daikin no heat

[k1shifflet]

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.

Maybe you need to clean filters!

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?

Check the outdoor airflow also. Is the coil frozen?... dirty?... fan running properly?

Best to do a proper system check,mate.Thats electrically and mechanically as well...

Possibly a blocked filter in the outdoor unit.

i found that the reversing valve is sticking. took temp across to verify this. ordered new valve and going to replace
