Upon arrival found unit with error code 98/99. Compressor debate, lockout. Checked over system, no airflow or static issues. Coils are clean. Pressures in warmup are 120/300. Once warmup cycle ends, compressor derates and then shuts off. Spoke with carrier tech support. Ran several tests on system, found the inverter has internally failed. Not allowing proper function of unit. Need office to complete estimate for replacement inverter, and return to replace once part comes in.
