Hi there, thanks so much for the replies. I had a "Oooh so that's how it goes" moment
The refrigerator is an LG GC-269VL
and the airconditioner is a 0.75hp Carrier..i forgot the exact model..
I'll go have a look-see on the locally distributed knockoffs and see if they're affordable..well they'll be most probably made in China so they will be cheap...reliability and accuracy is still a question though
