You have a bad secondary interlock (lower door switch) or its mount is damaged or out of alignment.

We have the service manual for this model and have uploaded it to our site here to help you.

You will need the free Acrobat Reader to view or print it in case you don't have it.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you only need a switch, you can order a universal type here for $5 postpaid.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: can i get a display

The relevant service manuals are HTML clipboard here and here. hey contain detailed disassembly instructions.

There are three ways to get this fixed:

1. You could order a new power unit (lower board assembly) and a new upper display board assembly, solder them together, then replace your assembly with the newly assembled one.

You'd need the following parts:

DPWBFC167WRKZ CPU/LSI/display unit $107.07
DPWBFB094MRU0 power unit $53.09

Which can can be ordered from Encompass here.

2. This option is more difficult, but cheaper. You would order the upper circuit board assembly, desolder your old one from the lower power board, then solder the new upper board onto your power board.

You'd only need to order this part:

DPWBFC167WRKZ CPU / LSI / display unit $107.07

3. You could send your control panel assembly for repair for $39.95 with a one-year guarantee. Details are HTML clipboardhere.

Usually a mechanical issue with the door release assembly. Likely needs to come apart and parts be replaced. More often, it's cheaper to just replace the microwave as a whole
