Over-Range Microwave seems to stop heating when gas range is on

[ts8586]

I have a new Maytag microwave (MMV1175JZ) installed in November, and twice now, it seems to stop heating, even though it runs. Both times, the gas range below has been on (burners and oven). Also both times, the microwave works fine for about the first 10 minutes. When it stops heating, the power on the microwave seems to increase, like a fan kicks on. After we turn the burners off and let things "cool down", the microwave seems to operate normally. Also, we haven't had any issues when operating the microwave by itself.

I already have a service call booked with Maytag (3.5 weeks out!) just in case this is an issue, but our previous microwave was at least 16 years old, not sure if this a common thing with newer microwaves. The Maytag manual and their customer support is basically useless.

Has anyone heard of anything like this, or does it sound like a defective microwave oven?

Are you operating the vent at the same time this is occurring, and if so, is the vent just recirculating, or venting to the exterior?

What is the height of the MW above the appliance?

There is no exterior vent, it just re-circulates. I would have to get an exact measurement later, I'm not home now.

Thanks, I ask because it sounds like a heat sensor, in the MV has failed, or is faulty.
We also have an MMV model, and haven't had a difficulty similar to yours, however, it is our practice to prepare anything requiring a longer time, in the MV, than 7-8min, that the gas range is more economical

Just our preference.

Besides overheating the MV I can't see a link between an electric MV & a gas range.

Your MV might already be ruined.

I believe the problem has been solved. The installer left some plastic covers on the top vent, so only a little air was escaping. I actually had to stand on a chair to see the "please remove" on the covers! Tested again the same way it failed before, and had no problems.

If it fails before its time, think of that careless installer.

Yeah, definitely. Hopefully it'll still be under warranty.
