I have a quite expensive fridge ($4k+) that is over 16 years old and the compressor was overcurrenting to the point of cycling the protection. Thys may have lead to oil moving about and possibly choking system so I am unsure if the compressor is just working hard and there's a partial obstruction or if it needs replacing. Using thermal camera I can see that with a vacuumed down dry system having correct charge of 47 grams R600a it is still at 1.3 amps (should be 0.6 with trip at 1.08) and the cooling is it fits, bursts and hisses. Barely making it down the large evaporator before the protection trips after 2-3 minutes. I tried looking for any thermal gradients that are not supposed to be there assuming for example a obstruction in the drier-filter or capillary somewhere but I see none. Capillary is coaxially fed from compressor all the way up to top of fridge and evaporator so that section can not be examined easily. (This is a cooler/refrigerator only design, no freezer, designed for 6-18c cooling internally only.) I am tempted to tap into the high pressure side to look at the pressures during running to determine if the compressor is just working hard or if it is just running hard. The heat build up in the condenser is quite low and the low side almost develops a vacuum but goes back up to a few psi before the OLP triggers making me wonder. I have a high rez thermal video available of the evaporator as well as the compressor/capillary/condenser if of interest.

After 6 years I would like to ask if this good to discover the gas leakage in cars referegirant
Hello, please try.
