Wolf builds a demonstration mode into its microwaves so dealers can show the controls without microwave power. The timer runs, often much faster than normal, and the light and display work, but the magnetron is not used. A unit left in this mode after delivery looks like a microwave that has stopped heating. Wolf microwave display · also shown as DEMO, DEMO OFF, DEMO ON - DURING DEMO NO OVEN POWER 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 On the drawer, touch SETTINGS five times, then START, and look for DEMO OFF; the drop-down door and speed oven use a similar SETTINGS sequence printed in their own guides. ### 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 Wolf Wolf microwaves looked at on site, whether the trouble is a drawer that sticks, a cavity that stays cold or a control strip with nothing lit. ### Source Wolf answer: MD microwave drawer showroom mode The MD drawer guide uses SETTINGS five times then START, and the MDD drop-down door and SPO speed oven guides print their own SETTINGS sequence ending in DEMO ON. Wolf's showroom answer for the MW24, MWC24, MS24 and MC24 describes a clock-key sequence and the long message DEMO ON - DURING DEMO NO OVEN POWER. ## Before you book, in this order. Each step comes from Wolf's own guidance for DEMO ON on its microwaves. Follow it to the end: the last card says whether this is a visit. 01 On the drawer, touch SETTINGS five times, then START, and look for DEMO OFF; the drop-down door and speed oven use a similar SETTINGS sequence printed in their own guides. 02 On the older MW24 and MWC24 or the MS24 and MC24, follow the clock-key steps in the guide for that model, or unplug the unit and plug it back in, which Wolf says also returns it to normal. 03 Heat a cup of water for one minute to prove the microwave warms again; if it still does not, 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 DEMO ON is not a failed magnetron, even though the food stays cold in the same way. It also does not explain a display that counts down at normal speed with no heat and no DEMO on the screen, which needs a technician. ## What you may notice with it. The microwave problems DEMO ON tends to arrive with. Answer these at the microwave before anyone is booked.

On the drawer, touch SETTINGS five times, then START, and look for DEMO OFF; the drop-down door and speed oven use a similar SETTINGS sequence printed in their own guides. ### My new Wolf microwave drawer lights up but will not heat. Could it be DEMO? That is the first thing to rule out. Look for DEMO on the display, and if the timer races through a minute in a few seconds, the drawer is in showroom mode. ### Will a power cut take my Wolf microwave out of DEMO mode? Wolf says unplugging and plugging back in resets the MW24, MWC24, MS24 and MC24 to normal mode. On the drawer and drop-down door, use the SETTINGS sequence in the guide. ### Can DEMO mode be turned on by accident on a Wolf speed oven? It takes several presses of Settings, a number and Start, so it usually happens in a showroom or during setup. It does no harm and turns off with the same steps. --- **[Read on the site: Wolf DEMO ON: the microwave is in showroom mode and will not heat](https://microwaverepair.center/error-codes/wolf-demo-on/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
