20 Most Recent Viking DMOS200 1100 Watts Microwave Oven Questions & Answers

I'm guessing that's a VMOS200?

If so, that's a rebranded Sharp R-530ES (as is the Dacor DMO2420S) and its secondary interlock (bottom door switch) or that switch's mount is bad.

See this file on door switches. If you only need a switch, you can order a universal type here for $5 postpaid.

The Sharp R-530E service manual will aid you in disassembly and it is here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I don't have a manual but I know from experience that a switch is a switch. Disconnect wires from interlock switch place ohmeter on each side of switch terminals. with door closed ohmeter should read o.o ohms (continuity) with door open the ohmeter should read infinity (open circuit) Also if fuses are good but display is dead have to check for control voltages from power circuit, usually around 15 VDC. Sometimes computer circuit goes out from surge in power. There is no fix other than to replace computer/control circuitry.
Relays are checked by knowing which terminal energize the coil and doing a continuity check. The contacts can only be visually inspected. (relays only fail after thousands of cycles maybe millions!)

SADLY NO WE DO NOT

Could be shorted wiring in the door interlock

1. Open internal fuse 2. Magnetron failure 3. Control board failure 4. Door interlock failure

Might be the transformer or the control circuit that pulses the supply to the transformer at various rates depending on the power setting selected. I would suggest you first check the transformer is receiving a good supply before you spend more money. Beware of the transformer secondary that, if it is working, produces a dangerously high voltage (typically 2 - 3000 volts) that is far beyond the capability of most multimeters.

Contact a microwave specialist to assess the problem!

is it not heating in the bake or microwave mode?

MICROWAVE D 93

Clean faty strains inside then the fuse

I would need more information to help you. Please e-mail me through my Web site with your full model number and detailed symptoms. Ed Miller http://www.microwavecontrol.com

VMOC205SS The secondary interlock relay on your control board is shorted. I do board repairs, and the cost would be $69.95, which includes insured return shipping. If you would like more information, feel free to e-mail me directly or visit my site. The service manual is here, and that will help you with disassembly. http://www.microwavecontrol.com/viking_dmoc205ss_vmoc205ss_sm.pdf - Ed Miller [email protected] http://www.microwavecontrol.com

it could be a diode a cap a switch a fuse or your magnetron you can test it by your self with avo meter good luck
