The outside unit of my Trane 9,000 btu 18 SEER Mini-Split

Customer Question

The outside unit of my Trane 9,000 btu 18 SEER Mini-Split system is covered with ice and has shut down. I do not know what to do.
Model - 4MXW8509
Is it possible this system has a safety shut off in case of a problem of this or other kind?

Unit should have a self thawing defrost timer. Sounds like it is not going into defrost. Best thing to do until you can get a technician out is to locate disconnect by unit or breaker in power panel and kill power to the unit.
