Does removing every third fin on the cooling coil in the refrigerator help the frig get colder or does it keep it from getting too cold?
Hi, Removing fins will slow down the dispersion of heat. The more fin ‘area’ the better the cooling release. The fridge will take longer to cool, therefore it will run for longer trying to get the temperature down. Smarter people than us have worked out the amount of fin cooling area necessary for the efficient operation of a fridge.
The removal of the fins to the evap is 1 step of a repair bulletin LG posted. All French door w/duel evap models that have complaints of water under bins, fresh food section not cold enough, or, veges freezing are to perform repairs per LGs bulletin. In a nutshell, the evap was freezing up, the drain line would freeze, thus, improper air flow over evap coils = not cold enough complaint. Drain froze so water builds up under crisper. LGs fix included a new damper, seals, defrost controls, fin removal & pcb replaced. New pcb has extended defrost time. A lot of work, only to return in 2 wks w/same issue. The frost pattern on evap was heavy across the top an thinned closer to the bottom. I think LG thought it was an airflow design flaw & was redesign it in the field. I found that if you i increased defrost time by moving the defrost sensor away from the heater a little, then attach a drain clip to heater and insert in drain -problem solved! No returns, no expensive parts and it’s quick n easy.
