My builtin kitchen aid mw keeps giving me door error. I checked right two primary and monitor switches and they work fine. How do I access left switch. There is vey limited access without taking everything apart
Hi.
There is a 20amp fuse behind the control panel on the right.
Most likely it’s blown W10017410

Fuse was blown. I replaced it and it still gives me same door error.

What’s next ??
Hi.
Most likely the fuse is blown again. You need to check the door switches with the multimeter with the door open and closed.
You can get to the left side switch by pulling the microwave out for few inches.

I checked the fuse and it is good this time outside as well as continuity between terminals as installed. I did check the right two switches in open and closed door position and they seem to switch NO and NC correctly.
I have MW pulled out and can see the left side switch holder but and probably can pull out from top but I am afraid I may not be able to put it back. It has circular white plastic flange facing inside of the mcirowave.
Hi.
To get to the secondary interlock switch with the MW out take out 6 screws and remove the left side cover.
Did you remove one wire off the switch while testing?
Did you check the other fuse ( it inside the MW on the right) and is smaller then the first one.
Simon.
Hi,
For your convinience I attached the instructions with a few pictures on how to remove the microwave from the oven cabinet. Hope it will help.

Hi Simon,
May be I am not checking switch properly. Can you explain what you mean by taking one wire off ? I am following Tech Sheet, with schematic. i.e. Door open should have continuity between BR and R/BK and door closed between BU and R/BK.
Also, I checked first fuse (big size, 20A) as per instructions earlier. I also checked the second small 15A inside right top (inline with 20A in schematic).Is that correct ?
I have not checked secondary switch yet, I will open the side panel.
Thanks for your help.
Thanks Gene. I was able to pull out MW out. Good instructions…I am still having problem troubleshooting Door error.
Hi.
When you are checking continuity/resistance of any part at least one wire should be removed from it or the reading will be incorrect.
If you are sure that all the switches and fuses are good - replace the control board [part]8302346[/part]
If that won’t solve the problem you can return the control back to APP.

Hi Simon/Gene,
New problem ! I was able to fix the door error by replacing the fuse. But I guess I must have wiggled control panel too much. First I lost connection to easy minute button, did not work. So I tried pulling out flex cable connector and putting it back. Now my none of the keys work. Is there any trick in putting this ribbon back in the connector ? I tried aligning the circuit traces to the connector contacts and inserted in and then clamped the top black piece. Please help !
Hi.
The flex ribbon must be in all the way.Sounds like you are putting it in correctly. Try to wash the edge with isopropyl alcohol, dry it and put back.
Check the ribbon for cracks, make sure the right side goes in.
Simon.
Thanks Simon.
I will try cleaning and putting it back. Couple of quick questions meanwhile,
- There is only one way to put it in. What do you mean by right side in ? Did you mean right side of the ribbon (not left) is inserted properly ?
- If there is a crack. Is there a replacement ribbon available ? I hope I don’t have to repalce whole keys membrane. I suppose I have to disconnect from both side. i.e. from switch membranes and control board. Correct ?
Thanks for your help.
Hi.
What I ment is make sure the ribbon contacts are touching the contacts inside the plug.
Unfortunately the ribbon is a part of the membrane 8302669

Hi Simon,
I cleaned and put it back. No sign of any circuit traces break… No responses from any keys…is there any fuse or something that disabled the key board ? Is there anything else to check before I replace entire membrane panel ?
Thanks for your help.
Hi.
Try to replace the membrane first. If that not going to fix the problem - replace the control board.
You can return unused parts back to APP even if you installed them.
Simon.
It appears that membrane panel i got is incorrect. It does not have standoffs threaded posts to mount control board at 6 locatios. This 8302669 panel does not have any standoffs. Shouldn’t it be 4452323 ?
Hi.
According to the several websites this is the correct part number 83026669.
It could of been mispackaged, but it is the correct one.
