Sounds like you missed checking the outlet and it's connections. If
wires are backstabbed remove them and attach them using the screws.
Actually, just replace the outlet in case it has a faulty connection,
but use the screw terminals to attach the wires.

It takes two wires to make this circuit work. The hot leg is apparently
fine, the neutral is apparently open. Either the neutral of a two wire cable
is loose in the panel feeding the circuit, or the neutral conductor of a
multiwire branch circuit is loose in another outlet box, which is feeding
the microwave outlet, or the neutral connection to the microwave outlet is
open

Outlet, wire or breaker For about $5.00 and an hours time you can
replace the two most likely culprits and dont even worry about which
one was bad.

1) Bad connection at the socket
2) Neutral wire is loose
3) Corrosion on the metal bar, where the breaker gets its
power
Friend of mine had an air conditioner socket that did much
the same thing. Turns out the white wire was loose, where it
screws into the neutral bar.

Why would the below be happening?
1. 12 year old over the range microwave stopped working - no
power.
2. Microwave on its own dedicated 20 amp circuit.
3. No other outlets or devices on this circuit.
4. The circuit breaker was NOT tripped.
5. Reset the breaker several times (off-on-off). Power
restored to the
microwave (enough to display the clock), but as soon as you
try to
cook something the microwave looses power and the circuit
panel
breaker is NOT tripped.
6. Assumed the microwave was bad and bought a new one.
7. Exact same problem with the new microwave.
8. Recycled the breaker several times to get power to the
microwave
again (so the clock displays), but did not try to cook
anything.
Unplugged microwave and plugged in a hair dryer. Tryed to
run the hair
dryer - no power and circuit breaker NOT tripped.
9. Microwave works perfectly when plugged into another
circuit.
10. Assumed the circuit breaker itself was defective.
11. Replaced the circuit breaker with a new one and still
have the
exact same problem.
So now logically, it seems that the only problem it could be
something with the wiring itself. This circuit has worked
without
problem for the last 12 years.
Could someone provide some guesses as to what the problem
might be?
Thank you,
Jess

sure sounds like a high resistance connection to me.
is the 'wave hardwired, or is it plugged into a receptacle? (I suspect
either a bad backstab recep connection, or a poor connection between
recep and plug)
have you tried plugging the 'wave into a different recep?
