I am going to attempt another try to get my AB cold machine with AB power plate working properly again. I had a lot of advise on old thread back in March. Some conflicting advise at that time. purged some refrigerant at that time with no success in the end.
is in the Bahamas
so I am limited on qualified help at my specific location.
I will be bringing new Gauge set, pump
, adapters, scale to weight refrigerant, Etc.
I plan to check for leaks
done system for several hours then put in 3.2 OZ by weight. I don't feel confident trying to replace the filter/dryer because it is soldered in place so keeping my fingers crossed it will be OK.
I will only have a few days to do this job along with many other tasks to prepare boat
season so I would like to be as efficient with this attempt as possible.
detailed step by step directions would be appreciated
Last attempt replaced controller, put jumper on T-stat, Installed new 10 Gauge wire with fuse directly from battery
, bypassed AB stainless steel
board at control module, replaced 12 volt fan. There are no code lights flashing on LED added to controller. compressor
and fan stay on and power plate gets cool and condensation
but no frost or significant cooling
. Therefore I think I have ruled out electrical
supply, controller, T-stat issues. Think we are dealing with refrigerant issue.
