Adding a heater is negating the whole concept of the goal of sub cooling the refrigerant and rejecting heat from it! might as well choke off the condensor rather then add a heater, same effect!

If it is freezing up there is an fundimental issue with the unit or the design of the unit that must be rectified properly! Does it take more work and thought and time? Yes but once resolved it is truely fixed, and equipment life will be better for it and the quality of repair superior!

In the time of low cost garbage, incompitant & half assed repairs (due to under-trained & overloaded techs) and throw away products, taking some time to do a therough and solid repair doesn't go un-noticed

Just some personal thoughts and observations.
