Homeowner? What Goodman code Comfort Alert last alert recall means for you

Usually minor Your air conditioner is reporting: Last alert code replayed after power-up. This code is usually informational or minor. The safe checks below often clear it; call us if it keeps showing up.

Safe things you can check yourself

Check the thermostat: right mode (Heat or Cool), set a few degrees past room temperature, and fresh batteries if it uses them.
Check both breakers and the outdoor disconnect box beside the outdoor unit; all should be ON.
Look at the air filter. If it is grey and clogged, replace it; a blocked filter causes many shutdowns.
Keep about 2 feet around the outdoor unit clear of leaves, grass and debris.
If you see ice on the pipes or the indoor coil, turn the system off and run only the fan for a few hours, then call a technician.
Try one reset: turn the power off for 30 seconds, then back on. If the code comes back, stop resetting and call a technician.
