Product review (5 stars): Easy Fix
The start kit is a simple fix for one of the most common residential refrigeration problems on units in the 10 - 15 year age range - the "hum & click" symptom.
This kit is relatively easy to install, comes with all the parts you should need short of a zip tie, and most average DIYers can probably accomplish its replacement. The parts are likely different from the ones to be replaced and some wiring may be involved for grounding. This product is the same one that a professional would charge you hundreds of dollars to diagnose and then install. Warning: The instructions are not intended for a tutorial on replacing the device. You can find video and instructables online to help you prep and guide you through - proceed with caution.
There are hazards to both you and the refrigeration system so proceed with that in mind and with due caution. Experience or the ability to remove and replace in a orderly and documented way will get you through the process. Again, this is the same part the pro would use but, he has experience so he shouldn't need instructions.
Are you experiencing a refrigerator that cycles on and off, running for a short period and shutting off, maybe clicking several time before starting again??? It is a common problem for those systems that are 10+ years old. This may be all you need to solve your refrigeration problem. It is a good cost effective first step to getting your refrigerator up and running again for anyone who is average in DIY skills and wants to take a shot at saving some money. A compressor or refrigerator replacement isn't cheap and a bad technician with a bad diagnosis can lead to one or the other.
