Refrigerator running Time
Usually manual defrost refrigerators where the thermostat sensor was clamped to the freezer compartment and covered with ice, these refrigerators tended to have a very set running time. They would run for a while, and they'd be off for a long time, but once refrigerators had a thermostat sensor that sensed the air temperature in the refrigerator Refrigerators often had much longer running times.
So older, simple manual defrost refrigerators did not tend to run as long however they didn't often keep the refrigerator compartment as cold as you would have liked. The thermostat was sealed under a block of ice, so it was really just keeping that block of ice at a set temperature.
Once frost free refrigerators became common in the 60s everybody started complaining about how much refrigerators ran. I heard it from hundreds of customers.
