Fuse location on a KitchenAid Microwave

sounds like Touch pad/Keypad/Membrane Switch is bad or control panel is bad.
You can go online and using your model number search for parts, or have it repaired.
If your order parts do you have the skill, knowledge and tools to do job? You could end up throwing parts at it. Personally I would weigh the cost of repair plus the age of unit versus a new one.

Check the door safety interlock safety switches for proper operation. You will find them inside the cabinet.

If they have failed, the oven thinks the door is open and therefore will not turn on the heat. This is the most common reason for failure.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

The magnetron (the part that heats the food) may be ready to burn out. If you smell the burning, you should then unplug the microwave, open it up and see if you can determine for sure that it is coming from that part. Unfortunately even if I am right, it is almost more cost effective to just replace the microwave rather than replace that part. You can run this microwave till it dies if you want, but I would be ready with a new one.

Let me know how this works out for you.

Everything working is a real good sign. Most likely all thats wrong with your unit is a blown fuse. Go to http://www.partselect.com/MultiModels.aspx?ModelNum=kcms145j&SearchTerm=fuse&RefineSearch=0 and you will find the fuse. It's behind the touch pad with most all the other workings. Very easy to replace and cost only $11.76. It looks like an old round glass car fuse but it's made just for micro waves. It's most likely a 20 amp fuse. To get to it, take all the screws out from the back that hols the case on. once you have removed the case you will be able to locate the fuse. Good luck.

I would suspect the fuse, the magnetron's thermal cutout / thermostat, or the oven cavity thermal cutout / thermostat.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here (just enter your model number).

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download Kitchenaid owner's manuals and installation instructions here.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

check the fuse inside the unit, open the cover and locate the fuse, it is usually inline with the power cord. and the HV line.

bad control panel.. all power is routed through the control panel.. if your having a problem like that i would replace the control..

I'm assuming your correct model number is KCMS145JSS? You have a broken "release lever", part number AP3033332. It's reference number 7 on the exploded view diagram found here: http://www.appliancepartspros.com/sect/4/g/4/4g4rya32jj.gif You can order it by part number from Appliance Parts Pros here: http://tinyurl.com/gv383 If needed, you can download the owner's manual and installation guide here: http://www.kitchenaid.com/custserv/literature_search_results.jsp?searchTerm=kcms145jss If you need further help, please follow up.
