Product review (5 stars): and getting worse daily. Since there is no thermometer in either ...
We were ready to buy a new refrigerator. but saved $2,200.00 by installing this COMPRESSOR START RELAY.

Symptoms:
1. Our eight year old Jenn-Air with French doors with freezer on the bottom, was not holding food properly for the last few weeks, and getting worse daily.  Since there is no thermometer in either the 'fridge section or the freezer section, we bought a couple of simple thermometers from Amazon.  These show current temperature and also record the high and low temperature.  These verified that the internal temperatures were not what was set or desired.
2. My wife was noticing frost - not ice - on many of the frozen items,  Ice cream was soft.
3. Used a flashlight to look under the refrigerator in order to view the condenser coils for this model.  Many models, especially those with the freezer on the top will have the condenser coils on the back,, probably exposed.  Over time dust will accumulate on these coils.  This can interfere with the condenser operation and make the compressor work harder. Ours were covered in dust, had to use both vacuum and high pressure air to clean (only two inches of space under this model refrigerator).
4. Once the refrigerator was moved out from the wall, I could hear a clicking about every two or three minutes.  The sound was coming from the compressor which we had exposed by removing the rear cover panel.
5.  That clicking sound is the compressor starting then stopping and restarting every few minutes.  You may have heard this in your car's air conditioning system and is known as "short cycling".  Short cycling can be an indication of low Freon caused by a leak in the system or an iced up condition on the evaporator coils.  However, there are other items that can create the same symptom; bad control panel, bad compressor starting capacitor or the COMPRESSOR START RELAY.  The relay used by Jenn-Air, Maytag, Whirlpool and just about every other manufacturer have a reputation for failure.
6. As much as I hate R&R (remove and replace) repairs, it is difficult to check the relay and replacement is easy and inexpensive.

Repair:
1. Very easy to replace the COMPRESSOR START RELAY.  Plug and play unit,  unplug the refrigerator.  remove wiring harness clip, remove COMPRESSOR START RELAY.  The capacitor is attached to the COMPRESSOR START RELAY and can be removed and installed on the new COMPRESSOR START RELAY, (the capacitor can also cause the symptoms if it is bad, so you might want to replace it as well).
2. Reinstall the COMPRESSOR START RELAY, cover panel and you are done.
