We bought a new refrigerator last summer (it had been on order for 6 months). Nothing special---just a regular old domestic side by side refrigerator/freezer.
It hasn't been a good experience---it can't make enough ice to supply my wife and me----plus it has temperature control problems. We had the authorized factory service dude show up and immediately diagnosed the problem as a defective ice maker! That took 2 minutes and he told my wife they would ship a new one and when it arrived to call them again and he would come and install it. Well---that took about three weeks and he came and installed the new ice maker.
I "missed" him on his first visit but was here for the replay. I suggested to him that the ice maker was only a symptom and not the root cause of the problem----he knew better. I offered to show him a series of pictures of the thermometers I had installed in both the refrigerator and the freezer---he wasn't interested. He told me if I wasn't using a digital IR non-contact laser temperature gun I was only wasting my time. He even took his out and took a few shots---I guess to make me envious. I did notice that his laser gun was showing the same temperature that my dial thermometers showed---but I didn't belabor the point.
Further to that introduction to thermodynamics he proceeded to lecture me on the finer points of the refrigerator---it sounded like a training tape in replay
So----now they are coming back because it seems the new ice maker has the same problem making ice as the original one had---imagine that
But this time I am lying in wait. I have upped my game----for $35
And it is cool----no pun intended I have a unit in the refrigerator and another in the freezer. I installed them today. There was nothing to set them up (I had to pick F or C) and downloaded the APP on my phone. The first one paired to my phone in the common Bluetooth method without any issue and the second one climbed on board all by itself.
So, now I am recording temperature and humidity in both sides, 24 hours a day and graphing the results.
With about 10 hours of monitoring and the refrigerator set at the "Ideal" setting the refrigerator has varied from a low of 30.2 to a high of 37.0 and the freezer from -6.0 to +12.0
I can't wait
