How to fix no cooling - r-32 glxs/alxs condenser: step by step
- Check 230 V at the unit and at the transformer; check 24 V from the transformer.
- Check 24 V on Y from the thermostat; then 24 V at the contactor coil - none means check the pressure switches and wiring.
- Contactor energized but not closing: replace it.
- Compressor not running with the contactor closed: check wiring, run capacitor, overload and windings. A hot compressor should be allowed to cool and retried.
- Windings open or compressor locked: replace the compressor.
- Compressor runs but does not pump: check for a clogged piston or faulty TXV, then confirm charge with subcooling/superheat.
- Indoor blower not running: check 24 V on G from the thermostat and voltage to the indoor motor; replace the board or motor as found.
