Anything below 60psig on your low side will have a saturation temp. lower then 32F, that's why your icing up.

Check that the underside of the evaporator is clean.
Could be undercharged, could have a metering device blockage or liquid line restriction. 

Would need to know your ambient temp, and indoor wet bulb, superheat and subcooling.

Here's a trobleshooting chart that might help,
