A built-in microwave in a kitchen cabinet stopped halfway through a cycle, a covered glass dish of vegetables inside behind the mesh window and a faint wisp of steam on the glass.

What Er03
actually means.

Sharp's compact convection and air fry countertop model protects itself when its temperature climbs too high. It stops, shows Er03 and sounds an alert that continues until you press STOP/CLEAR or unplug it.

What to do when Er03 shows on the microwave

Before you book,
in this order.

Each step comes from Sharp's own guidance for Er03 on its microwaves. Follow it to the end: the last card says whether this is a visit.

01

Press STOP/CLEAR and leave the door open so the cavity can cool.

02

Check that the vents around the cabinet are not blocked by walls, bags or other appliances, and that the air fry basket is not overloaded with greasy food.

03

If Er03 returns on a normal cycle after cooling, book a visit so the thermal protection and fan can be checked.

Still there?

It usually turns into microwave control board and touchpad repair. Book with the code and the model number.

What not to do

Er03 is not a fire alarm; if you see flames or smoke, keep the door shut and unplug the unit. It is also different from Er04, which is the low-temperature protection.

What you may
notice with it.

In Sharp's own words

The display may show Er03, which means the appliance has entered into high temperature overheat mode.

Questions
about Er03.

Can I clear Er03 myself?
Press STOP/CLEAR and leave the door open so the cavity can cool. If it comes back, it needs a visit.
What should I do when my Sharp SMC0985KS shows Er03?
Press STOP/CLEAR, let it cool with the door open and check the air space around it. A repeat after cooling needs a technician.
Why does my Sharp air fry microwave overheat?
Blocked vents, long back-to-back air fry or convection cycles, or a cooling fan that has slowed can all push it into Er03.
Can I silence the Er03 beep on a Sharp microwave?
STOP/CLEAR stops it, as does unplugging the microwave.

Back to your everyday

Still showing Er03?

Three details make the booking useful: the characters or beeps just as they appeared, every character of the model number, and whether a cup of water still warms up. With those, the technician arrives already halfway to the answer.
