    The
    first thing I would suggest is a hard reset. Unplug the unit for a
    minute or so. Then plug it back in, set the clock and try again.

    Let us know if the hard reset does not fix it.

    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises?

    Is it louder or quieter than usual?

How do I fix the key pad of a Kenmore microwave model 401.80084700?


I don't know of anyway to repair the keypad. Usually replacement (of the keypad/control console) is the only option. But you might want to remove the ribbon cable that connects the keypad to the control board behind it, clean it with a degreaser (like Fantastic or 409), dry it, and re-insert it, and then try again. (Remember to unplug the microwave oven first before you try that!)

Tip

Error Code "d" - Microwave does not heat


The microwave could be in "Demo Mode" - Check your owners manual.

In Whirlpool/Kenmore models this is indicated by a lower case "d" on the right side of the display panel.

Most/All function except the magnatron (heat) work in demo mode so you can can learn to use the oven without actually cooking food

To clear "demo mode" press the "kitchen timer" pad and hold for 5 seconds until the "d" clears from the display... you may hear 2 beeps.

If the microwave operates normally, but does not heath at all, then it can be the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, your model number did not return any result, contact the seller here to purchase parts. (here in UK).

Everything works... except the heat!


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

If you 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: http://tinyurl.com/yzjozk

You can probably find an exploded view by entering your FULL model number here: http://www.searspartsdirect.com

A full Sears/Kenmore model number usually has 3 digits, a dot, then 8 more digits, such as ###.########

If you think the problem is on the control panel, which we repair these nationwide for $39.95 postpaid.

Kenmore Microwave Problem


"d" may mean demo mode.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doen't fix it.

Kenmore microwave


If this has a controller that runs a microwave and an oven, then the problem F2 means a temperature related fault such as a bad temp sensor / thermostat or a defect in the control board. If it's just a microwave, then the problem is likely a failing keypad. In many cases, those can be replaced economically. If you repost with your exact model number (62622 is not a complete model number) then we can advise you further and more specifically.
