How to Troubleshoot & Replace Whirlpool AP6023677 / WPW10662129 Run Capacitor

I changed it out because of age.. 

New parts 

After viewing videos that explained each step of the troubleshooting and repair process I tested my system and order the start relay and capacitor for the repair. The procedure was simple and exactly as seen in the video. Unfortunately my problem persists and I have scheduled for a repair person to replace the compressor. My testing revealed a faulty capacitor but the compressor is also on the fritz. 

Installed capacitor... 

Talked with APP and they knew exactly what the clicking sound was and said to get it ordered as soon as possible because it would eventually fail and frig would not cool. Ordered the parts and sure enough by Sunday the frig quite cooling. Part arrive Monday, watched the video in the link and all done and fixed in about 10 mins. You guys are great. This is the 3 time I have used APP. Fixed my Maytag Dryer and replaced the fan motor on the same frig. Both are about 17 years old and better than any new appliance on the market. So grateful for their help and guidance and feel like I have a friend helping me. 

Called the help line. They suggested the start relay 

I could hear a clicking sound, the compressor starts and shuts down immediately. Replaced the start device and run capacitor Also cleaning out a lot of dust accumulating near the coils. 

Cleaned evaporator coils with brush and replaced digital control board........which did not solve the problem. The problem being the freezer was barely cold enough to freeze ice and the fridge was barely cool enough for food on the max settings! My thought was then turned to the start/run capacitor and relay for the compressor motor as the compressor was warm and no sound was heard as of running. I ordered the capacitor and relay and replaced them both and the fridge works like new again.....13 years old! For those not familiar with capacitors and relays.......they definitely do have a life span and will fail over time. The installation was simple.......unplug power, remove the back bottom panel, unplug the old cap/relay pair and replace with the new one. It is taking me longer to type this than it took to do the repair. The same thing applies to your air conditioning unit outside. Caps and relays do go bad over time. They are cheap to replace!.......and simple to install. bud 

Bought this part but the symptom went away. Exterior of the refrigerator is no longer extremely hot. I'm now seeing if the symptom returns. Will hang on to the part though. Determined that the condenser fan was working as it is less than a year old. 

Followed a video of the part replacement & replacement was relatively easy. (Removing the refrigerator from enclosed kitchen cabinetry & having clearance from kitchen island was, by far, the most difficult part of the project).
