Often, liquid refrigerant will accumulate in the bottom of the condenser and receiver, and condenser subcooling readings will be normal to high because of this. Condensers are subject to clogs because of the leftover particles in the refrigerant. The TXV is not seeing normal pressures and may even be trying to pass liquid and vapor from the starved liquid line. Most of the refrigerant will then be stored in the condenser and receiver, simulating a pumped-down refrigeration system. To determine if the problem is a partially restricted filter drier, follow the checklist below: Assume that this R-134a refrigeration system is a TXV/receiver system employing a filter drier and sight glass. Typically, the AC condenser fan cools the condenser when you start your engine, but if too much heat is built up by a lousy condenser, then the Fans wont be enough cooling. symptoms of undersized condenser.
