daikin no heat
i have a sky air one to one what happens in the heat mode, eveything come on, and for about 2 min i will get the ssupply air up to 94degf and the discharge line will also. and then that temp drops back down as if a valve closes the outdoor unit still runs and then cycles off with no fault.

Re: daikin no heat
Hi
So are you saying the unit thinks it's achieved it's set temp and therefore shuts down as it should? If so maybe you have a faulty TH air on thermistor?
Doe's it work ok on cooling, switch off on on with temp?

Re: daikin no heat
Check the outdoor airflow also. Is the coil frozen?... dirty?... fan running properly?

Possibly a blocked filter in the outdoor unit.
