Oven rarely comes up to temperature Maytag MGS5870ADC

Since I've purchased it (4+ years) my oven rarely comes up to temperature. I can sometimes coax it by leaving the stovetop burner on but this could be coincidental. With the holidays coming I'm getting anxious. If I have to cook outdoors too often my wife may just leave me there ;o)

Common problems and solutions Q - My microwave seems to shut off every once in a while, what might be wrong?
A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.
Use an old tooth brush to help clean off the grille area.

Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
 Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
 Q - My microwave went dead when I opened the door ( same problem as closed the door ).
A - This often is a stuck or faulty door switch and it has blown the interior microwave fuse.
 Q - My microwave is completely dead.
A - House fuse has blown or interior fuse inside the microwave has blown ( usually a part inside the microwave makes this fuse blow ) Sometimes a bad fuse holder inside the microwave cannot hold the fuse tight enough and the fuse will blow as well. 
 Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.
 Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section
Q--Microwave stopped working while cooking. Replaced a 20AMP fuse.
When the cook cycle starts, microwave makes a groaning noise and stops. It loses power since the fuse is blown.
Solution: High-voltage capacitor shorted. Replaced it and microwave works fine.
Its located behind the fan underneath the high-voltage transformer.
Remove the vent fan hood
Remove the display control panel by removing the screw
Take pictures of all the connections behind the control panel.
Unhook all connections
Remove the connections to fan
Remove the fan
Remove the screws and connections for interlocking switches.
Make sure the high voltage capacitor is discharged!
Remove the high voltage capacitor and replace
Retrace the steps and put everything back.

    Q - I burnt something in my
    microwave and now it is!

    A - The fuse inside the
    microwave may have blown, but more commonly the flame/oven thermostat has sensed
    the over cooked food and the flame/oven/cavity thermostat has opened up - Info on that

    Can my microwave be used for more than
    making popcorn and heating up coffee?

    Yes! It is possible
    to prepare an entire gourmet menu in your microwave, like Fancy Poached Fish
    Filets with a Lemon Shallot Sauce, Citrus Rice and Lime Carrots and Sugar Snap
    Peas. Pat Cohen has developed a unique microwave cooking method called the
    Synchronized Cooking Time Line©, a clever little
    graph that outlines the times and sequences for each step in the preparation of
    recipes. This time line makes microwave cooking visual, simple, and almost
    foolproof. The cookbook is called on beyond popcorn… Maximizing Your Microwave
    Using the Synchronized Cooking Time Line© and
    can be found in our cooking accessories section. We highly recommend this book -
    it is full of over 200 delicious recipes that will delight and amaze your family
    and friends.

    Why do some foods come out with tough

    Because the microwave energy
    is beamed into the interior of the microwave and then dispersed by a metallic
    "stirrer," the pattern of the energy can be fairly consistent, rather than
    completely random. But this pattern sometimes causes certain portions of the
    food to overcook (creating tough spots) and others to undercook. A microwave
    oven with a carousel is far better at cooking the food consistently--the pattern
    becomes quite random while the carousel is

    Why is there a glass tray in the bottom of
    my microwave?

    The glass tray has two
    proposes. It catches spills. It also raises the food off the floor of the
    microwave so that the microwave energy can reach the bottom of the food,

    How can I tell if my unit is leaking
    microwave energy?

    You can do a fair job with
    the inexpensive sort of tester that you can buy from a hardware store. To get a
    more accurate reading, contact a qualified appliance repair

    Are the microwaves in my oven

    Not usually. As long as the
    microwave oven door remains closed and you make no direct contact with the
    inside of the oven while the oven is on, the energy is safe. If you were to
    operate the microwave oven with the door open, it would be dangerous.

    Can I make beef jerky in my microwave

    No. To make beef jerky takes
    an extremely slow drying and curing process.

    Where can I get an owner's manual for my

    From the manufacturer of the
    microwave. See our "Locate and Order Parts" section.

    Why do eggs, potatoes, and other things
    explode in the microwave?

    Microwave energy penetrates
    foods much more deeply than conventional heating does. The water molecules
    inside the food heat as quickly as those on the outside. And water expands when
    you heat it. Eggs, potatoes, and other things with shells or skins explode
    because the expanding water has nowhere to go.

    Does prolonged exposure to microwave energy
    cause health problems?

    Some studies indicate a
    possibility for health problems with prolonged exposure to microwave energy. But
    most research has shown that it's very natural to be exposed to low-level
    microwaves--we get that exposure even from the atmosphere--without any adverse
    or lasting effects. Microwave ovens are required to meet very stringent federal
    government guidelines for leakage.

Steps to check element. TURN off breaker that feeds oven. Unistall bottom element in question. With a continuity tester see if element has continuity. If it does not then element is bad, replace it and turn on breaker. If it does you need to call a technician because the next step requires voltage testings that can shock you if done improperly..

When using oven F3 or F5 comes up on the digital display and it beeps. Sometimes it says err on it. Very frustrataing, use my oven a lot.

Replace the temperature sensor first. It may solve both problems. If not,the clock will have to be replaced too.

F3 or F4 Open or shorted oven temperature sensor Replace oven temperature sensor F5 Hardware and watchdog circuits disagree Replace clock assembly (also called the ERC)

Top burners often wont light if oven is already lit

Hello and welcome,
If your range has electronic igniters, then you seem to have one or more bad igniters on top of the range if you have a pilot range then you have a gas restriction or clogged orifice tube.
Even if they make the click noise while trying to light they may not get hot enough to draw the gas on a constant speed!

This will need to be diagnosed hands on at your location.
But this is the fault!

Thank you for using fixya.

We had the same thing happen and had the Atco Gas company come out to look at it.  Our regulator was not working properly which caused CO to be relased.  We were told that the problem could be fixed for about $250-300 (CAN.) including parts and labour.
