Need wiring diag. for Panasonic H264wf - Panasonic NN-H275 Microwave Oven

Contact the manufacturer directly to request the diagram.

check your switch at door assembly

May be a door switch problem, or may be a control board problem. You might even have a shorted wire that goes to the turntable motor. (I have seen 1 of the wires get pinched and cut by metal guards or guides that were meant to keep the wires in place.) You can remove the screws from the bottom of the microwave oven, and drop the bottom panel down to checked for pinched wires. Unplug the microwave first before you do that.

You woll need the model number too.

kindly check door lever

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.
That would be a problem on your controller assembly, which I can repair for $54.95, which includes insured return US shipping.
I would need to know the full model number from the tag on it, and the FCC ID number can be helpful, too.
Please contact me directly for full details since FIxYa doesn't always inform us of follow-up questions.

If it stops after 7 seconds, it has a problem with the inverter.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor. But I don't think that's the issue here.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

Hi!
I read your comment about needing to remove the control board to inspect it for damage. Looking at the diag. below, all you need to do is open the oven door and remove the two screws (#2 on diag.) fastening the brackets that hold the board in place and you can take it from there.

Refer to the diag. below If it was me, I would start by turning the breakers for both ovens OFF, then, in getting someone to help me pull the oven out, disconnect the power cord and check the power circuit protection devices like the fuse #4, located above the fan and the power board #25 also located on the back of the unit. Before replacing the blown fuse, inspect the wiring, If the unit is mounted over an oven that was in the Self Cleaning Mode that reaches temps. of about 500 degrees, there is a chance that a wire's insulation melted and shorted the unit.

If it's a Panasonic commercial model (NE1757,NE2157), check the two fuses first. If one is blown, first take a look at the upper door switch to be sure it's activating. If that and the bracket look ok, you most likely have one of the following parts that need to be replaced...
Fan motor, HV Transformer, or Magnetron tube (or a combination of). Also look at the two white wires going to the middle relay on the lower relay board. If they're burned, you'll need this board and possibly one of the above parts as well.
