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). Sharp microwave display What to do when DEMO ON shows on the microwave ### Kind of code Mode, 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 to No repair Touch HELP/SETTINGS five times until the display asks DEMO OFF? (TIMER/SETTINGS eight times on the SMD2489ES). ### Shows up as What 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. ### Make Sharp Sharp microwaves repaired in the kitchen, including drawer models under the counter, countertop units and those mounted over the burners. ### Source Sharp SMD2470AS / SMD2470AH / SMD3070AS Microwave Drawer operation manual Printed in the SMD2470 / SMD3070, SMD2480 and SMD2489 drawer manuals. ## 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. ## What you may notice with it. The microwave problems DEMO ON tends to arrive with. Answer these at the microwave before anyone is booked.

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. --- **[Read on the site: Sharp DEMO ON: the drawer is in showroom mode and will not heat](https://microwaverepair.center/error-codes/sharp-demo-on/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
