Main oven wont heat


Thank you for your post, Allison! I understand that you are having concerns with your microwave oven heating. This could be because of several factors, such as: loss of power to the microwave, a displayed error message or a faulty magnetron. Please ensure that your household power circuit breaker is not tripped and that your appliance is not displaying an alpha-numeric error message or code on your control panel. If you notice an error message please comment and let me know so that I can help you further. Otherwise, if you do not notice any errors and have sufficient power you are more than likely experiencing a faulty magnetron. The magnetron is the sole component that allows the microwave to heat. This is not a typical do it yourself repair so I recommend contacting a professional to confirm this and complete any necessary repairs.

Thanks,
Chris

Mu accuwaave makes a short noise intermittenly while trying to heat


Hi,

Is your microwave oven set to full power when the intermittent noise occurs?

If it's set to a lower power rating, then the noise you describe sounds perfectly normal.
At a lower power setting, the device which creates the heat or microwaves, called the magnetron, switches on and off intermittently so that the food etc. is not cooked too fast.
This is quite normal & you should only be concerned if the noise occurs while the microwave oven is set to full power.
In that case you will have to have it checked out to see what the cause is.

Best wishes,
Graemevm

Microwave model MMV5207BAW won't power up when pluged in. Outlet has power but microwave wont power up.


Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Kenmore Microwave model 721.80019 does not heat


Hi

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. As there was power loss due to storm so I believe it could either be the the high voltage circuitry, or the circuit board . To resolve this problem, you need the assistance of a qualified appliance repair technician.

Please do rate the solution as FixYa and revert for further assitance.

Thanks

Power cord


If you are referring to the main power cord then you should be able to purchase one at Home Depot/Lowes of most local hardware stores... make sure you get the current rating off the tag on the appliance.. 15Amp or less can use a cord size of 14 gauge.. you should use a 12 gauge for any appliance requiring up to 20Amps ( in your case ..1100 watts minus losses within the system should allow you to use 14 gauge power cord.)

Microwave oven start button not functioning


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.

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

If you or a friend 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
