The keypad on my built-in microwave model KCMS145JSS-0 has stopped working and displays a running set of numbers: 1121, repeatedly. I tried holding the cancel button for 5+ seconds and thi9s causes

Holding cancel key down to re-set, causes humming noise which stops on it's own, but numbers 1121 continue to scroll on display pad.

The 22 seconds is the giveaway.

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

I checked the 200 amp breaker box and found that the screw for the wire going to the breaker for the microwave was already as tight as it could go. So, it appears that there is nothing more to do with this and I don't think I'll have any more problems with this microwave.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

You can order Samsung parts here.

You can find your nearest Samsung-authorized service center here.

To find out if yours was recalled, please call Samsung's Service Division at 800-932-3837.

It sounds like your membrane keypad may be shorted.

Unlockmy lg microwave oven


As with most situations, it depends on the model number, but try this:

To set child lock:

1. Touch STOP/CLEAR pad.

2. Touch and hold 0 pad more than 4 seconds. LOCKED will appear in the display window and oven will beep twice.

To cancel child lock:

1. Touch and hold 0 pad for more than 4 seconds. LOCKED will disappear from the display and the oven will beep twice.

Whirlpool is conducting a safety recall on the Kitchenaid KHMS155L series (and similar models under other brand names) that display the F2 code or have been observed self-starting.

To obtain free replacement of the control panel, call Ava at Whirlpool: 1-866-640-7146, extension 6337. She will want your complete model and serial numbers and a phone number and address where you can be reached. She will arrange for A & E Factory Service to contact you to set up an appointment to come out and replace the control panel at no cost to you.

Built-in microwave: display works but oven does not.


You didn't mention your model number. If I knew that, I could check to see if it's one of the models subject to a recall for failed membrane keypads.

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.

Microwave oven will not work


Seems like I've answered this before, but the MR5493G is subject to a recall due to defective keypad (membrane switch) and can be seriously dangerous.

See: www.allworldauto.com/recalls/samsung_microwave_mr5493g_recalls_1420-10455-1.html

The MR1032BB is also under recall. See: www.motorbeat.com/model/samsung+microwave/mr1032bb/

If neither is covered under the recall, you should be able to order new keypads here: http://www.samsungparts.com/search/search.asp

If not, we'd be happy to help you. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk
