F 22 alarm

Compressor coils vacuumed and flushed with compressed air. Unit standby indicator stops flashing after 10 minutes, and circulation fan shuts off after about 20 minutes but compressor continues to run. Any request for cooling turns circulation fan back on. Unit seems to operate fine, but after circulation fan turns back off, unit generates F22 alarm in 45 minutes.

Defective temp sensor? Should circulation fan run the entire time this unit is on? Filter on rear of unit is clear and offers plenty of air flow.

Your unit is over pressure. This can occur if the room is too hot where the unit is operating, especially if the unit is being used for long periods of time.

Hope this helps.

 

Thank you,
