Question

How to prevent condensation from coming in a vented microwave


I have recently vented my microwave out my roof for cooking ventilation but now water is coming in through the top of my microwave to the inside of it. Who would correct this or what needs to be done to prevent this from happening ... It is a 4 inch expandable pipe running out the roof and the roofer put a vent with a damper on it

How to prevent condensation from coming in a vented microwave


Never heard of venting a microwave before. Why? I was unaware they needed any sort of venting whatsoever..?

Is it a natural gas microwave?

It should been install with a power vent. When microwave comes on the vent will open. I install one for olive garden 2 weeks ago. But if you don't use the microwave eveyday you just wasted money on the vent. Sorry but it is what it is

First off 4" is to small. You need a 6" pipe. It also must be insulated in the attic. It's not code to run it in flex pipe. It must be rigid pipe and elbows with no screws.

Interesting!
I imagine that either your vent would need to be small enough to keep the steam from condensing (probably impossible given the low temp's involved) or power venting that is strong enough to force the steam out or the more practical solution might be to put a collecter on the vent just above the microwave if you have a drain option nearby.

There are combination ovens (microwave/convection) readily available in the market place today. Out.

Dawn

I don't know to many people up that way in the business. Your best bet would be to get references from family and friends.

Good luck
