Panasonic aircon inverter module repair in Singapore
An IPM or inverter-board fault on a Panasonic system can be the power stage itself, or the supply, cooling or load it drives. We test the power stage, supply, cooling, wiring and connected load, explain what failed and quote after diagnosis.

Signs your Panasonic aircon needs an inverter-module check
These symptoms can involve the inverter power stage, but they can also come from its supply, cooling, connectors, feedback, main board or connected compressor or fan.
An IPM, power-module or inverter-board code appears
A Panasonic inverter-related code identifies the power stage or protection path. It does not prove which replaceable assembly has failed.The outdoor unit starts, trips or stops under load
A weak power stage may fail as demand rises, but the supply, cooling path and connected load can create the same protection.Cooling stops across several connected rooms
A shared outdoor inverter or driver fault can stop the connected system even when indoor units still respond.
Examples of Panasonic systems we check
CS-PU and CS-MPU standard inverter systems
CS-XU X-Premium residential systems
CS-MU slim ducted or PACi systems, with scope confirmed from the exact model
Model not listed
Send photos of the indoor and outdoor model labels, plus the error code or a short video of the symptom.
It may not be the inverter module
Before ordering a model-specific module or driver board, we check three problems that can create the same code, trip or no-start behaviour.
Supply, connector or communication fault
Voltage imbalance, loose terminals, damaged harnesses or a failed main-to-inverter link can stop a healthy power stage.Cooling or feedback fault
A blocked heat sink, failed fan, temperature-sensor circuit or current-feedback problem can trigger module protection.Compressor or fan load fault
A locked or electrically damaged load can create real overcurrent while the inverter module is protecting correctly.
We match the code to the exact IPM, IGBT, inverter-board, fan-driver or compressor-driver stage, then test supply, connectors, cooling, feedback and the connected load. How a job runs, from first message to booking.
What is different on Panasonic systems
Panasonic manufacturer fault tables list one code for inverter module faults: F96.

Is Panasonic inverter module repair worth it?
Parts and timing
The correct Panasonic inverter power stage may be a separate IPM/IGBT, a driver board or a complete outdoor-PCB assembly. We confirm the exact outdoor model, board revision, supported repair, part number and distributor lead time before you approve work.Our recommendation
Inverter-module repair is usually sensible when the exact power stage is confirmed, the supported module or board assembly is available, and the compressor, fan, supply and cooling path remain healthy; an older system with a damaged compressor or several board faults needs a closer repair-versus-replacement comparison. Panasonic systems commonly have a service life of 8–12 years. For a system over 10 years, major component failures usually favour replacement. Efficiency has dropped, parts for older CS series may need longer sourcing, and a new unit pays for itself in energy savings.
If replacement makes more sense, we compare the repair quote with a suitable new system. See our aircon system replacement process.
Other Panasonic repair checks
If testing rules out this part, these are the next checks on the same system.
Workmanship warranty
We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.
Labour
30-day workmanship warranty. If the same fault returns from our repair, we come back and the labour is on us, with no second diagnostic visit fee.
Parts
Parts carry the distributor's warranty for that component, so the term varies by part. We tell you both terms before you approve the work.
