Whirlpool Washer KHMS155LSS4 Parts List

Per the tech sheets (page 8), "F2" error code means "Keyboard failure". Recommended by the manufacturer to replace the touch panel first and, if it would not solve the problem, then the control board has to be replaced too. Not the best recommendation but we have to follow it.

- The part number for the touch panel (aka a membrane switch) is AP3130765

- The part number for the control board AP3130764

Here are the break down diagrams for the Kitchen Aid microwave Model KHMS155LSS4

Hello & Welcome to FixYa

The problem is with the fuse or the high voltage transformer that is bad and needs replacement. Replacing the fuse will cost you under $100 from a professional and getting the transformer replaced will cost you around $200. As the unit has very high voltage inside so we don't recommend that this should be done by the user. Please get back to me if you have any other questions.

Maybe. You can get a fuse here: http://www.amiparts.com//A33A673631FA4E01ABD536DEFEA76A01.asp?pcs_key=A31D300EB99A4D17A25D1D3529D26562

Check your plug and change the fuse there also.

You might need to rechange the 20 amp 250v fuse behind the control panel again due to the recent spark.

If none of this works then i'm afraid a certified technician needs to check the power packs and boards

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open. Then when it cools, it closes the circuit and allows power through again.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again. If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

There may also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.
