Where is light bulb in model MMV5207BA/BC - Whirlpool Microwave Ovens

Question edited for a hell of a lot more clarity.
All question need 'make model (what it is)' please, first 3 words.

It literally could be anything. The only thing you can try is a power cycle or check the back for a fuse holder near the mains lead.

If there is no power to the display/clock then your control board has failed. Check eBay for a replacement.

Sounds like the magnetron tube is no longer working. Check for a bad fuse but if fuse is good, then .......... Sorry.

mmv5207ba/bc microwave 0 button fan on button does not work all other key pad buttons seem to work

MY MMV5207BA/BC starts running for no reason. We have to raise the door by the handle to get it to stop running. Is there any solution for this problem?

90 percent certain to be the magnetron

From the owner's manual:

Cooktop Light/Night Light

On models JVM1850, JNM1851, DVM1850 and EMO4000, replace the burned-out bulb with a 120 volt, 40-watt incandescent bulb (WB36X10003), available from your GE supplier.

On models JVM1870, JVM1871, JVM2050 and JVM3670, replace the burned-out bulb with a 120 volt,
20-watt halogen bulb (WB36X10213), available from your GE supplier.

To replace the bulb(s), first disconnect the power at the main fuse or circuit breaker panel or pull the plug.

Remove the screw at the left edge of the light cover and push on the right edge of the cover to open.

Be sure the bulb(s) to be replaced are cool before removing.

After breaking the adhesive seal, remove the bulb by either gently turning (for models JVM1850, JNM1851, DVM1850 and EMO4000) or pulling straight out (for models JVM1870, JVM1871, JVM2050 and JVM3670).

Hi,

Microwave Oven Basic Troubleshooting Tips

A 20W, 120V replacement xenon halogen bulb with G8 base can be purchased from Lowe's.

E13 is usually a bad door switch or door switch mount.

The first step is to unplug it from the power outlet for one minute, then plug it back in and try it again.

If it still fails to heat, I would check the door switches and door switch mounts.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

NOTE: There should 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.
