What LOCK ON
actually means.
On the Microwave-In-A-Drawer, a three-second hold on Control Lock freezes both the keys and the automatic drawer, open or closed, so the drawer cannot move while you clean it. Dacor's countertop and hood models lock only the keys and show LOCK or CHILD LOCK when you touch one.

What to do when LOCK ON shows on the microwaveKind 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
On the drawer, touch and hold Control Lock for 3 seconds until the lock turns off.
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 Dacor's own guidance for LOCK ON on its microwaves. Follow it to the end: the last card says whether this is a visit.
On the drawer, touch and hold Control Lock for 3 seconds until the lock turns off.
On the PCOR30S, touch HELP GUIDE, the number 1 and STOP/CLEAR; on the slim DMO30U970S, use More Functions to turn Lock off.
If the drawer still will not move once unlocked, check the breaker and book a visit for the drawer mechanism.
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 locked drawer is not a failed drawer motor, even though neither moves the drawer. LOCK is also not a message about the door latch or the high-voltage parts.

Mode, not a failure 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 Dacor's own words
The drawer can be locked in either the open or closed position.

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.
