We see this a lot. The problem is almost certainly on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The 665 prefix on your model number is Whirlpool, but I haven't found the code "d" listed yet.

Can you set the cooking time?

If so, what happens when you press Start?

I'll post back if I find the codes or if you have other info and I can help further.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.

There is an internal fuse, plus one or two thermostats or thermal cutouts.

You can probably find an exploded view by entering your FULL model number here: http://www.searspartsdirect.com

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

You can download GE owner's manuals and installation instructions here.
