Electrical & Component Fault Diagnosis
Expert diagnosis and repair of AC PCB, capacitor, compressor, and electrical faults.
About This Service
Modern air conditioners contain sophisticated electronics including PCBs (printed circuit boards), capacitors, sensors, relays, and control modules. Electrical faults can cause an AC to stop working entirely, behave erratically, or display error codes. Altaf Khan has experience diagnosing and repairing AC electrical and component faults across Mumbai and Maharashtra.

Frequently Asked Questions
Switch off the AC and do not keep trying. Repeated trips can damage the compressor. Call a technician to diagnose — common causes include a failed capacitor or shorted compressor winding.
Sometimes yes — individual components on a PCB can be replaced. In other cases, a replacement board may be more cost-effective. We assess and advise honestly.
No. Intermittent electrical faults can indicate a developing serious fault. We recommend having it inspected before continuing to use it.
