I cleaned out the water tube and ran water through it, which

Hi! I cleaned out the water tube and ran water through it, which went fine (though there was a fair amount of gunk...) but the system went to "waiting," and then "alert 31, communication with compressor). It's been at least 20 minutes. I remember that the other time this happened, there was something about the position of the washer thing attached to the upper cap. Is there a way to reboot the system? i.e., flip the circuit breaker? and if so, what voltage would that be? The one I think reads "air handler" seem to be 60, would that be it?

I have a Rheem RBHP17J06H1 Air handler that the blower does

I have a Rheem RBHP17J06H1 Air handler that the blower does not start up. If I spin the blower by hand as I turn on the breaker it starts and seems to work normally until the room reaches desired temperature then will not restart again. I am no expert, but it sounds like a start capacitor issue. Problem is I do not see one in the wiring diagram or on the unit but an online parts locator lists one part # ***** My question- Is this built into the motor and if not how do I access it

Trying to troubleshoot why my central air is not getting

Trying to troubleshoot why my central air is not getting cold enough anymore. First off let me say that this is an older model from mid 1990s. I want to see if I can get one more year (this year) out of it. So using Google and advice form Just Answers I thoroughly cleaned out the outdoor condensor fins (removed fan and used the foaming fin spray on both sides of the fins. Straightened the really bad bent fins, and gave it a good hosing down inside and out). For the air handler in the attic, I did an in place evaporator "A" coil cleaning. I used a 2 1/2 gallon weed sprayer filled with Nucalgon Power'C Evap cleaner and did this twice. I straightened the coils that were really bad and I vacuumed and brushed the coils . I did an LED light test and everything looked good (I could see the light going through both coils.. I also did notice that there was a lot of leaking in the cold air returns where the flexible ducts connected so I started sealing all of that with foil tape and I just bought mastic glue for the rest. Now my house has started to cool but I still can't get it down to 75 only to about 79. So now for my questions.1. After doing all this work I saw this outside today on the condensor (see pic) the connector is covered with ice. What does this mean and is there a way to resolve this on my own? When it ices like that should I shut off my system until it goes away in other words am I just wasting electricity at this point?2. If I need more R22 is it true that it is cheaper to replace the whole system because R22 is no longer made?3. If I need a new system does that usually mean new air handler and new condensor unit? Thanks
