I have a Comfort Star ductless ac/heat combination. The fan

Customer Question

I have a Comfort Star ductless ac/heat combination. The fan will blow when the remote is pushed from the mode position to "fan" and "dry". When I change the mode to "automatic" or "heat" the fan shuts off and the # ***** indicator stays on. It did not kick on after 4 hours yesterday. Any suggestions?

This is a mini split heat pump. Outdoor Model CHP018CD (0).

this sounds like a sensor went bad which controls defrost cycle. It thinks your coil is iced over...does the outdoor unit when this happens?

I understand the sensor possibility. I didn't understand your comment about the outdoor unit - "does the outdoor unit when this happens?" When what happens?

When the indoor is supposed to be running...but is the outdoor section running or is dormant also?

No, the outside fan isn't running.

Sounds like nothing simple so I probably need to call a local HVAC tech. Is that what you think?
