Ours has issues. It's about halfway over the front burners and so anything on the stove that has steam makes it steam up, even with the fan running FULL blast.
The light under the microwave burned out early in our rental, and the landlady's husband says there's no light at all (he also managed to replace our fridge's water system with a wrong, doesn't fit, filter and wouldn't listen to me about it, so we don't get filtered water through it and who knows how ice is being made but it is).
A few months back, something happened in the microwave where the fan was on ALL the time when it was closed. I'm really sensitive to that sort of noise and it was keeping me up at night. We had to start taping the front of it open (can't just have it wide open because one of us would smash into it I'm sure).
They got some maintenance guys out here to fix it (the washer went floopy at the same time), but just 2ish months later it has happened again. We're so disheartened about how it was taken care of the last time that we're just living with it for now...it happened just after paying rent in June and we only told her about it in July (we've been tenants of hers for years now, she knows that we normally report things to her immediately, we all adore each other...so I feel that she isn't going to hold the delayed reporting of this ONE thing against her). Alas she's on a nearly month long vacation (to WDW I believe) and can't do anything about it until she's back. So we're back to taping it open.
And now the light in the washer, which is part of the thing they changed out, has burned out. It stays on and heats up if you leave the washer door open, which you have to do with the HE front loader b/c if you leave it closed it grows mildew... Can't win!
Anyway, I think it's a problem. I want to rip it out and put in a proper fan (I don't even know where this vents to...I think it just blows right out the top front of it actually, and I don't get the point of that) and just use some counter space or just not have a microwave anymore. It's peeving me THAT much.
