Regular readers of this blog will remember that whenever possible, we advocate using OEM parts from the appliances manufacturer. Even though the parts we are describing today are "universal", our intent is that these be used in places where the manufacturers OEM is no longer available.
For years, the common data logger was a large device, about the size of shoebox that had round paper discs with a graph that rotated. As the graph rotated pens marked the temp and time settings of the various stages of the refrigeration cycle.
Technology has greatly improved temperature data logging. These days the Supco data logger, part SL300T is a great solution. Much smaller than the old style of loggers, this unit is little more than a sensor. It is somewhere in size between a Zippo lighter and a cassette tape. The idea being you can leave the unit behind to take more detailed reading than the larger old mechanical loggers.
When you are ready to analyze the data, Simply plug the unit into the USB port on your computer. Using the included software a variety of analysis can be applied to the data, taking the guesswork out of refrigerator diagnostics.
Designed for freezer installation, the SC1002 is good for a range of -6°F to 39°F (-21°C to 4°C). It is intended for temporary usage and can be mounted via suction cup, Velcro or screw mounts.
|URCO410 & URCO810|
The long standing favorite hard start was the 3-in-1 RCO series from Supco. As newer refrigerators do not always have a start capacitor, Supco introduced a new line of starters that can be used on machine with AND without start capacitors. For 1/4-1/3 HP compressors use URCO410. Smaller compressors in the 1/12th-1/5th HP range can use the URCO810.
Still, a lot of older refrigerators have timer failures. When you just can't get the original timer, the Supco UET120 universal defrost timer is a good fit. It is an electronic timer that can be programmed for the most common defrost settings and plugs in like a traditional manual timer. This is an item every servicer should keep on hand.
