Robin for Model Number LFFH21F7HWJ We have changed the Defrost Thermostat two times although my husband doesn't think that is the problem but we do defrost it each time we replaced it. It runs great for a few months then it gets frosted back up and the temperature goes back above zero and it has frost on the coils again we tested the defroster element last time we replace the Thermostat and now the temp is back up and something needs to be done but it runs great after it is defrosted. Any ideas?
