Frigidaire 5303918202 Defrost Thermostat OEM Part

This was a 2000 model so rather than just replace the defrost timer which was visibly burnt on the terminals, we just did everything. The cold control, defrost timer, thermostat, defrost heater and the compressor capacitor were all replaced. I had the same issue on my older unit and tore it apart replacing one item at a time over a three month period so on an older one i suggest do it all while it is apart.

Not sure as to which was bad but for less than $40.00 dollars for the parts and about 30 minutes of my time I was able to replace them both. I watched both how to videos and they explained everything thoroughly and completely. I ordered the parts on Monday got them shipped to my door on Wednesday afternoon and within 45 minutes after I got them my freezer was backup and running. All for much less than the price of a service call would have been. Appliance Parts Rocks!!! In my book.

Removed the panel at back of freezer, found that the evaporator coils were completely iced over. Removed the connectors at the of the defrost heating element, it was OK, had continuity. Decided that the problem was either the defrost thermostat or defrost timer. Ordered both parts, as they are cheap and testing the thermostat can be difficult. Also, used a hair dryer to defrost the evaporator, which allowed the refrigerator to start cooling both sections, at least for a few days, until new parts arrive. It will work until the evaporator coils frost up again. When installing the defrost thermostat, I soldered the connections and covered with shrink tubing and put silicone at the ends. New parts arrived and replaced both parts and refrigerator is working.

I decided to order a defrost timer, a defrost thermostat and a start relay. I thought for the fifty bucks for everything why not give it a shot. I first installed the defrost timer (all of 7minutes) then the defrost thermostat (about the same except I didn't use the crimp connectors or heat shrinks and just used wire nuts instead.) It turned out that the compressor in this unit does not have a removable start relay so I couldn't use that part. Then I took a portable air tank and just blew out all the dust and dirt from the coils and cleaned it well everywhere I could. Then plugged it in and it works perfectly! It actually works better than when I first purchased it new, I always suspected something was wrong back then. It was so easy to fix with the videos and since I didn't use the start relay it really only cost about $30 dollars total to repair. Love Appliance Parts Pros!
