AC still getting HPF

georgec14

there is a solenoid in the unit that lets the water from the pump thru. if this is stuck no water will pass though. mine has stuck before because of ice. take the top off the ac  and /remove supply hose / turn on ac see if water is getting there/ if no water passes though  then solenoid is stuck.  it can be replaced. good luck captain.

Glad to hear enjoy

Keep in mind the faria gauges that you likely have are junk and in general unreliable if they are old.  I don't trust mine at all.  Smartcraft gauges are on my short list.

@craigswardmtb I do have faria. How old is old?.  When replacing, do they go right into slots of old gauges?

There are plenty of threads on this guys.

Lots of threads but in general you can send them back to faria to be fixed for an exorbitant expense and expect them to go haywire again in a few more years. Or replace them with something more reliable.

appreciate it @craigswardmtb.  So to make Handyman happy Ill get back on topic...joking.  A/C works great(except I forgot to close seacock before I left for the weekend) but I can not get it to kick back on when it reaches the set temp.  I set the ambient temp and it shuts off just fine when it reaches the set temperature.  But it wont kick back on when that set temperature is reached or passed, in this case a higher temp.  The fan kicks on sometimes but no A/C.  Another programing issue?

It won't kick back on right away. It'll go passed the desired temp by a degree or more, to avoid the compressor from clicking on and off to frequently.

Interesting and makes sense.  I let it go pass by about 3 degree and did not click on.  This is normal?  Why would fan kick on without compressor?

There are different settings as far as the fan kicking on with or without the compressor.  I have mine set that the fan just goes to a lower speed when the compressor is off, but it still blows.  & Mark is correct, it will go maybe 2 degrees past and then kick on.  3 degrees and not kicking does not seem right.  You may just want to go thru all of your programmable settings to see what they are all set at.

That is the short cycle delay, you can adjust it.  It prevents the compressor from cycling on&off.  I believe the factory reset setting is 2 degrees.

Thank you everyone, I will play with the programming next time I am down.  Being that the fan kicked on I have to believe its working just needs to be adjusted.  

A second question I have is cleaning the AC.  I bought this A/C coil foaming cleaner for my previous boat and was curious if this will do the trick.  

MarkB

Fan will not overheat, it just spins, so you can blow air all day long without a problem. Compressor on the other hand can over heat, over pressurize, especially if it goes on/off frequently. So fan keeps running, blowing past the compressor, and if it's on the air will be heated or cooled. If it's off the air just blows past and returns at the same temperature. 

Check if there is a setting you can change to get it to kick back in sooner. Not sure, but I seem to remember something. Now are you talking 3 degree F or C? 3F is probably okay, 3C is not. 

06Rinker270

Yea it sounds like a programming issue, or me being impatient and not knowing it will come back on.  I am talking Fahrenheit.  

MarkB

3F is probably okay. When mine goes off it drops around 1.5C before it kicks back on, which is about 3F.

Very good Ill give it more time this weekend and see if it comes back on.  Appreciate the help everyone.

That's a good coil cleaner
