This was the second part I tried. The defrost timer was first, but that did not fix it. To do this I had to remove the ice maker and the back plate of the freezer. Then I defrosted the coil and cut the wires. stripped them back and installed the new thermostat. re-assembled and tested. has been working great ever since.

This was extremely easy. Took off the control box (housing that covers the light bulb, has the temp control dial on it) and easily replaced the defrost timer. Then, emptied freezer, took off cover at the back of the freezer. Disconnected old defrost thermostat, attached new one, reattached back cover, melted accumulated ice, put stuff back in. Started up. Been running great ever since. No more ice accumulation in freezer. Temp stays constant. Great service from PartSelect, saved lots of money. This job is easy on this fridge, go for it!

Broke a blade off of the fan

When cleaning the coils on your refrigerator always remember rule number 1, unplug it first. I was cleaning the coils and hit the fan blade while it was moving with a brush, thus breaking off one of the fan blades. I ordered a new fan and installed it in about 15 minutes. Very easy repair.

Freezer cold. Fridge too warm.

  • Customer: Marc from Sumas WA
  • Difficulty: Easy
  • Time to Complete: 1- 2 hours

Ice build up to back of freezer. Fridge way too warm for preserving food/drinks. Unplugged fridge and de-thaw freezer with a hair dryer. Removed and replaced defrost timer in the fridge area which simply unscrews and plugs in. The video supplied by PartSelect worked well for this.

The Defrost Thermostat required a bit more work as it is accessed through the freezer compartment. I had to remove two screws to get the back cover that houses the fan removed. Then you cut the wires from the old Thermostat and remove it before splicing in the new Defrost Thermostat using the supplied crimps and matching the wire colors. It is useful to have a good wire stripper/crimper ready to make the job simple (I bought a pro one for $28 at Home Depot but they can be found cheaper). Also, there is a bit of heat shrink material included to protect the wires from moisture so a heat-gun will do the trick or Good quality electricians tape will also cut it.

I then sparked it up and it works as new. :)

The evaporator coil in the freezer would cake up with ice, choking off the cold air flow into the lower refridgerator compartment. A repair man had previously replaced the defrost heater element, but this did not fix the problem.

First, unplug the refrigerator since you're working with live wires.

Remove the 4 Philips sheet metal screws holding the plastic housing that holds the temperature control to the top of the refrigerator compartment. Pull the housing down then out since there is a tube on the housing where the water flows out the back of the refrigerator during the defrost cycle.

Remove the 2 Philips screws holding the defrost timer on the plastic housing. Pull the connectors off the old timer and attach them in exactly the same positions on the new defrost timer.

Attach the new defrost timer to the plastic housing with the 2 screws.

Reinstall the plastic housing, making sure the water tube is inserted into the back of the refrigerator wall.

Plug the refrigerator back in and you're done.

Support rails holding meat tray drawer broke.

I removed the drawer from the support rails and placed it aside. I then removed the entire shelf that the rails were attached to. Each rail contained one (1) screw. I removed the screw, slid the support rails back approximately a 1/4 inch and they popped out. I replaced with the new rails, sliding them into place in reverse of how I removed the damaged ones & attached with the screw. I cleaned the shelf off and placed it back in the refrigerator, and placed the meat drawer onto the new rails. It actually took longer to clean the shelf than perform the repair.

Side-by-side .. freezer working, fridge not cooling

My freezer was frozen but my refrigerated side was not cooling, the temp was actually around 60-degrees. After inspecting i noticed no air was flowing through the vent from freezer side to fridge side. I removed everything from freezer and took the back wall panel off inside freezer section and immedietely noticed alot of ice on coils etc. After researching i found the defrost timer was not working and thus allowing frost and ice to build up on coils and block air flow. My defrost timer was located on the front bottom left behind kick panel, using a phillips screwdriver i removed 2 screws and then disconnected wire harness to the defrost timer. Then i inserted new defrost timer and connected wire harness and then put the 2 screws back in. My fridge is now working great and the ice build-up is gone and i am getting good air flow .. temps on fridge side are now between 32-34degrees. This was an easy project and saved me alot of money doing myself

I simply snapped in the new part. It took a few seconds. I would like to say that I found the part using the model number of the fridge. When I went to look at the description it said the part was 26 inches. The one I had was only 24 3/4 inches. I called you guys and was told that this was the correct part and to ignore the measuement.
You were Right! the part fitted perfectly.

Refrigerator wouldn't defrost

  • Customer: Patrick from Gansevoort NY
  • Difficulty: A Bit Difficult

First, I replaced the defrost timer, really easy, 4 screws popped the cover of the electronic area (top of refrigerator compartment) took it out and plugged in the new time. Unit still would not defrost, so replaced the thermostat as well. Bit harder, removed ice maker, 2 screws, back plate from freezer, 4 screws. Thermostat was clamped to a copper tube- the original had one of the wires hanging out of it- cut the wires and crimped the new wires on, shrunk the plastic tube with blow dryer over the wires (taped them for good measure) and so far so good. Learned most of this through these tips, so keep reading if this isn't your problem, just save myself $1000 on a new refrifgerator...

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.
