I ordered a defrost timer and defrost thermostat from partselect.com. Parts arrived in 2 days (earlier than expected). Unplugged appliance, removed bottom cover, unscrewed 2 screws holding timer in place, unplugged timer and replaced with new part. Fastened back into place. Next removed back cover of freezer (5 screws using nut driver). Disconnected old thermostat and removed. Wires already had connectors installed. cut off the connectors with some wire left on and reconnected them to the new thermostat with the included blue wire crimps. Tried to use the shrink tube to insulate but couldn't get it snug enough. Just used electrical tape instead. Reinstalled thermostat. Reassembled cover. Plugged in and fridge and freezer are working fine again. Thanks partselect.com.

Popped off the front plastic cover on the bottom of the fridge, under the doors. Two screws held the defrost timer on under the front side of fridge (below freezer door). You can't really see the timer except for the adjustment knob that is accessible through a hole. Once the screws are removed, disconnect the wire plug and remove and replaced unit. Works fine ever since.
This fridge is less than 2 years old really disappointed with frigidaire quality. Had a appliance repair guy diagnose the problem and paid $45 for the service call but decline for him to do the repair for $320. Remove the cover 4 screws holding it on top of fridge the defrost timer is inside 2 screws and you just unplug and replace with a new one. The defrost thermostat is in the freezer compartment, remove the ice maker if equiped then remove back cover, cut out the old thermostat n crimp in the new one. So far the fridge is working but still not getting as cold as before but good enough to keep things safe. Thanks to partselect.com i saved a bunch of money doing it myself.
Make sure unplugged the frig before doing any repair. Just like other DIYers. opened up the evaporator located inside the freezer. Replaced the defrost thermostat, there's only 2 wires, so just make sure which is positive, which is negative. Replaced the defrost timer located on the bottom front of the frig. There's on 2 screws to unscrew. All those work took me less than half hour. Turn on the frig., now it works like a champ again. Hope it will last another 10 years.
There are 3 parts that actually control cooling cycle: Temperature Thermostat, Defrost Timer and sensor/relay on the back side of the appliance. If fridge cycles up after you turn small knob on defrost time (you'll hear click, problem lies between first two components.Replacing them is really easy. Make sure you handle thermostat wire carefully. Check for connectors holding firm.Use schematic diagrams you may find at this site.Good luck.
Removed the temperature control dial,took out the 3 screws that hold the cover for the thermostat and defrost timer, disconnected both the defrost timer and thermostat and replaced with new items. The refrigerator temperature has now been staple for one week.
I put the refrigerator and saw that the fan wasn't working so I change the fan and the problem still the same. I order a timer and thermostat and change them, nothing change so I order the capacitor and when I remove it I saw that the relay swith was burn out so I order a switch and evarything is ok.The problem when the fan broke the compressor overheat and burn the swich.I learn a lot and still saving money over these repair guy.Thanks
removed back cover from freezer to replace defrost stat. removed cover from refrigerator to replace defrost timer
I secured the power to the fridge. I took the metal panel which covers the cooling coils in the freezer off by removing the the 6 sheet metal screws. I used a standard hair dryer to melt the ice block which had formed due to the failure of the defrost timer. I replace the defrost timer, which was located behind the left front wheel of the unit. Finding the timer was the hardest part of the job. Since I was having trouble with the defrost cycle I also decided to replace the defrost thermostat due to its age. The most important item I would like to share is once all the work is done and the panel is back in the freezer, the power is restored take a straight slot screw driver and give the defrost timer about an eighth of a turn clockwise to ensure it starts. Then mark it with a sharpe and check it in 3 or 4 hours to make sure it is running. I did not do this on the one I installed and the freezer did not go into the defrost cycle. Once I got the timer started, well the ice cream stay frozen. BE SURE NOT TO WORK ON YOUR EQUIPMENT WITH IT PLUGGED INTO POWER SOURCE!!!Jim
removed ice maker,,and screws holding back of freezer cover,unplugged wires and removed the cover and fan.wow,only wire to element had come unplugged!went ahead and replaced thermostat,and defrost timer,both were easy to do
The defrost timer is located under the freezer side behind the lower plastic cover. Very simple, just 2 screws and a plug, and your done.The thermostat requires removing the lower drawers in the freezer and unscrew the back side of the rails and let them hang over to get access to the lower cover on the back of the freezer. Once the panel is off you will be able to see the thermostat. From there you just remove the thermostat from the clip, cut the 2 wires, splice in the new thermostat and re install using the new clip and your done!!This was my first time and it was really simple. I had a local repair shop quote me $375.00 . I did it myself for under 50.00 shipped to my door..
Replaced both the thermostat and defrost timer and still froze up and still warm air to the fridge, turned out to be the defrost heater coil. It was cracked in the middle, very easy to test with a multimeter. Replaced the heater coil and all is like new!
Removed the housing with the light, 4 hexhead screws. This exposed the defrost timer, removed 2 hexhead screws, electrical connector and reassembled the unit.Great resource and service, thank you.
First I removed the plastic grill (pulled out, no screws) from bottom of refrigerator, then I removed electrical plug & two screws from old timer (timer located on the front inside left lower side of refrigerator). Installed in reverse order.
First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the wiring harness plug, replaced the old timer with the new one, re-connected the wiring harness and reinstalled the mount in position. Hardest thing about it was lying on the floor.
