What DEMO ON
actually means.

Sharp drawers have a demonstration mode for showrooms. In it the display works and the time counts down fast, but the drawer does not heat. It is switched on and off from the HELP/SETTINGS pad (TIMER/SETTINGS on newer drawers).

What to do when DEMO ON shows on the microwave

Kind of codeMode, not a failure

Something was switched on rather than something wearing out: a child or control lock set by a long press on the wrong pad, after which no key answers, a demo or showroom setting that lights the display and turns the plate while nothing warms, a Sabbath setting that dims the panel and mutes the beeps, or a clock left blinking after an outage that holds the keypad until it is set. No part is needed; a key sequence from the manual switches it off again.

Usually leads toNo repair

Touch HELP/SETTINGS five times until the display asks DEMO OFF? (TIMER/SETTINGS eight times on the SMD2489ES).

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 DEMO ON on its microwaves. Follow it to the end: the last card says whether this is a visit.

01

Touch HELP/SETTINGS five times until the display asks DEMO OFF? (TIMER/SETTINGS eight times on the SMD2489ES).

02

Touch START/+30 SEC to confirm.

03

Test with a cup of water; if it still does not heat with demo off, book a visit.

Cleared?

The code has gone and a mug of water heats again without a new part. If it comes back this week, or the food starts coming out cold in the middle, mention in the booking that it came back.

What not to do

A drawer in demo mode is not broken, even though nothing gets warm. Sharp lists demo mode as a cause of both a drawer that will not operate and food that is not heated.

Questions
about DEMO ON.

Can I clear DEMO ON myself?
Touch HELP/SETTINGS five times until the display asks DEMO OFF? (TIMER/SETTINGS eight times on the SMD2489ES).
Why does my new Sharp drawer count down fast but not heat?
It is probably in demo mode. Turn it off from the settings pad and test again.
How do I turn off demo mode on a Sharp SMD2489ES?
Touch TIMER/SETTINGS eight times, then START/+30 SEC when DEMO OFF? appears.
Can a Sharp drawer go into demo mode by itself?
It is set from the settings pad, so it is usually left on from a showroom or turned on by accident.

Back to your everyday

Still showing DEMO ON?

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.
