Galanz WP700AP20 - Common Breakdown of Microwave Oven and Means of Repairing; 1. When starting the oven, the lamp is not on, the turntable tray cant rotate and the food cant be heated; 2. When starting the oven, the lamp is on, the turntable rotating, the fan cycling but the food cant be heated.

PHENOMENON CAUSE REPAIRING MEANS
1. When starting the
oven, the lamp is not on,
the turntable tray can't
rotate and the food can't
be heated
SAfuse broken.
The primary and secondary winding of the
transformer arę short - circuited.
The earthing or the polarity of the polarity of
the capacitor is punctured.
The pilot switch can't cut off.
The interlock switch hasn't closed.
The power pług and the socket arę not in
good connection.
The door hook broken.
Change a new fuse.
Change a new transformer.
Change a new capacitor.
Change a new pilot switch.
Change a new interlock
switch.
Adjust the connection or
replace it by a new one.
Change a new hook.
2.When starting the
oven, the lamp is on, the
turntable rotating, the fan
cycling but the food can't
be heated.
The primary and secondary winding, the
filament of the transformer arę open -
circuit-ed.
The magnetron filament is open - circuited,
the magnetic steel of the magnetron broken
or the magnetron is air leaking.
Time and power distributor broken.
The plugs of the magnetron or the capacitor
loosed.
Change a new transformer.
Change the magnetron.
Change the time power
distributor or the
micro-switch.
Fix them.
3. The food can be
heated, but the lamp is
not on
The lamp broken.
The pług falls off.
Change a new lamp
Insertthe pług again
4. The food can be
heated but the turntable
tray is not rotating.
The turntable motor broken
The pług fali off
Connecting shaft weave broken
Change the turntable motor
Inset the pług securely
Change the weave
5. The oven can heat
within 2-3 minutes, but
can not heat from the
fourth minutes
The winding of the fan motor in
open-circuited.
The fan falls off
The pług of the fan motor falls off
The turnatable shaft is griped with the
mo-tor bearin
The cooling vent blocked
1 .Change the fan motor
2.Change the fan
3.Insertthe pług
4.Overhauling them
S.Repairing it
6. When starting the
oven, it can't heat, and
with "wenwen" noise.
The high voltage diodę was punctured
Change a new diodę
7. The oven can heat, but
with sound "shishi" noise
The iron córę of the transformer loosed Change a new transformer
8. Large amount
microwave leakage
of
The door deformed
The door metal net cracked
The gap of the door crack is too large
The welding point of the oven falls off
Mend the door
Change the door
Adjust the gap
Change the oven
