Hello friends I went to see this refrigerator and had the burner compressor burned, I proceeded to see the broken compressor plate and said this: Embraco PW 5.5K 11W, 11.5 / 11LRA, R12, 1PH, ask in a refrigeration house and replacement What I got is the Embraco EMI 55 ER, 10.4 / 10.2 LRA, blends, 1 PH. Now, as the replacement did not bring oil cooling, I added that pipe to continue the circuit. clean the circuit and change the molecular filter, empty x 1 1/2 hour and proceed to charge MP39 gas, the condenser gained temperature quickly, but the temp inside the frezer only reached 17 ° C above zero with a gauge pressure of 3 pounds. I can't get the temp down. Now my question is, is it the right replacement compressor? Do I have to do the gas charge in a liquid phase? Or can I have some other problem? Thank you to anyone who can guide me to give me a solution

Hello, increase the pressure down and monitor the result by monitoring the amperage, greetings.

It is charged as a liquid this refrigerant works with pressures of 4 to 8 psi luck

Hello friends, perform the system empty again and load MP39 in liquid phase and slowly, it takes me a whole day to work between 2 to 4 psi and a small return of ice in the aspiration that eliminates it by purging at small intervals, all this I did it with a live compressor (without going through a thermostat) and achieved a maximum temperature of - 27 ° C, measured in the frezer environment. Then connect everything again but through the thermostat and place the probe where the tip of the thermostat tube is fixed, reaching the same temperature (-27 ° C) and in the middle position (N ° 4) it never gets to cut, just He did it once by taking the thermostat wheel to a minimum and then leaving it at 3 and still uncut (scale 1 a7). Now I have doubts if the thermostat is bad or would have to reach a lower temperature, I have arrived in other frezer at - 31 ° C, where the thermostats need to reach those values to make the disconnection. Thanks to the data previously provided I could get to charge the refrigerant, if someone can throw me a hint I would appreciate it

Hello, if it is the minimum temperature you can get then regulate the thermostat at an intermediate point between 1 and 3, it can be 1.5.2, or 2.5 and you can get it to make and make the cuts now, if you manage to lower the required temperature, by Welcome thermostat, regards.

Well folks, I can't hit the spot; As I said before I could have a good cold. Now every time I try I get to -22 ° C and the thermostat doesn't cut. I decided to squirt R22 to see if it cut and it didn't. I calculated that it is the thermostat and take it out, the thermostat is a Ranco K54 - L 1819., I proceeded to test it and place it loose in the environment in a freezer no frost along with the temperature probe and it reached -22 ° C and short. The subject that performs the same test on the frezzer that I am repairing and reached 23 ° C and does not cut. I found some information that I put down

It gives me a disconnection of -32 ° C, will it have to come to that? This frezeer reached a max of -27 and having ice return to the compressor, that is, more than that I will not be able to get it out. Can I regulate the thermostat? It has a single screw between the contacts and that is inserted inwards. On that would have to act? How?? I would appreciate guidance since my papers burned

Well, I was looking to propose a solution to close the post but I didn't find the way. I also comment the solution. I decided to change the thermostat by doubts that it is uncalibrated and after doing so the frezzer came to cut with an inetrmediate position on the dial, keeping the temperature between -19 to -22. Thank you all for your help
