To check the internal fuse. Unplug the oven, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. It looks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it for continuity with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.
Hope ya fix it!

I have a Kitchenaid microwave model KCMS145JSS-0. It is no longer heating. What can I do to repair it?


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.

I have a microwave model #kcms145jss-o. everything works on it, but it will not heat. Thanks Ray


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.

I have a microwwave oven that turns on but will not heat. It has never worked. Is this an install problem or unit problem? KCMS145JSS


You will need to check to find out if the microwave has all the power coming to the critical units.
If the latch switch is active then the turntable and fan must work but if there is no heat, the check on the thermal cut off switch fitted on the side of the cabin , if faulty. , the pwoerr will be cut off to the magnetron. Check also to confirm that the high voltage capacitor is working and not shorted or open.
The relay on the main boarrd also must click to switch on or else the relay or relay drive must also be checked out.

When I turn on the micowave; smell somthing burning


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.

I have a Kichenaid microwave Model # KCMS145JSS-1 No lights, no readout, completly dead. Power source checked and o.k. Any thoughts?


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.

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

Broken Microwaive Door


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.
