Kitchenaid MW/Oven combo Mod#KEHC379JWH05 Door error?

11 posts in this topic

This unit wasn't cooking and had the magnetron, capacitor and diode changed. Then it gave a door error and wont start? I checked all the door switches and the seemed fine. What could this be? Thanks.

Check the 30 amp cartridge fuse located behind the control panel.  On some combos a shorted fuse may cause the microcomputer to think there is a door switch fault.

Haven't seen any fuses short but I guess fluke happens!

I replaced the buss fuse but it tested good, it toned out. So did the door switches. That's why its confusing. Ive got the service manual so I'm gonna make sure everything is connected correctly and then if its all good I guess bad control board? One thing, the technician before me used a oven dolly annulled on one of the light transformers wires, so its kinda loose, that wouldn't cause any issues right?

Doubtful.  Door switches might check good but may not be actuating properly.  Double check the switch located upper left corner of cavity.

Not the microwave fuse inside the microwave, but the fuse on top of the oven behind the control panel. It's in series with the door circuit. 9 out of 10 times when you get the door error.

Rechecked every door switch, replaced all ew ones with new ones. Checked wiring of cap and mag. Tested all cavity thermostats and all check good. Still with a door error microwave wont start. Could it be the control or touchpad? Ty for all your help.

Just to confirm, the plastic mount holding the switches is properly secured and not loose correct? Also, the door switch mounting tabs could be broken...

 

Are you getting light when door open and light turns off when closed? If so, probably bad board per the service bulletin.
