Discharge the inverter capacitors before service
Carrier · DLCM(R/H)B multi-zone outdoor units with DLFSHBH high wall indoor units (Midea, Carrier, Viessmann)
The big electrolytic capacitors on the outdoor board stay charged after power-off.
- Turn power off and lock out.
- Put a resistor of about 100 ohm 40 W (or a soldering iron plug) across the + and - capacitor terminals before touching the board.
