320s installing a microwave

gregp

Am considering replacing the air conditioner with a microwave for winter use.  Has anyone done this yet?  Any details would be greatly appreciated.  Thanks!  Greg

I’d really like to do this as well. If anyone has made this mod it would be nice to know what brand/model micro was used.  I only use the A/C in my driveway.  I live where it’s hot—I go where it’s cool! 😀

The opening for the AC unit is 16 3/4 inches and is comprised of not only the cabinet but also a metal bracket which supports the weight of the AC unit, so widening the opening would entail trimming the wood and modifying the bracket too.  The smallest microwave I can find is 17 inches wide, most are 17.3 inches or wider.  So the question is has anyone found one that fits?   Thanks!  Greg

I considered this last year.  The A/C cabinet opening is 16.75 inches wide (aluminum frame to aluminum frame).  The smallest microwave I could find is just under 18.0 inches wide (Westinghouse 700W).  I also considered a "Truckers" 12V micro, but was turned off by the many negative reviews. Here is the one I use in a slide-out wood cabinet over the driver side seating area:

Also, if you do find one that fits the A/C cabinet, insure sufficient venting by not blocking the A/C outside grill.

We are working through this now.  I have searched for HOURs to find a microwave with the right dimension, with no luck.  I settled on a Hamilton Beach 0.7 size from Walmart and our next step is to modify the box—as another member has already pointed out.  I’ll document the process in photos and post/announce once we make more progress, so far we only mostly removed the box for modification.

I have finished installing the microwave, it is a 700 watt magic chef from Home Depot with a 17.3 in width.  As @Tabaz points out it won't fit without modifications. After some thought I removed most of the vertical aluminum frame on the right side with a jigsaw, so now the microwave fits.  I then took a piece of plywood cut to size and using industrial adhesive and glued and screwed it next to the trimed vertical aluminum frame.   I then took a piece of sheet aluminum cut it to size and secured it to bottom and top of the aluminum frame and the new wood support with both adhesives and screws.  I then constructed a new maple frame for the outside of the microwave.  I can post a few pics of the frame support modifications if anyone is interested.

I assume by cutting into the frame, you do not intend on putting the A/C unit back in that cabinet.  After several months of using my A/C cabinet for extra storage, I doubt if I'll ever put the A/C back in.  Nice job!!

Nice! And the microwave can double as a small storage cabinet when not in use.  ;-)

Am not sure if I will  use the AC, but it was my intention to sufficiently reinforced the frame to hold the additional weight of the AC unit.

That looks great! Exactly what I want to do.  Nice work!

This is gorgeous! Can the 320 handle more than 700w when the T@B is plugged into shore power?

Yes, this is only around 8 AC amps.  But in actual use, the microwave is closer to a 10 amp draw.  A. 30amp Service is good for 3,000 watts.  The circuit breaker for the AC circuit, which is now being used by the Microwave, 
needs to be at least 15 amps.

Well I finished installing the microwave in my 2020 boonedock 320 s.I installed a 700watt master chef.Had to remove the cupboard and enlarge the door opening to fit the microwave.I used pieces of 2 x 4 to raise it up to proper height and also pcs on either side of opening to prevent the micro from shifting side to side.The frame work I made prevents it from coming forward.I ran the wiredown the wall into the inverter storage box and out through the air vent to pug it in .I used ebony stain to stain the new frame.
