How to Troubleshoot & Replace Frigidaire AP2592907 / 215846604 Refrigerator Defrost Timer

I removed to the cover to the coil, defrosted coil with a heat gun and checked the heater strip resistance. I set timer to defrost by hand to make sure everything was working. There was damage to the temp control sensor. Both parts were on your web site at a good price, ordering was easy. The parts were in the mail two days later. A screwdriver and nut driver were the only other tools other than a multi meter. Parts installed in five min. I had the option of talking with a pro !!! 

Appliance parts walked me through the diagnosis, to the correct fix. Replaced the defrost timer. Good fix......thanks a lot 

Troubleshot the problem with You Tube assistance and ordered the part from you folks. Parts have been swapped and refrigerator now working as it should. 

Several months ago, the freezer was so frosted, it blocked the air cavity that brought cold air to the refrigerator compartment. The result was the freezer was cold enough, but the refrigerator was near room temperature. At that time I defrosted it manually with the idea that that would correct the problem. It frosted up again. I defrosted it manually, then checked the schematic. There are three parts making up the defrost system: Timer, thermostat, and heater. I checked the heater with an ohm meter and got around 38 ohms. I concluded the heater was good. Then I bought the thermostat and timer from Appliance Parts Pros. The prices were good, and each part included a video showing how to replace the part. This was extremely helpful and easy to understand. I decided the problem was most-likely the timer and it was the easier thing to change since no wire splicing was involved. From the video, I knew exactly what to expect and what tools I needed. The change-out had no surprises other than that I learned there is access to turn the timer with a screw driver to cycle through all its steps. Doing this verified the timer was working and the defroster was now working. I did not replace the thermostat, since I could tell from the behavior of the heater that the thermostat was doing it job. The timer was an exact fit/drop in replacement. The whole replace operation took around 10 minutes, and that was because I was taking my time. 

I am a 71 year old woman and my husband is 76. Neither of us has training or experience in appliance repair. We viewed Youtube videos, then ordered one part from another site. They originally told us it was in stock, then had to backorder it. After two weeks, I found this site, ordered the part and cancelled the previous order. The part arrived as stated in good condition and it was easy to install. The refrigerator still didn't cool, so we went back to Youtube videos and diagnoses a second problem. Order a second part from this site and it was delivered as stated on time. That fixed the problem and we now have a working refrigerator. Thanks to your help, we were able to do what two appliance repairmen could not. It is very easy to use this site and customer service helpful and efficient. I will never go back to the other site, which some Youtube videos recommend. I might even have bought a new refrigerator (even though mine is only 7 years old) except most have to be backordered now due to shortages. I cannot say enough good things about Appliancepartspros. You helped my husband and me, complete novices, through a successful repair. Thank you! 

After 10 years, the Start Device Part # AP4393517, attached to the compressor failed. I replaced it with the similar part, but not factory original and not sure if it is new from an appliance store nearby. By not being sure how long this part will last, I decided to order this part and the other parts from you, just to be on the safe side. I replaced the part myself. It was not easy to get down to the floor and a little cumbersome to remove the part because it is attached very hard to the compressor. 

I replaced the timer and now it's working fine. 

I WATCHED THE REPAIR ON GOGGLE ! I REPLACED THE THERMOSTAT AND THE DEFROST TIMER. $40.00 WITH SHIPPING ON MY DOWNSTAIRS FRIDGE . EASY TO DO ! MONEY WELL SPENT.
