I have a problem with no frost refrigerator of 1/5 hp, I had a moisture problem, a hair change and a 5/16 return tube but now it does not freeze in an evaporator and has a frosty return. What should I do? Reduce hair? The engine amp is 1.8 amp. Help please.

hello homorna, excuse me if I did not, evaporator has or degrees celcius and in the low pressure gauge it has 8 psi, my question is if reducing the capillary temperature drops in evaporator, the capillary is new for 1/5 compressor and the tube I put 5/16 back because I didn't have 1/4 the return has frost

The return with frost is to have more refrigerant, leave the pressure at 0 psi and measure the temperature give it working time hours.

Jorge the return tube is placed 1/4 never 5/16 (thick) and the quantity is minimum 1 meter and a half, if the refrigerator is medium, now you do not say which diameter or the amount you placed the capillary tube, It usually takes 0.31 and 3 meters, greetings

Thank you master Fermin for your comment, I decided to put it 5/16 for not having the smaller diameter 1/4, the capillary is new has 3 meters. It is a Frigidaire FRT093AG refrigerator of 255L freezer capacity is 65L uses 134a refrigerant. The problem started with evaporator sting, the sting was cured, compressor oil was changed, capillary due to obstruction and moisture, but it did not have the 1/4 tube for return. My question is can it work with that tube diameter or should I change it, thanks for your attention

Jorge once I did not get and I put that diameter and it was very difficult to control the equipment, since it is too big hehe, looking for a room, good according to experience lived by myself, greetings and luck.

Sorry, the diameter of the return tube is too large, look for a quarter, even if it is used, luck.

Thanks for your input, I will change the return by 1/4 tube and weld a liquid trap at the evaporator outlet to avoid more moisture, and put 2.5 meters of capillary.
I think your answer is the most successful, thanks
