Well the title about says it all. We often don’t realize how much heat is put off by the typical incandescent light bulb, especially when they are inside of a cool refrigerator. But then we run across a unit like the one pictured above, and one look says it all. This is a rather unconventional situation where the unit was installed during construction so the condo was unoccupied, the compressor was never turned on, but because the door switch was not working properly, well you can see the results. The reason I bring this up is not only because it’s cool to look at, but to get you thinking. Yes, you, the professional technician looking for the reason the customers fresh food section isn’t as cold as it should be and you have checked and replaced everything you think could be causing the problem. I know it’s rare, but if a light bulb or two were to remain on while the doors were closed, well the result could be that higher than normal temperature the customer is experiencing.
