My Daikin air con won't heat
I have just switched it on and off a few times.
Do you have it set on the correct mode (Heat), not remnant from summer setting ?Try Auto mode.Outdoor fan running ??Try a Hard reset by turning off power supply....leave 30 secs then retry...it may take 10mins for the compressor to come back on.If these things fail it is time to call the cavalry I am afraid as there is likely to be an internal fault.
