What it means
Friedrich lists code 22 as the compressor pre heating process and says it is normal mode in cold weather.
Urgency
Not an error
This is a status display, not an error code.
Likely causes
Homeowner fix
Wait for the compressor preheat process to finish in cold weather. Service is only needed if the display never clears or heating does not resume.
When to call a pro
Call for service only if code 22 never clears, heating does not resume, or another fault code appears.
Repair vs replace
This is a normal cold-weather status display, not a repair-or-replace decision.
