Our inverter is Heart-Freedom which is a invertor/converter/charger combined.

Thanks for that info. So the air conditioner doesn't run from either shore or genset power. Do the coach interior lights still work? I'm trying to ascertain whether you have any 12vdc power, which is distinct from 120v shore & genset power. The lighting is 12v and thus runs from battery or the converter portion of the Heart Freedom inverter.

So far I'm not seeing how they arrived at the inverter diagnosis...

yes we have 12volt lights.The invertor will run everything it is supposed to.

So, why then do they think the inverter is at fault?  If it inverts, and converts (provides 12v from shore power), and charges batteries, what else do they expect it to do?

The more info we hear, the more the issue points to the Auto Transfer Switch, which changes the power source from shore cord to genset, or the wiring between the ATS and the load center (where the 120v breakers are located).  That's the critical path for 120v power from shore or genset.

We only get 12v from the invertor not from shore power or generator. WE run the motor to charge the batterys.

That's perfectly logical if the generator/shore power Automatic Transfer Switch has a problem.  If it's not sending power to the inverter/charger, it won't be able to charge the batteries.

Like Gary said, everything you're saying points to a problem with the generator/shore power ATS.  Not with the inverter the repairman wants to replace.

I'd take the motorhome to another repair place and get a second opinion.

Sorry to be direct.

What kind of an answer are you looking for.  Several people have told you they think the problem is your transfer switch (ATS). 

All your one line, vague replies, get confusing. 

It would really help if you took the time and effort like others have provided, and respond with a 150-300 word review, in detail, just what you have done, what you have measured, etc.  Start with copying all your one line replies and then expand with detail.  I think if you copied all your replies and looked at them in sequence you will find them confusing as well. 

For example in your latest reply you state:

Well your inverter is directly connected to your house batteries (note: I did not say your engine battery).  If you are getting 12V from the charger side of the inverter then that 12V is going to the house batteries.  So what voltage do you measure, and where did you measure it to say your batteries are not charging from the inverter, but yet you have 12V coming from your inverter.
