What you have is two fans, one for the outdoors and one for the indoors.You indoor fan is not running and it is not a good idea to run your unit. There are several reasons for this fan not to be running, but the most common is that it is bad. AC mechanic or good electrician can check this out.

I have the 5 day. 2 day programmable thermostat. Installed in the winter but now that it is summer air conditioner won't come on. Can you please advise?

You should always include model number in requests. More info is better. In general, there is a setting for Heat and cold on cheaper thermostats. Mine is like that. It works for heating in winter and you must switch it to "cool" for summer. I assume you do have an AC unit for summer. Who wired it up? was it ever working? Did it get installed during winter? The wiring may be wrong, there are a lot of possible ways to wire. If you are not good at that (and why would you be here if you were?) better get a tech to check it out. In the old days, Edison might send out a tech for free to advise (not fix) if there is a possibility of short (dangerous).

Our AC has had a lot of trouble over this summer and we recently had an issue just like yours. We ended up calling an air conditioning repair technician and had it resolved. It was the best thing that we did this summer because it is really hot right now but inside it is great! Ontario CA Air Conditioning repair Penny Plumbing

No heat but fan keeps running

If the air conditioner compressor runs all the time the main control board might be defective. The main control board provides the voltage to the fan motor and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.

Compressor ?

Sounds like you are over heating the compressor, try cleaning the out door unit coil. Take a hose and blow water through it, be carefull not to bend the fins.

My LS-H186 VML 1Metal Art Cool 12000 BTU Air Con does not heat up

You should also check the outside unit to make sure the coil is not clogged with dirt or grass clippings and the fan is working. The reversing valve that switches it from cool to heat could also be a problem. If it isn't shifting it will not switch between heat and cool.

Heating does not start appears a light circle with am asterisk and small drop inside the circle ()art cool lg

possibly a freon charge issur, or thermistor problem, in the heat mode the indoor coil has to be a certain temp. for the fan to run, if it does not reach the temp because of a low charge or a sensor that is defective, could be more complicated but usally not. Note: if it is low on charge you have a freon leak that needs to be repaired.
