If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.

The installation manual linked by Luxaire distinguishes stored faults from current system status.

Luxaire maps the AL19 product to a shared model manual
Luxaire’s own AL19 page links installation manual 5512532-UIM-D-0320. That publication explicitly includes AL19 alongside the other listed model series. This page uses the AL19 scope in that shared publication; it does not substitute a different brand’s unspecified AC instructions.
According to AL19 19 SEER Two Stage Air Conditioner | Luxaire®:

According to Luxaire-linked AL19 two-stage AC installation manual, 5512532-UIM-D-0320:
YFK, CC17, TC17, YXT, AC19, AL19 SERIES
AL19 separates the fault memory from the status display
The control retains recent faults, while the status display reports the system state. Record the visible indication and whether the complaint is happening now. Leave button operation, control-box access and energized electrical checks to the contractor so the original fault record remains available.
The Luxaire-linked AL19 two-stage AC installation manual, 5512532-UIM-D-0320 also explains:
The control stores the ten most recent fault codes in memory, for review by the service technician.
The control has a status LED and two 7-segment displays.
A red LED indicates that a system fault is present.
The installation guide identifies the contactor power connection
The electrical-connection section names the contactor separately from the display. Tell the contractor whether the indoor blower or outdoor unit responds to cooling. An absent response or a red light should be preserved as an observation rather than treated as a conclusive contactor-replacement decision.
The Luxaire-linked AL19 two-stage AC installation manual, 5512532-UIM-D-0320 gives this further guidance (excerpt 3):
Make the power supply connections to the contactor.
