MY rv ONAN MICRO QUIET 4000 HAS RUN OK YEARS. LAST SERVICE

Customer Question

MY rv ONAN MICRO QUIET 4000 HAS RUN OK FOR 8 YEARS. LAST SERVICE WAS IN SEP 2013. IT NOW WILL START BUT QUITS AFTER 5-10 MIN WITH A LOAD. GETTING A SERVICE PERSON TO COME TO A RV PARK IS DIFFICULT. PLEASE ADVISE AS TO PROBABLE CAUSE AND REMEDY. I HAVE SOME BASIC TOOLS AND MECHANICAL ABILITY.THANKS***@******.*** MODEL # *****

This can be caused by a lot of things - weak fuel pump, dirty carburetor, valves misadjusted, dirty air filter.

If it has not been serviced since 2013, for starters, it needs a good tune up, to include a valve adjustment.
