Cut the hole in the vent yourself? I don't understand. I'm pretty sure my builder provided me with an OTR vent, and it was ready to go when the appliance guys came to install the microwave. Can you clarify? Or ask the builder for clarification?

I asked them and they said we would have to have them cut the hole when the OTR microwave was installed and they dont install the microwave. Kimdee24 - I can not believe you have built multiple houses, this is so irritating!

My builder didn't install my microwave either (because it was a different microwave than the one that they would have supplied if I went with the standard appliance package). As long as the vent is there, it shouldn't be an issue for your appliance installer. Though I'm still unclear about "cutting the hole", I don't recall my appliance installer having to cut anything but maybe I've forgotten. Unless they mean cutting the hole through the cabinet for the vent for the microwave -- that would make sense because each microwave has a different configuration, placement of the vent.

Do you have an appliance installer?

not yet - I probably will order my appliances sears, the builder gave me the number and said I would get builder prices....but I havent ordered or priced anything yet. I believe they said they would deliver and install.
