There has been quite a bit of discussion on various Facebook groups about scorching walls behind unvented microwave / convection ovens. I just pulled ours, and we indeed have scorched walls. I couldn't find a similar report in the Appliances section, so here goes!
Due to an accident, we had our driver side wall replaced in September (great support from GDRV service, especially Val). So this wall is only 5 months old!
Have any of you faced this? If so, what mitigations have you put in?
GDRV-Emily GDRV-Megan Is it possible to retrofit an external vent in this unit? I remember hearing somewhere that there is an aluminum frame member where the vent would need to go, but I don't think it was authoritative. Does GDRV have any remedy "in hand" that you recommend to or perform for owners experiencing this problem?
Even if an external vent could be put in, it isn't clear to me that would fix the problem, as the hot spot is not near the vent exits, and venting is currently happening through the front top of the unit.
I'm currently considering putting an aluminum or steel heat shield back there, but to be effective that would need an air gap on both sides, and there is very little extra space behind the unit (below, you can see where the back came in contact with the seam tape).
It is interesting to me that the Furrion unit in a friend's rig has an extra metal strip screwed onto the bottom of the back with seemingly no purpose except to shim the unit away from the wall approximately 3/16 inch..
I'm considering shimming the mounting hardware to give me approximately 3/8" clearance behind, and putting a sheet of metal with ~3/16" on either side, and also allowing air to come in through gaps in the bottom shim to create a chimney effect. I'd dearly like some thoughts about this approach.
This much scorching in only 5 months! The loose 12V wire is now neatly strapped across the batten at the top back, out of the way. Note that the seam table has bubbled, and the glue is oozing out. The seam tape came in contact with the back of the unit. I need to fix this somehow; still considering options. Some people have reported simply replacing the unit with another brand, but who is to say that wouldn't have a similar problem?
Thanks for any thoughts!
