Can a burnt inverter AC outdoor PCB be repaired instead of buying a new one?

Yes, 95% of burnt inverter PCBs can be repaired by replacing the IGBT/IPM module and bridge rectifiers at 60-70% lower cost than buying a new board.

How long does the PCB testing and repair take in your lab?

Standard lab diagnostics and high-voltage bench testing takes 24 to 48 hours before safe courier return dispatch.

Do you provide a warranty on repaired inverter boards?

Yes, all repaired PCBs come with our 90-day replacement and repair warranty for complete peace of mind.

Component-Level Inverter AC PCB Motherboard Repair & Diagnostic Bench

Inverter Air Conditioner electronic control units are sensitive high-frequency systems combining microcontroller computing with 3-phase high-voltage power inverter bridges. When voltage fluctuations, lightning surges, or thermal breakdown occur, our ISO-calibrated electronics laboratory provides precise component-level micro-soldering rather than expensive board replacements.

Comprehensive Laboratory Diagnostics Process:

Optical & Thermal Imaging Inspection: Identifying micro-cracks in traces, swollen electrolytic capacitors, and shorted SMD resistors.
Oscilloscope Waveform Verification: Verifying PWM drive waveforms from the microcontroller to the 6-channel IGBT gate drivers.
IPM Module Replacement: Precision desoldering of blown Sanken, Mitsubishi, or Infineon Intelligent Power Modules using temperature-controlled soldering stations.
Dynamic Load Bench Run: Every board undergoes continuous run cycles connected to actual BLDC outdoor fan motors and rotary inverter compressors prior to dispatch.
