3 Most Common Microwave Problems  |  Fuse, Door Switch, F1E4 Error

okay today I’m going to show you how you
can easily fix the three most common problems that go wrong with a microwave
the first one is the microwave is completely dead the screen doesn’t turn
on the second one is a combination where you might see a door error the the light
might stay on the fan might stay on there’s something wrong when you open
and shut the door the third one is a little more complicated and that is the
F 1 e 4 error so let me start with first the easiest one and that’s the microwave
is completely dead it won’t turn on so let me show you how to fix that so your
microwave is probably different than mine but all of these repairs will be in
the same general area and the same general fix just for reference mine is a
two year old whirlpool microwave I heard I read a lot of comments about a two
year old microwave breaking just like minding so first let me show you how to
fix the completely dead microwave and step one is to unplug it now I’m gonna
have to remove this panel and this cover again yours might be a little different
but generally you want to get to behind this panel here so you remove the two
top screws and this panel comes right out now on the Whirlpool microwaves the
fuse is located behind this cover you remove this panel there’s nothing
holding it in if you look right here that’s the fuse that is the main fuse
and we knew ours was bad because it was all burned if your microwave is
completely dead won’t turn on 99% of the time just replace that main fuse and
I’ll put a link to in the description below of what fuse to get but you could
go to any hardware store and just look for appliance fuse and just for
reference it’s 20 amp and 250 volt okay this next fix is the second problem you
might have and that’s a door issue where you might see door air it might stay on
the light or the fan might stay on when you shut it issues like that and that is
a problem with switches there are three switches behind here first we have to
get jump so let me show you how to do that
mine there’s a screw on the top you lift up and you could pull this right out
there’s wires behind here so you might want to take a picture with your phone
to know where they go but they only go and plug in one way
then there’s two more blue wires this is a ground wire right here once that’s
removed you can use a screwdriver and remove this plastic cover and the wires
plastic and it pulls right out now there’s two spots where it clicks in
you can see on the microwave there’s two little clicks here and here and those
lock in and there’s three switches now you have to remove two screws on the
front to get the switches out on the top there are two switches one on either
side they have names like FD 62 FD 61 things like that it doesn’t really
matter exactly what that code is you just have to know some key things some
switches are normally open and when they’re clicked they close some switches
are normally closed and when you click they open and then there’s one that’s
either open or closed that will trigger either way so if you’re never sure you
can always buy the 3-way switch it will always work it depends on where you plug
it in that’s the key you can tell just by looking at the switch where the wires
plug in and you could tell if a switch is pretty good
typically by listening if you push in the little button you can hear it click
when ours broke we had a door issue it said door and then the fuse blew and
when I took these switches all apart one of them was completely fused it wouldn’t
click in and that was the one that was wrong we ended up buying all new
switches but I found out later that that was the one that was wrong and you can
actually take these apart these switches are pretty open easy to take apart and
you could see that the metal plates were fused and I forced them apart and it
actually could have started working a menu reused so again I will put links to
all these switches down in the description now all you have to do is
push down on the little tab and the switches slide right out now this is
what you want to replace right here and this says three eight and twenty five
see that doesn’t really matter it also says F a 63 that also doesn’t
really matter the key is the orientation of these little tabs and what this
switch does again you can hear this clicking I think it’s good and I know
it’s a good switch if this was fused and you tried to push it in and it winds
more than clicking there’s the metal is fused in here and it’s broken and here’s
a key do not buy the official maytag whirlpool whatever switch you don’t need
it there you can get them for as little as four or five or six bucks you don’t
have to bite the $30 switch just know if it’s normally open normally closed or
the the three-way where it switches back and forth that’s all you need to get and
you can tell by the plugs so when you take it off say okay there’s a plug on
the bottom and them on the front or is there two on the front or they’re three
plugs that’s all you need to know and that’s what you need to replace just
plug it back in and you’re good to go again if you’re not sure it’s good to
take lots of pictures with your cell phone so you know okay the blue and the
white wire goes here okay the orange wire goes here cuz you’re gonna forget
in a couple weeks so it’s good to take lots of pictures and mine there’s two
holes in these switches there’s two prongs they fit in and it clicks right
in so the last problem is the f1 key for air and this is where you might want to
consider replacing your microwave because it gets a little complicated the
problem is in this circuit board it’s a relay f1 e4 is a power relay issue first
of all check those two other things I had to recommend cuz those are cheap
quick fixes that you can do once you get into this area you might have a problem
you can either one by the circuit board which might end up being 60 $100 – you
could try to replace this relay right here I mine it says H it’s kind of hard
to see I had to get in here with my cell phone
it says H F 6046 F and it’s welded in you would have to
take this circuit board off d solder it and replace it if that’s the issue this
is the main relay so it might be this problem and you might be able to test it
with a digital voltmeter to see if there’s continuity you should hear it
switch on when it’s applied power to it it’s a switch that opens and closes with
power so you could test it before you have to replace it but that’s what you
want to do you might be better off buying a whole new circuit board you
might also be better off buying a whole new microwave so again if your microwave
is completely dead it’s the fuse if you’re having an issue at the door it
says door ere the lights hang on the fan stain I’m not shutting off it’s an issue
with one of these three door switches if you see f1e for error
it’s a problem with that main relay and that’s where you really get into issues
whether you should replace the microwave if you can D solder and install a new
relay which might not be the issue usually it’s one of the two easier ones
so I recommend trying that first I hope this helps I hope your microwave is
similar again this fuse might be here here it’s usually up in a main panel
that’s easy to get you you could if you knew or twice you can fix it in under
three minutes you take it off a couple screws popping and infuse you’re done
the switches are a little more complicated but again don’t have to buy
your specific brand your exact model just know if it’s normally open normally
closed or the three-way buy one for five bucks
I’ll put descriptions and links to everything down in the description below
where you can buy it even the the relay which was kind of hard to find luckily I
didn’t have to fix that I had the f-18 for air but I fixed it
with the door and the fuse so I hope this helps let me know if you have any
other questions thanks you well I hope you liked the video you just

  1. I had an issue with the microwave staying on after door was opened. Replaced the three door switches, made sure all wires were put back in the correct place and it blew a fuse right when I plugged it in. Any idea what would cause that? Switches were the same type as old ones.

  2. My Whirlpool microwave (2 years old) has an issue where the interior light flickers and it often won't turn on when this happens. I can usually get it going by opening and closing the door a few times. I suspect that it's a door switch problem. Any ideas on other potential causes?

  3. Ok 1st great video here is my dilemma. When door is close the light stays on and the plates spins however when try to set a time to cook it just beep and won't perform. I have change the fuse and that did nothing. Could this be a switch issue?

  4. I get the open/close door error but not all the time. I was advised to replace spring. Is it possible that that is the problem? Great video btw

  5. Hey @Dave Wirth I have a GE – opening and closing of the door causes either the breaker to pop or the fuse to blow.

    I've tested all three of the door switches and they all seem to work as specified – they have continuity when they're supposed to, and they lose continuity when they're supposed to.

    I've checked all the thermal fuses and they appear to work fine.

    Any ideas?

  7. Frigidaire gallery totally dead replaced main fuse. Powered back up but when turned microwave on to heat food it immediately blew a fuse again.

  8. Thank you; the control broad seams to work, but get the error of ( open and close the door)
    I checked the top switch and it works,
    I didn't check the other two switches. I will try that next.,

  9. Great video thanks for sharing. My whirlpool microwave light flickers and I hear clicking noise when I open the door. Do you think I just need to replace the door switches? Thanks again!
