InverterACPCB Comprehensive 90-Day Warranty Policy
Our industry-leading Warranty Policy guarantees performance and reliability for every repaired and replacement Inverter AC PCB, refrigerator motherboard, and electronic control card delivered across India.
1. 90-Day Standard Lab Warranty Coverage
Every electronic board repaired in our laboratory or purchased as a tested replacement from our catalog is covered by our full 90-Day Warranty Policy. This warranty commences from the date of confirmed delivery by our courier partner.
2. What Is Covered Under Warranty
Our warranty guarantees complete protection against component defects and workmanship faults under normal operating conditions:
- Semiconductors & Power Stages: Replaced Intelligent Power Modules (IPM), IGBT bridge rectifiers, and high-voltage filter capacitors.
- Microcontroller & Logic Circuits: Programmed microcontrollers (MCU), EEPROM memories, and crystal oscillator timing circuits.
- Communication & Interface Blocks: Optocoupler isolation ICs (PC817, TLP281), RS-485 serial communication chips, and TVS surge protection diodes.
- Auxiliary Power Supplies: SMPS switching controllers (VIPer, TNY, TopSwitch series), high-frequency pulse transformers, and voltage regulator ICs (7805, 7812).
3. Rigorous Multi-Point Bench Rig Testing
Unlike standard repair shops that only check multimeter continuity, every board serviced under our Warranty Policy undergoes extensive testing on specialized inverter test benches:
- Dynamic Compressor Load Run: 45-minute continuous run connected to a live BLDC rotary compressor to verify IPM thermal dissipation and frequency modulation.
- Thermal Imaging Analysis: FLIR infrared thermal camera scanning to verify zero overheating spots across all SMD power resistors and driver transistors.
- Voltage Surge & Low-Voltage Simulation: Testing operation between 160V AC to 285V AC to ensure reliable performance on unstable Indian power grids.
4. Exclusions from Warranty Coverage
The warranty does not cover damages arising from external installation or environmental causes beyond the circuit board itself:
- Direct lightning strikes or catastrophic utility high-voltage surges exceeding 440V.
- Direct liquid ingress, rain water splashing into outdoor electrical boxes, or corrosive lizard/gecko urine short circuits.
- Incorrect technician wiring (e.g., connecting mains 230V directly to low-voltage serial communication terminals).
- Tampering, physical board cracking, or removal of the InverterACPCB holographic QC pass security seal.
5. How to File a Fast Warranty Claim

- Courier the board to our diagnostic lab. We provide priority 24-hour turnaround for warranty units with zero labor charges.
- Track live claim progress on our Track PCB Repair Status portal.
6. Frequently Asked Questions (FAQ)
Is courier shipping covered during warranty repairs?
If a fault occurs within the initial 14 days of delivery, InverterACPCB covers reverse courier charges. For claims after 14 days, the customer bears inward shipping while we cover outward express return shipping.
Can the 90-day warranty be extended?
Yes. Commercial customers and AMC contractors can purchase extended 6-month or 1-year lab warranty coverage. Inquire via our Contact Diagnostic Lab page.
