What to do if Daikin FTXS30HVJU operates but does not cool or heat?
- RRoger WilliamsonAug 1, 2025
If your Daikin Air Conditioner operates but doesn't cool or heat as expected, several factors could be at play. Begin by conducting the wiring/piping error check as described on the product diagnosis nameplate. Also, ensure that the main unit’s thermistor hasn't dismounted from the pipe holder. Furthermore, set the units to cooling operation and compare the temperatures of the liquid side connection pipes of the connection section among rooms to check the opening and closing operation of the electronic expansion valves of the individual units. Finally, check for insufficient gas.
