What LOCK ON
actually means.

Every current Viking microwave can lock its panel against small hands. Depending on the model, the lock is set with Help and a number, with a long press on STOP/Clear, or with a Control Lock pad, and a touched pad brings up the lock word. On the DrawerMicro, the lock also holds the motorized drawer in place so it cannot open or close during cleaning.

What to do when LOCK ON shows on the microwave

Before you book,
in this order.

Each step comes from Viking's own guidance for LOCK ON on its microwaves. Follow it to the end: the last card says whether this is a visit.

01

On the RVM320 and RVMH330, touch Help and then STOP/Clear to cancel the lock.

02

On the VMOD DrawerMicro, hold the Control Lock pad for 3 seconds until LOCK OFF shows; on the VMDD drop-down door, hold STOP/CLEAR for 3 seconds.

03

If the lock word disappears but the pads still do nothing, switch off the breaker for a minute, restore it and book a visit if the panel stays dead.

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

The lock is not the two-step door release on the VMOC506 and VMOS501, which asks you to touch DOOR before pressing the push button while a cycle is running. It is not a touch panel failure either, as long as the lock word appears when a pad is pressed.

What you may
notice with it.

The microwave problems LOCK ON tends to arrive with. Answer these at the microwave before anyone is booked.

All problems

No repair indicated

Nothing to repair.

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.

In Viking's own words

Should a pad be touched, CHILD LOCK ON will appear in the display.

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. RVM320 shows CHILD LOCK ON, RVMHC330 and VMOC506 show LOCK, VMOD5240 and VMDD5306 show LOCK ON; the key sequence differs by model.

Questions
about LOCK ON.

Can I clear LOCK ON myself?
On the RVM320 and RVMH330, touch Help and then STOP/Clear to cancel the lock.
My Viking DrawerMicro will not open and shows LOCK ON. Is the motor broken?
Probably not. The lock holds the automatic drawer mechanism as well as the pads, so hold the Control Lock pad for 3 seconds and try Open again.
How do I unlock a Viking RVMH330 microwave hood combination?
Touch Help and then STOP/Clear, as the 3 Series manual describes. The display returns to the clock when the lock is off.
Can I turn off the two-step door release on my Viking VMOC506?
Yes. That is a separate safety feature from the panel lock, and the manual explains how to switch it off under Unlock Door in the Help settings.

Back to your everyday

Still showing LOCK 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.
