As professional Appliantologists, we’ve all run into situations where we realized that we needed a way to log temperature data inside a refrigerator for at least 24 hours to get a clear picture of what’s going on inside that box. A couple of examples of situations like this are:
Customer complains of warm temperatures in the beer compartment of her Maytag side-by-side refrigerator but says that the freezer compartment is fine (and we know how accurate customer temperature measurements are… NOT!). You arrive and measure the freezer temperature using your infrared temperature gun and get readings that vary from +5F to +12F. Marginal temperatures for a freezer, but was that because it was just coming out of a defrost or off-cycle? Was the door recently opened just before you got there? You don’t know and all you have is the one data point: the measurement you just made. Wouldn’t it help your diagnosis if you could put a data logger inside the freezer for a day or so and then look at a graph of the actual temperature measurements inside that freezer over time?
