see this causes and fix it. God bless you
No Lights or Power, Unit seems Dead First check is the main
fuse of the unit. On countertop units, you will need to take the shell
off. The fuse will be close to where the cord comes through into the
unit. OTR units, this main fuse is usually behind the control panel or
possibly behind the vent. Usually the fuse is obvious if blown,
otherwise test with an OHM meter, if open, replace fuse.Some
brands will also have a thermal cut-off fuse in the incoming voltage
line to the control board. Older Maytags and Samsungs have this fuse in
it. This thermostat looking fuse is usually above the oven cavity
somewhere under the outside shell. Sometimes you can get to it through
the vent of OTR models. Test with an OHM meter, replace if open.
Touchpad dead If
you have a stuck key or non-responsive key, most of the time you will
have to replace the keypad for this microwave oven repair. If your
keypad is connected to your control board by a flat ribbon wire, try
disconnecting it and clean the silver contacts with an ordinary pencil
eraser. After cleaning, plug it back in and try it. If it doesn't fix
it, replace the keypad unit. Some units actually have keypad tests to
confirm your diagnosis of a bad key.If your keypad and control is
the same unit, replace that unit. Another note, unlike stove/oven
keypads and controls, most microwaves do not have error codes or tests
to distinguish whether it is truely the keypad or control. Most of the
time, it is the keypad that needs replacing, but a small percentage of
the time it can be the control. Check the tech sheet if they can point
you to the right part.
