The "H97" error means that the microwave's inverter has shorted out and does not work any more. The microwave cannot transfer power to create heat, and the part has malfunctions and requires replacement. Use your microwave serial number and Panasonic customer service to find the proper part for the microwave.
Microwaves are a quick, convenient
solution to the hassle of preparing and cooking hot dinners. They are
popular appliances with students and large families where food often
needs to be prepared fast. Microwaves use radio wave technology
harnessed through an antenna, known as a "magnetron," to create friction
between food or liquid molecules, causing them to heat up. Some
microwaves can cease to function properly, resulting in the appliance
running but failing to produce any heat.
Magnetron tubes are often the
source of heating problems in microwaves. Before having any repair work
done, check the warranty on your microwave. Many companies offer 10-year
warranties on magnetron tubes so you may be able to get it repaired
professionally for free. Otherwise, unplug the microwave then remove the
rear casing with a screwdriver. Locate the tube inside the microwave
and check it for burn marks. A burnt tube cannot usually be repaired
and will require replacement. A tube that doesn't appear burnt should be
tested by a qualified technician to see if it can be repaired.
High Voltage Capacitor
A microwave capacitor holds
electricity as the appliance is running. A malfunctioning capacitor can
lead to the microwave not heating, along with an irritating buzzing
sound. Test the capacitor by first disconnecting the power then removing
the wires attached to the capacitor. A capacitor with burn marks is
usually damaged beyond repair and will require replacement. A capacitor
can be tested by connecting each of the probes of an ohmmeter to the
capacitor terminal. Each probe should provide a reading of infinity if
the capacitor is working properly.
The diode in a microwave oven is
a one-way pathway that channels electricity from the capacitor. A
malfunctioning diode can sometimes be the cause of a microwave that
won't heat. The heating problem is often accompanied by a loud buzzing
noise. You can test the diode by first unplugging the microwave oven,
disconnecting the diode from the capacitor then measuring the level of
electricity inside the diode with an ohmmeter. The ohmmeter can
determine whether the electricity in the diode is flowing in one
direction as it should. In most cases, the magnetron tube will have to
replaced as well if the diode is damaged.
Disconnecting the plug from your
microwave to carry out an inspection does not guarantee safety. Even an
unplugged microwave still has electricity running through its
components, which can lead to severe electric shocks. Unless you have
previous experience in dealing with electrical appliances, it is
advisable to hire a technician to test component parts rather than
undertake the job yourself. Anyone without a basic knowledge of
electrical currents and safety should avoid testing components

I have broken microwave. and repair guys won't change parts to fix. so i am willing to change it myself.
one of them has no heat..
any help and manuals?
The magnetron is the most likely cause, "heats food" this part is the heart of the microwave and expensive. The other two parts to consider is the high voltage capacitor and diode, but repairs will run high depending on the nature of the problem.
GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.
