    The right light will stay on for about 3 seconds, then goes off for about 3 seconds. Off and on, off and on...

That is an error code.

count how many blinks after a pause and that would be the error code.

could be 4 , 5, 7, or 9.

you could reset it by un plugging or removing power for ten minutes and try it again.

if the problem would re-occur, then there is something wrong with the unit.

as it runs, observe everything and keep me posted. see if the fn outside is running, if the filter is clean, or if the compressor is running, etc.

tnx 4 using fixya,

Alpha Romeo 156 My Left hand indicator light stays on continually, does not flash. and when I turn the hazard light switch on both indicators continually glow.

Generally speaking, symptoms of a bad or failing turn signal bulb are usually the your case, either it's the front left or rear bulb. Varies for different vehicle makes...common signs include:
  1. turn signal light staying on solid
  2. or blinking very fast
  3. or either sides of the bulbs stop blinking altogether.
To test this, make sure you reconnect everything you disconnected.
Turn the left signal light on; go to the front of the vehicle, is the turn signal bulb illuminated? If it lights up, even though it is not blinking obviously the bulb is okay. If it doesn't, replace it- problem solved. You'll do the same procedure for the rear turn signal Is that lit up? If not replace the bulb and the problem is solved.
Another common failure is when the turn signal blinks really fast, same procedure as mentioned above.
If both bulbs for the left side and right side illuminate but don't blink, the problem is in the steering column turn signal switch.
If the left or right side blinkers don't work properly at all...then check the integrated hazard warning/turn signal flasher relay- that may be defective; again, that's usually the case if both sides of the signal light don't work.
If you are blowing any fuses related to the flasher system, you have an electrical overload in the turn signal circuitry.

I had the same problem on a 92 & 95 Dakota years ago, replaced the turn signal switch in the column & found a loose ground wire in the harness back by the tail lights. Never had a problem again. If you're gonna try to replace the switch you will need tamper proof torques bits just FYI. Good luck. Let us know how it turns out.

Operating indicator light is flashing on Mr.Slim A/C

I had the same problem and I found it was that another unit had the heat running while I was trying to run AC on another (they're both attached to the same condenser) so it could only run heat or AC not both. Turn off the heat!

When I turn on my HL-T5687S, the screen remains black and there are 3 dots on the lower right hand side of the panel?

My TV is (same model is doing the same thing). The manual shows that the 3 blinking lights indicate "LED may be defective. Please contact a certified technician."

Note: When I power my TV off (unplug) and back on, the TV's left indicator light is solid for less than a second ("Stadby state") then the right light blinks ("The picture will automatically appear in about 15 seconds") for about 15 seconds. This pattern is repeated numerous times (I think it was 5 times). I believe the TV must be failing some power-on test. Aftere failing 5 times it gives LED may be defective indication.

The left indicator light is blinking and I have no heat. I have tried turning the breaker off and on and I have tried emergency heat setup and I still end up with the same problem

Turn the whole unit off at the circuit breakers. Let it completely defrost. I left mine off for two days until the outside weather improved. When I turned the circuit back on, it was fine.
