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 microwaveKind of codeSensors and temperature
The control has stopped trusting what one of its sensors reports: the cook or humidity sensor that ends a sensor reheat when steam rises, or a thermal cutout that trips when the cavity or the magnetron runs too hot. A cutout that opens stops the microwave mid-cycle and often recovers once it cools; one that keeps tripping, or a sensor program that shuts off at once every time, needs the sensor, its wiring or the airflow behind it checked.
Usually leads toMicrowave control board and touchpad repair
Tracing a dead display, keys that do not answer or a code that keeps returning to the keypad, the ribbon, the relays or the main board, and replacing only the part that failed.
Shows up asWhat a Microwave Error Code Is Telling You
A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared.

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.
Press STOP/CLEAR and leave the door open so the cavity can cool.
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.
If Er03 returns on a normal cycle after cooling, book a visit so the thermal protection and fan can be checked.

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.

Sensors and temperature on other makes
Microwave hood combination
The microwave that hangs from the wall cabinets above the burners, heating food in its cavity while its own fan, light and filters handle the steam and grease rising from the pans beneath it.
Built-in microwave
A microwave set into a tall cabinet or a wall of cabinetry at eye level, either a countertop body wrapped in a trim kit or a true built-in model, including speed and convection microwaves that brown as well as heat.
Microwave drawer
A microwave built under a counter or into a kitchen island that opens like a drawer at the touch of a key, with a motor and gears sliding its cavity out toward you.
In Sharp's own words
The display may show Er03, which means the appliance has entered into high temperature overheat mode.

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.
