Where are the coils located?
The coils are clean but there is a round piece of ice right above the coil assembly
Where Can I get the needed tool and materials to charge the system?
Is there a diagram that shows which is the high side and which is the low side?
I see where it says 5.25 oz R-134A
but it also says High side pressure 300 psi and lowside 140 psi. So I should use the piercing valve to bleed out the remaining pressure in the low side then add 5.25 oz of R-134? Should I use the kind that has leak stop in it?
So I should just be able to use a piercing valve and charging hose to add 5oz of R-134 to the low side and I should be good to go? Thank you Barry for the excellent service. If this works it will be the third successful repair I have been able to perform myself by asking an expert.
