Not many flowers, just a few here |
It has continued cold and windy, I don't think the high got much above 50 today. I never remembered Florida being this cold. I'm sure a lot of people are complaining about the weather and I'll add my voice too. I got up in good cheer and started working on getting the A/C to work in heat mode. It would cool air quite nicely but wouldn't switch over into heat mode. So I thought I would attack the problem by switching out components since I had two A/C units, one for the aft cabin and another one for the main cabin.
The key component is the solenoid that moves a metal slug in a tube that points the flow of refrigerant to either the cooling side or heating side. The slug is spring loaded to cool but the solenoid can be activated to push it magnetically to the heating side. So if the coil is defective, or the slug is stuck or the control board doesn't send the right electrical impulse, then the slug remains in the cooling position - which is has so far.
Well, I thought this was simple, I'll check to see if the solenoid was activated by sticking a metal screwdriver into the donut hole of the solenoid and found that it was not activated. That could be due to either a defective solenoid or no electrical current from the control board. So I switched the solenoid with the one from the aft cabin - no difference.Then I switched the control board with the same result. Then I measured continuity from the control board to the solenoid - an open circuit. So I thought I found the problem, an open somewhere between the solenoid and the control board, perhaps a bad connection.
But my problems were only beginning! I had been using the genset to power all the tests, turning it on and off and when I looked over at the display for the genset, I saw a blank LCD. The display was not powered. Well, that's not good I thought. With a blank control board, there's no starting the genset, there's no manual override, it's the push button control board or nothing - don't you love modern electronics...
Now everything came out of the aft locker where the genset was located and I started to look at that problem. Nothing made any sense. The 12v came in and nothing happened. Calls to the Kohler help desk was no help, they wanted you to contact a local dealer which I did and found out they had a three week waiting list! Likewise for marinas in Stuart, everybody is backed up with work. I'm now looking at Ft Lauderdale but I don't have high hopes for that either.
Now it's cold, under 50 and the wind is still howling, not a good cruise south this year! We're aiming for Hobe Sound Wednesday night and West Palm Beach after that. followed by Ft Lauderdale - got to get to warm weather!
