How to Fix / Troubleshooting
Safety: Use caution when working around electrical panels. Turn off main power if needed.
- Step 1 – Check breaker: Locate the breaker labeled for the Senville air conditioner and reset it if tripped. If it trips again immediately, stop and call a technician.
- Step 2 – Verify outlet or disconnect: If the indoor unit is powered via a dedicated disconnect, ensure it is ON.
- Step 3 – Inspect indoor wiring: With power OFF, remove the indoor unit cover and check that line and neutral wires are securely attached to the terminal block.
- Step 4 – Test remote: Replace remote batteries and ensure nothing is blocking the IR receiver.
- Step 5 – Board replacement: If power is present at the indoor unit but there is no display, the indoor PCB or power supply module may be faulty and require replacement.
