Put a new compressor in 2011under warranty. Unit was installed in Oct 06. When it gets going, cools fine. Unit inside will not stay on. I was playing with it yesterday trying to get it to turn on. I repeatedly hit on/off button. The indicator light would blink and unit would beep. Then the vane that positions the airflow would pulsate. The unit would then stop. Eventually, it would turn on. After a while of this, I would try to get it going again, now nothing happens. The light does not blink, there is no beep, nothing as if there is no power. I thought maybe there was an internal circuit breaker. I left the unit alone all night. There is still nothing this morning. In the unit, by the circuit boards, it feels warm, even though it was not on all night. Someone told me the board (s) might be bad. I don't have a meter.
the unit will not do anything anymore. The fuse (glass fuse) on the board appears to be ok. I have not seen anything on the board that would leave me to believe that it is burned or anything. I will look again. This unit is not under warranty. I haven't taken the cover off of the outside part, but I will check it out too. The thing is, the unit will not even turn on inside anymore. When I had the bad compressor before, the unit turned on fine but just wouldn't cool. This unit (when it did turn on) cools just fine. How expensive are these boards in the inside unit? They look like they are just unplug remove and plug in a new board. There are two of them. Which one would be most likely to go bad? Where would I be able to buy them?
You say they are not worth replacing. Are you saying I need a whole new unit???? Also, how much do they cost so I'll be able to decide course of action.
