Inverter AC PCB Repair & Precision R32 Gas Charge in Sayajigunj, Vadodara

1. On-Site Symptom & Failure Diagnosis

Partially restricted capillary strainer combined with undercharge caused compressor overheating and outdoor IPM fault. Upon arrival in Sayajigunj, Vadodara, our mobile engineering squad recorded baseline electrical amperage, voltage stability, manifold operating pressures, and airflow Delta-T before opening any enclosure or refrigeration joint.

2. Engineering Rectification Executed

Flushed liquid line with dry nitrogen, replaced strainer, repaired IPM gate-drive resistor network on outdoor board, evacuated to 450 microns, and weighed in factory R32 specification — achieving 8.8°C grill air.
