Amana mini split question

[davidlee]

Last night I got a notification on my phone of a communitation error and to call my dealer(which I found out they went out of business).
I tried turning off both breakers and turning them back on but everything was still completely dead. I then called another Amana dealer and scheduled a tech to come out.
Several hours later the unit came on by itself and is working properly now.
Has anyone else had this happen?

Is it a communications problem that prevents the call for cooling via your wifi thermostat or wifi mini-split system?
Short of a HVAC tech coming out, and if you have the capability to electrically troubleshoot the problem,
I think it is the control side (low voltage side) rather than the system side (high voltage) from the description of the problem.

I never had a system that would fix itself. I guess I will have to wait and see if it continues to work properly.

Think the unit had a glitch and when into the weeds. Reset the unit by turning off the breakers.

Update. The unit has done the same thing four nights in a row. I checked the drain line and it is clear.
sometime when I reset the breakers it will come to life sometimes not. Every time it shows a communication error. I threw in the towel and a service tech is coming out this evening. I did call Amana and they did say the unit has a memory which will tell the tech what the fault was.
