replacing a coil sensing thermostat on a cooler with an air sensing thermostat is not a good idea

Had a situation where somebody changed a coil sensing thermostat with a regular temp control and a couple of days later the coil was iced up. We need to keep in mind that the coil sensing thermostat also acts as a defrost timer or so to speak. It senses the colder than usual evaporator temp and shuts off the compressor regardless of cabinet temperature. If you must install the air temperature stat for more than a couple of days or plan on leaving it that way you need to install a defrost timer. Has anybody else ran into this problem
