I recommend replacing it, as you said it is 7 years old and prices have dropped on the new microwave ovens making it more attractive to buy. The repairs with parts and labor will approach the cost of a new one.

E-11 Gas (humidity) sensor open error. Sensor unplugged, wiring or PCB open connection.

Since it's less than one year old, it would be fully covered under warranty. I'd really suggest contacting the manufacturer to get it fixed free.

But if you're discreet and careful, you can at least see if maybe the sensor has gotten unplugged from the circuit board. That would be a simple quick fix.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Otherwise, you can probably return it to the dealer since it's within the 30-day period and get another one.

So it's dead? (No display, no inside lights, no beeps?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
