Last year we had a handyman vent our GE spacemaker to the outside;
howerver, the vent is not pulling much air. It is pushing a lot of air
out. We had the same model in our last house and it sucked air like
crazy. Any thoughts before I go an take the microwave down and look at
There are 2 ways to vent outside on those units: to the back and on
top. Whatever opening is not used, usually there is a blank plate on
it. Is it possible the blank plate was not put back, and maybe thats
why you are losing suction at the bottom? The only way you are going
to know is when you take down the unit.
Also make sure the blower motor is oriented correctly depending which
way you vent out. There are 3 ways it could be oriented for: top
venting, back venting, and self venting. If you look on GE's website
in one of the owners manual it will explain more in detail. But then
again, you said it was pushing air out, so maybe it is correct, but
just check anyway.
Sorry I am just getting back to you, byt thanks for your help. I am
going to look at it this week! One thing I noticed, is that if I put
towels over the vent facing the kitchen (at the top of the microwave)
I get some suction. So something is missing inside, for sure.
It appears that you experienced the very same issue I'm having. The output vent
blows a bodacious amount of air. The intake over the oven, however takes in
almost nothing. The vent into the kitchen is also sucking in just a wee tiny
The fans are oriented to blow outside via the back of the unit. According to the
installation manual, everything is properly in place.
What was your solution?
Yeah, I realize this is very old. Unfortunately it is the only information I've
found that remotely describes my situation. In fact it exactly describes the
symptoms I'm experiencing, and I just can't figure it out. I think maybe there
is a missing piece or something. Anyhow, if Daniel figured it out and he gets
email notifications at the same place he did 5 years ago, there is a chance he
can help me out... Or perhaps somebody that notices this thread has been brought
back to life will have some insight.
If it were me, unless I could see exactly how it's connected,
vented to the outside, etc, I would take it down. They are
only held by a few screws. I wouldn't be surprised to find
that it's not really connected properly to the outside vent.
I'd compare what I see to what the manual shows.
