Checked in with the MOD and was shown to the unit. I found that the condenser fan was running, the evaporator fan was also running and the evaporator was clear of ice. The compressor was drawing lock rotor amperage and the compressor at a bare minimum, needs to be replaced. The unit itself is very old and has already been retrofitted with R409a from R12. Even if the compressor replacement is approved, replacing the entire unit should be considered. Call is complete.
