when was the last time u call in the service man? Looks like some internal choking building up so u'll need to call for servicing.

2 months ago and they did a chemical wash. It is only happen 2 days ago. The strange thing is the unit that never turn on get the ice build up once I turn on the other one for less than 10 min. Both units shared the same compressor.

thanks
