrost thermostat are good the control board is bad.

The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls.

Freezer is freezing fridge is warmer than usual does the dial indicating coldness from 1 to 2 apply to the freezer, refrigerator or both? have cleaned condenser on back of refrigerator - it was not really...

Usually, the freezer knob just adjusts the airflow from the freezer to the freshfood section. The refigerator control turns the unit on and controls temperature. When unit is running, do you hear the fan running in the freezer? The fan forces air to the refigerator section. If not, probably bad fan motor. If it is, do you see frost build up on the back wall of freezer section? If so this would indicate a defrost problem, ice build up on evaperator blocking airflow to refrigerator section. You cleaned the condenser, Was the condenser fan running? Defrost causes. Defrost thermostat, heater,defrost timer. Good luck.

I have a frigidaire freezer upright model#ffu20f9gw3

Without any additional info, there are a lot of possibilities:
1. Condenser coil (underneath unit) is dirty and clogged.
2. Compressor is failing. (need A/C tech)
3. Metering device is clogged. (need A/C tech)
4. Refrigerant charge is low. (need A/C tech)
5. Door seal is broken (frost will form around door).
6. Defrost heaters are stuck on (replace defrost timer located underneath unit at front).
7. Condenser fan has failed (underneath freezer on back).
8. Evaporator fan (inside fan) has failed (ice will form on cooling coil).

This should get you started...

If this helps you, please select YES to the first two ratings questions. Thank you, and Good Luck.

1999 Frigidaire Refrigerator

Check rear wall of freezer by feel for frost. Heavy, even frost indicates likely problem in the defrost system. Unplug unit. Defrost heater (in freezer behind rear wall panel), defrost thermostat (same area-must be checked at freezer temperature) or Defrost timer-located lower back outside of unit. Near compressor. Do continuity test on heater and defrost thermostat and if they show continuity (good), replace defrost timer. If not, replace the one that tests bad.

Defrost coils fully. Reassemble.

Please let me know if I have helped with comments and rating.

Refrigerator will work about 7-10 days after being defrosted until thick frost builds up again cutting off air flow to both compartments

Refigerator temp is rising Lower freezer compartment seems to be fine

Check rear wall of freezer by feel for frost. Frost indicates likely problem in the defrost system. Defrost heater (in freezer), defrost thermostat (in freezer) or 1 of Defrost timer or Defrost control (Circuit board) generally located in Refrigerator compartment but may be inside rear of outer case.

The bottom of my frigidaire is not cooling properly; and the freezer works great; is it a minor problem i can fix

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

Freezer cool but not freezing

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.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air
check defrost timer, defrost heater, defrost thermostat. In most newer models they don't have the timer but an electronic device which replaces the timer.

Refrigerator started getting warm, but the freezer is still cold? I have researched and found that it could be a defrost thermostat, defrost timer or defrost something else, but when I try to find these...

All frost-free refrigerator-freezers have a thing in the system called a Defrost Timer. The thing is a little clock of sorts that tracks accumulated running time. Every 8 hours of run time the thing cycles through a defrost cycle. The defrost cycle is necessitated by the humidity that forms ice crystals on the freezing coils, if the frost is not eradicated it can build up to the point where no air flows over the coils to chill the inside of the box. (it may keep the freezer cold but no air goes to the fridge part)The Defrost timer in all boxes fails eventually from old age. When that happens, the coils frost over until they become pretty much just a solid block of ice. Most timers are located on the front of the machine, behind that removable grille under the door. The timer has a round hollow shaft through it, and can be turned with a screwdriver. If the compressor is running, give the shaft a slow twist until a click is heard. The compressor will stop. Give the fridge an hour to defrost the coils, and check it to see if it took off running. If an hour has passed ans the fridge hasn't restarted, advance the timer again to start. Sometimes the nudge will make the timer run for a while. If this is the case, the unit will chill, and buy you some time to get it fixed. If the timer does not run, you can repeat the process daily until you get a replacement timer.

Heavy frosting of ice can seen inside freezer compartment panel

You have a defrost problem, either timer, heater, or limit. Turn unit off and defrost with a hair dryer.
Once you have done this get back to me and I will tell you how to test those items.
