After two 100 degree days in a row the refrigerator temperature was sitting at 50 degrees and would not return to normal during the overnight periods. A digital thermometer in the freezer showed a temperatue of 22 degrees. So freezer working and refrigerator not. Technician ran some tests and everything appeared normal - so he suspected the boiler. Then we spotted it, a pinhole leak in the plastic water line to the ice maker was spraying water on to the heating element. Our conclusion - you wouldn't see the water leak because the heating element was evaporating the water. The water was cooling the heating process so the ammonia rising in the system was not as hot as normal. Transfered heat to the freezer allowing it to run at a normal temperature but not enought heat transfer for the refrigerator thus its abnormal temperature.
Water has been off to the ice maker for 24 hours and the refrigerator temperature is 34 degrees. The pin hole leak was a result of the plastic line running to close to the metal burner enclosure and chaffing the line. This will be an easy to fix but it is just another one of those annoying water leaks I have been experiencing for the past year - at least it wasn't in the basement this time.
