What it means

L6 means the outdoor unit is detecting a compressor motor ground/short condition. This is an electrical safety and compressor-drive diagnosis.

Urgency

advisory

This is not usually an immediate safety hazard, but do not keep resetting it. Try the safe homeowner check below; if the code comes back, schedule service.

Likely causes

Brief power event, brownout, or unstable supply voltage
Loose power connection, reactor, or outdoor electrical component problem
Inverter/IPM protection or current-detection fault
Compressor winding, drive, or outdoor board fault after power checks pass

Homeowner fix

Leave the system off after one failed reset. Do not open the outdoor cabinet or keep trying to start the compressor.

When to call a pro

Call a licensed HVAC technician if L6 appears. Tell them the MXM table lists compressor motor ground/short circuit.

This code points to compressor and electrical or inverter work - get repair quotes from contractors in your area.

Repair vs replace
