Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Can you see the motors (compressors} if so what refrigerant are they using R134a or R600a ?
Secondly when you switch them both on can you see, hear & feel these motors running?
OK you will see that there are three pipes connected to the motor, one is small, one is larger and one is crimped off, can you see these?
You are I have just asked you a question see above your comment
I have moved this across to a question and answer session so that we can work one to one, can you see the three pipes connected to the motor, one small, one slightly larger and one crimped off??
OK that is fine, when You or a friend can get the thing open come back to me and we can take it a step at a time, As we are now in question and answer mode there is no extra charge or time limit. Ian
