Hello Experts,

My Comfortmaker Attic unit (Model R410A) shuts off by itself. We are at below freezing temp in MD. When I go up and open the front panel it starts by itself and sometimes it stays on until thermostat cut-off setting, but sometimes turns off again after couple of minutes.

The unit is two years old, not sure whats wrong. Is there anything I can do to diagnose or fix the problem? I was going to call a tech, but thought it might be something simple that I may be able to fix. Any advice would be appreciated.

Thanks
