converter replacement

July 16, 2015, 03:17:11 pm

In a 3300 Grand Villa front engine gas. The old Magnetek converter failed and I have new Powermax 75 from Randy @ Best RV. The orginal location was in sewer valve bay and was exposed to some road spray and terminals were badly corroded. Randy says to relocate to dry space. Easiest place is under the bed next to the transfer switch and breaker boxes. I wonder why it was not there to begin with. Is there a reason not to place it there? There is plenty of room and wires are already there. Any advice? Thanks, John

If you hear it humming while you are trying to sleep on the bed maybe it is because it doesn't know the words?

Is there adequate ventilation in the location you are considering.  Converters do produce heat and need to be able to dissipate it.

The space under the bed is mostly the fresh water tank, but there is open area 12 X 18 X 60 inches with only water pump and transfer switch. Also wires and 12V & 120V breakers/fuse boxes. The only ventilation is a 12"X12" tambour type door. Another plus is the installation and access will be easy.

May be the humming is loud enough to drown out snoring??

Thanks,

John

All the old converters were noisy now that it was brought up.  Had to rubber mount them in the valve compartment.  Obnoxious now that I remember.

No idea on the new ones

Just to report back on this project. The under the bed location is working fine. I mounted the new converter on a thick high density neoprene foam pad  right behind the 120V panel. In retrospect rubber isolaters like those in the Kool-o-matic I am working on now would be simpler instead of the pad.  Also relocated the outlet for the converter there too. The new unit is very quiet and the wire runs are significantly shorter. Corrosion issues should be improved from the original sewer valve bay spot. I left it on for a couple of days in 90 deg. weather with no heat build up noticeable.

Thanks for your advice.

John
