Toget proper heat, keep your temp setting at 30+ degree and also mode in "heat"position. If still no heat, check your heating sensor for closed circuit by anOHMs metre.It it's with RV, check power to RV.If it's with heatingelement check power to element. If power is there but still no heat meanselement defective. Replace new heating element. Thanks.

What does a flashing light mean?

a flashing light could mean any number of things. normal operation, number of communicating components, a minor alert such as a filter change or major alarm like pressure error or control board problems. first we would need the number of flashes and /or sequence of multiple flashes AND the model number of your "split heat pump!"

Light 2 and 3 flash in the condenser outside in my mini split system dual zone AC/Heat Pump. My second floor AC unit does not work. Green light comes on, vent opens, green light flashes.

Flashing lights normally are an error code.. this could be anything really. You have to find out what that code is telling you (manufacturer specific). You most likely won't be able to fix this yourself if you can even find what that code means.. your best bet. Get the installer back. Unless you did it yourself. Then your gonna pay a lot for service unless you find someone willing to look at it (not many people will look at systems they didn't put in.)
Otherwise you have a ugly box on your wall that wi?l only flash some lights at you..

I have a red and green light flashing, fan work on inside but unit will not come on outside

There should be a diagram on cover that also show you what codes the flashing lights mean. I will need the model number of your outdoor unit to tell you what the lights mean.

Fujitsu asta18lcc has a constantly fast flashing green light and the red light flashes slower 5 times with a small gap between each 5 flashes. Unit wont work at all apart from lights.

The red light (operation) flashing 5 times can be one of four things depending on the green light (timer) but the green light should flash at the same rate as the red light, not faster - either 2,3,5 or 6 times. Anything other than these is abnormal and you will need a tech to diagnose.
Could be a faulty controller board or compressor.

Lamp never fires Unit goes right to cool/shutdown.

The ballast might have gone bad, you'll need to check the output voltage of it. In some projectors, the power supply/ballast are combined as one PCB instead of 2 separate boards.

Clean light flashing

this is a safety failure of the unit not heating the water properly. if you push the " water heat, air dry, water heat, air dry" in that order, then it will go into the program mode and clear out that failure code.
then try the unit again, if you open the door during the heat cycle or it doesnt heat properly it will happen again. make sure you have hot enough water, 120 degrees, going to the unit and dont open the door after you start the cycle. if it continues call sears for service as it has a 1 year warranty.
