I have a GE side by side refrigerator TFX27F year 1987. We have changed motor because it wasn't cooling. It worked well for a few days and after that the temperature dropped. We have replenished with freon, it worked for 24-30 hrs and again the same with the temperature. It loses freon. Any suggestions? The refrigerator specialist that came found and fixed a couple of leaks but again the problem exists. Please help. e-mail jsjoannides@yahoo.co.uk Thanks
