onan repair bill question

I've been having trouble starting the Onan 2500 in my AF1150, and posted earlier. I finally gave up and took it to the nearest Onan shop. This is the actual Onan factory shop here in Houston. They're telling me it's going to cost 600 bucks JUST TO DIAGNOSE IT!! I'm blown away. I can buy a brand new Honda for a grand or less. Is this normal???

  • One more thought, take it to a RV repair place and have it serviced. Who knows, maybe the servicing will get it running and would probably be quite a lot less.
  • If it were me, I'd google the model number and description of the issue. You might find a simple fix you could do yourself. Tons of YouTube videos.

    As well as finding a good independent shop (as opposed to the dealer) try to find a good local repair guy. I'd even try to get ahold of a Mobil RV service guy and talk to him..

    Good luck to you.
  • Its a pretty basic unit, if it isn't starting you should be able to diagnose that without fully dropping the unit. You can lower it down on the front to get access to the plug and what not. Check all your basics, is it getting propane? Spark? Air? Low on oil?
  • Other than basic maintenance, I cannot see how you can work on a built in generator other than pulling it out of the enclosure. This will be expensive if you cannot at least do this yourself.

    I like the convenience of remote start, not having to carry another fuel source and not having any setup or security concerns of an external generator. This convenience knowingly comes at a cost, but you have to decide if this worthwhile for your style of travel.
  • That's why I purchased two Honda 2000i generators when my Onan died. It was cheaper than having the Onan fixed and now I have the option of taking two, one or none depending on what our needs will be on a trip.
  • I would assume this it the generator that needs to be pulled out for troubleshooting.
    With shops charging $150/hr doesn't take much to make it $600.
    If that is just starting issue, try SeaFoam first.
    Than my lawyer takes about $600 for 2 phone calls...
  • Ya it sounds like you have a new boat anchor. If it were me I would remove the unit and but a new Honda eu2200i. It is the same exact size as the older eu2000i it just replaced. Depending on the size of your current generator compartment it might fit in there for storage. If not you could use that space for a gas can for the Honda generator. Just some options.
  • Yes, unfortunately it is true of nearly all factory repair centers. It's seemed to me over the last 14 years of full time RV'ing that manufacturers don't want to bother with RV'ers or their little problems so ask outrageous amounts for very little work.

    I once got a formal quote on replacing the master cylinder on my Class A with Frightliner chassis at one of their shops and they came up with $2800 minimum firm. Ended up doing it myself...not an expert but it only took me 3 hours. Saved $2,200.

    There are shops around the country that repair Onan equipment more economically. Power Systems West in the Northwest region comes to mind. I used them for my Onan 7500 Watt genset when the front bearing ground itself to dust. Cost me $660. They are a chain and I suppose it would be up to each shop to decide if they want to work on RV generators though. That's a more specialized field requiring a different skill set just to get the dang thing out of the RV frame, or working on it inside that framework.

    I don't use mine much anyway (like most RV'ers) and if it dies, before I decide what to do about it, I'd certainly get a good grip on the symptoms in order to get a quote from 3-4 places and then decide whether it's cheaper to have it repaired at a competitors shop rather than a factory shop, pull the whole thing out and repair it myself (could require some heavy equipment like a big hydraulic tranni cart and a place to work with tools), pull it out and take it to a shop which would save labor costs, buy a new one from Harbor Freight (low cost but does need a bigger better muffler and probably an accessible gas tank installation so some redesign needed), or do nothing at all.

    Whatever you decide, they do have value to the next owner so it might be best to hang onto the one designed for the space in your RV's frame. As small as your unit is, it might be fairly easy to remove it yourself.

    Also, if you have a shop in mind to work on it, check them out on RVServiceReviews first.
