Microwave keeps losing power

Recently, I've been having problems with my microwave. It's about 7-8
years old and is plugged into a grounded 3 prong outlet. The problem
is that when I go to hit the start button, it cuts off and on very
quickly (loses power). I can tell that's what happened because the
clock resets. Other than that, it works fine.

When this problem happens, there doesn't seem to be any other
electrical equipment running that would cause a problem. It's just
typical stuff like a tv, refrigerator, and the heat. I suppose the
heat cutting on and off could cause it but it's hard to tell. This
doesn't happen often and usually happens when someone hits the start
button. Sometimes it will happen several times in a row.

Does anyone have any ideas what could cause this problem?

I'm guessing but it sounds like the power supply is knackered. It may need a new
storage capacitor.

Sounds like you have a high resistance connection somewhere, I'd start
by checking the fuse holder and door interlock switches. Something is
probably arcing when the high load of the power transformer kicks in.

Plug it into a different outlet.

I'd switch outlets first. Start current is high and if your house is
wired with the push-in "fast and easy" receptacles they will often die
under high current. The screw connections on receptacles make a much
better connection for high current.

Next idea would be to take it apart and look inside. They use push on
fast connects and those things can fail. Aside from obvious charred
wire, check each one and pull them off (after unplugging the uW and
discharging the cap - with an insulated screwdriver!). If one is a
different color than the others it could indicate it is running hot
with a poor connection.

Check the interlock system as well. It wouldn't seem like an
interlock could cause the clock to reset but it can when rapidly
pulsing the load.

Brown-out can cause it - but you'd see the lights on that circuit
flicker when the uW starts.

Then it is on to the components - but more likely just a bad
connection somewhere in the primary power circuits.

Get a qualified tech to repair it. I'd check the door switches first. Note
that these will KILL you faster than anything else you might try to repair.

After 8 years it really is time to buy a new one.
You have had your monies worth

Here's how you use a microwave stupid, you enter the time, usually
printed on the TV dinner carton, and then you press start.

Just user error

Yeah, like I said, you have to put in the time then press start,
Taylar's ****.

What the **** do you think those numbers on the keypad are for making
phone calls?
