Attempted to duplicate fault hp is tripping on high head pressure after troubleshooting any and all possibilities narrowed it down to outdoor TXV metering device. High head pressure tripping quickly within 5-7 minutes of operation. Ordering part and will return when warehouse has acquired. Auxiliary heat is operational so they have heat while waiting on part acquisition. Entire balance paid in full.
