Having problems with your Air Conditioners ?

When I touch the aluminum heat transfer fins on my home A/C unit, they turn to power. I understand the different metal problems (copper/aluminum) with electrolysis, but what activates this problem. Are there ''sacrificial'' anodes to eliminate this. Can rain/water start this process. The unit works OK but I think it is loosing efficiency.

Answers :

Your right, it will lose efficiency. Acid rain causes this and with the right chemical fumes around your unit, it can cause it. There are no anodes that will help. Time to replace the coils or the whole system.

This is a Fujitsu floor mounted aircon unit. In either heating or cooling modes the 20amp circuit drops out almost immediately after the soft start switch activates. The on board 5 amp fuse is not blown. The fan inside this unit runs very briefly before the breaker lets go. The wall unit fan is unaffected if used by itself.

I have 2 dometic roof top units on a 2002 MH that I recently purchased. 1 of the units only runs on high speed, the stat has a high low switch, the unit cools fine. The second unit, the comp starts, but the fan only hums, the shaft turns fine. I switched the start relay from the other unit, same result. I suspect that the start winding is open, but haven't checked yet. I am not opposed to replacing the unit because of age, condition of roof cover,and suspected cost of parts. Would appreciate any

Hi, unit # 2 sounds as though the run capacitor may be open, shorted, ect.When you say you changed relay, I assume you were talking about the capacitor. If the motor didn't run when you changed it, you do have a bad winding, or open as it just hums. ... Dometic Air Conditioners
