AC not cooling

[bazdad]

Does anyone remember summer in Florida before everyone had AC? Pensacola in the summer is hot, My 15k low profile dometic quit cooling. To replace do we go with a heat pump unit and where is the right place to buy? Thanks for your reply.

Be sure you t-stat is getting 12VDC from you battery system. That would be an easy fix for you...

The outside of the cond. coil rarely looks dirty. Did you take the cover off the AC and check to see if the cond. coil is clean on the inside? Craig

My Coleman A/C unit (2007) quit cooling recently. The blower works OK but the compressor isn't coming on and I've already eliminated the thermostat as being the problem. I suspect the start capacitor. It tested OK for shorts but may be open. I got the part no. from the manufacturer and now have to find an RV parts dealer that carries it. In the meantime I'm doing OK with fans.

In your case, make sure the thermostat on the wall isn't the problem.

Thanks every one. I will post next week when the fix is known.

If they will check it for you, they may be willing to do so at a reduced fee if you can take to them vs them going to you. We offer that to our customers. We have 30 amp hookup at our office that allows us to check RVs onsite. We discount the labor by 1/2 if they bring to us. You never know, having someone check it out could possibly save you some expense if it's fixable.

Way better than getting it fixed -or diagnosed- on an internet forum..:S

ddschuman is correct. Any tech can put service taps on, but like he said, MOST of the time the problem is something else mainly electrical (not much else it can be). I would suggest that you have an A/C tech check the system and you may find all you need is a new t'stat or relay or something simple. I used to have my own HVAC business also.

We just added a second A/C in our bedroom. I bought it from Makario's RV as they seemed to have the best prices. This was a 15k Atwood heat pump for just under $700 delivered. Make sure you have help getting the unit on top of the RV as it is bulky. Once I was able to get mine up on top, with the help of the DW and DS, I was able to maneuver it by myself while DW guided me.

two things come to mind when you tell me this. one is the unit is frozen up, happened to me once, I just turned off the unit and let it defrost and started back up and it worked again. if you lost Freon most RV dealers will tell you that you can't add Freon, they want to sell you a new unit. there are no openings to add Creon to these A/c's. I have heard of some guys on here that have gone to furnace and A/C places and they have soldered in ports and serviced but I think they are far and in between.

The unit is about 4 to 5 years old. We were out 3 weeks ago and it did not seem to be very cool but kept it liveable in 80 degree weather. I started to cool the unit yesterday and put out no cooling. It is a 15k unit with clean coils and clean ducting. I think the unit is sealed without any place to charge the unit. I do not know where the cheep place is to purchase. I will install myself.

I would still get it checked. From your original post it wasn't stated what it was or wasn't doing other than not cooling. There are many things that could be bad other than losing the freon. I would take it to a place that does repairs as well as sales as most tyimes they will eat the diagnostics if you purchase a unit.

Assume by this comment your compressor is working but it's just not cooling. If so - then chances are you lost freon and that usually requires paying someone to find leak/attach recharge valves/recharge or replace the unit (only need upper portion of AC).

Before buying new unit I would clean both compressor and evaporator coils along with filters -- doesn't cost anything and if nothing else will eliminate the obvious.

I would get it checked out. A 2005 isn't very old. It could be a capacitor which is quick and easy fix.
