Floor Vacuum system not working

One piece of info for those with Cummins L9/ISL engines. These has an inlet grid heater that will pull chassis battery current when the key is first turned to the run position (wait for the yellow coil indicator to go out before cranking), but this grid heat will continue to cycle on and off for 2 minutes after engine start if the ambient temperature is below 65F. After the alternator starts regulating voltage above 13.2 volts, each time the grid heater cycles on, it pulls the voltage down to around 12.5 volts.

On my American Coach Dream, if I try to run the slides with the voltage below 13.2, the slide controllers will lose their programming. Don’t know if the Entegra coaches have similar issues with low voltage when the grid heater cycling.

Regarding this thread, if you run the block heater for 30 minutes before starting, the grid heater won’t cycle. The voltage comes up and stays well above the 13.2 volt minimum I need to keep the slide controllers behaving.

Those with the 605 Cummins, never mind. Those engines do not have the inlet grid heater.

Yes, the block heater and the floor vac system is on the same circuit. I was told that my warranty ended in Feb this year. The cost to replace the block heater is $1000+, why do I need one I don't use a motor home in extreme weather and only travel in summer weather due to my wife's health. We don't travel farther than 500 miles from our home base. She still wants the floor vac system. So had the tech unplug the block heater. Thanks for all the suggestions. The Cadman!

I bought my 22 Aspire 40P in Oct 2021. Upon delivery the tech found dirt devil would trip the breaker every time. As of March 9th 2023 finally fixed. I recommended testing the breaker but I am not a rv tech
The dealer first replaced dirt devil still tripped breaker. Then replace outlet in the basement (of course unplugged block heater) didn’t work. then ordered new Romex. finally they decided in February 2023 to replace the breaker. VOILA! It finally works after 17 months later and 7 trips to dealer. I say the whole RV mfg process and Warrenty procedure is broken. I think dropping your rv off to diagnose pick it up take it home and wait 2 month for a simple part is stupid. I love my RV hate my dealer and the inconvenience of waiting 17 months for an idiotic fix. That was just one of the dozens of ghosts and goblins that needed fixing
