Thanks so much Denny, much appreciated!

I have no issue with the the mini splits, they work great and are a very straight forward installation. However heat Pumps also work great in my application and the condenser is hidden. I would need to mount a platform somewhere for a mini splits condenser and find wall space for the interior unit ( I have none). It is a great option for a lot of folks.

Denny,

I am sure I could install it. If I did I would rent a material lift for $75. The unit would cost me about $1,500. A few years ago I would not hesitate, but now I am 67 years old. I would also need to pick up the rental lift, get it in and out of my truck and return it. The unit weighs a little over 100 lbs. That's my top end of lifting at this point. The best bid I have so far (I always get three bids) is about $2,000 turn key. I could save about $400 if I do it myself but if I screw up and drop it or something it's on me. I am on the fence. I would love another win but I am not sure on this one. So simple yet it has its has some challenges. 

I am thinking it over,

Mike

Hey Glenn,

I am on the move all the time and I am in a 5th wheel. I have installed several mini split's on telephony buildings for Centurylink and am a fan, but I can't see one on my 5th wheel unless I was stationary for long periods of time. 

Thanks,

Mike

Denny,

You are correct on both accounts.  It is locked up. I did a couple of other tests. I unhooked the compressor and set the stat to call for both heat and cool. The breaker did not trip. I also found I had 120 volts on the start relay so I think the control board is good. You are also correct it is a reversing valve.

I really do appreciate all your responses. I wish I could have fixed it but not this time. Time to blow some cash, but you got to admit I did not just lay down and give up easily.

Some of you folks thankfully have been trying to help me troubleshoot why my 2015 rooftop Dometic Heat Pump (#651816). The units fan will start but shortly after trips the breaker. I have gone through several things to try and diagnose what is causing it. As they say a picture is worth a thousand words words so a video showing testing the compressor for short to ground, replacing the breaker and testing and replacing the start and run capacitors may give you a better understanding of what I have tried. The fan and compressor relays are mounted on the control board so I can't just pull them off and just replace. I appreciate any help I can get. I am not an HVAC tech, just a home owner with enough skills to be very, very dangerous that likes to fix his own stuff and doesn't give up easily. Thanks again for any help you can provide, Mike

Update. I still need help. 

Thanks again Denny,

I did check for ground on each terminal and found no short to ground so I am thinking the problem is not the compressor.  I think that the starter relay is located on the control board. If the control board is bad I think I will have to replace the entire board. I could not see where I could remove any of the relays. Per your response I will also order a start cap. I have already ordered the run cap and a hard start cap. If it turns out to be the control board I might be able to use new capacitors down the road. I have two heat pumps on our rig. Again Thanks so much for all your help. Merry Christmas!

Hey Denny,

A video is worth a thousand words so let me know what you think.

Thanks all. I appreciate all the advice. I will report back as soon as I get the new capacitors installed. Got my fingers crossed.

Merry Christmas to you,'

Mike

Yes this is my video. 

I have ordered the hard start and the original start cap and will hope it fires up.

Thanks Denny, I will do that. 

I do have a multimeter but not an amp clamp. I will check everything I can and report back to you all. Thanks so much for taking the time to offer tips. Mike

My four year old Dometic Rooftop Heat pump is tripping the AC breaker. I can re-set the breaker and it will stay set until the thermostat calls for either cooling or heat. Up on the roof I can see the fan does not attempt to start nor does the compressor. I hear a very faint click and then the breaker trips. The fan spins freely and I can set the thermostat to just "Fan" and that does work. I cannot smell any kind of burning nor do I see and damage to any wires. I am thinking start capacitor either fan or compressor.
