Question about Goodman PHKJ048-1 Air Conditioner
It seems to me that your suction should be @ 76 or so. 52 is low. the coil will ice up with any suction PSI below 58. Disconnect the unit from the duct work and make sure there is no restriction in the duct size. In other words. Does the unit work properly with out the duct? I find most mobil homes have a restriction in the amount of return. A 5 ton split needs a 20 inch round return. You never see this size return on a package unit. Does the return **** the filter in? I have had to add returns to large mobil homes because there just not designed right.
this is only a possibility. Is the temperature split on the equipment between 18 and 20 If it is then I don't thing you have an equipment problem. Also make sure there are no holes in the duct work.Last one I had unit was working fine but the duct work had a big hole in it from some animal under the trailer.
