Replace with 20A relay. Also,be very careful when removing safety-switches. They are alignedso mark the position before removing the assembly - otherwisehave a few boxes of fuses handy. sighAlso, some newer sets have realized that relays are getting moreexpensive than 20A triacs so you're bound to see some of those.
Theyare pretty reliable. It helps to clean the connectors - oxidationis not good (heating).I've also seen wires twist and 'blow' much like the fuse. It'susually around the safety-switch. Seems that some microswitceshave high resistance, they heat, the connector heats - oxidizesfaster, connections deteriorate, more heating, 'PUFF'.And don't forget the thermal switches! They can open and staythat way and make you climb up the wall. Check them if none of theabove is the problem.Microwaves are suprisingly simple.
Especially to repair. I shouldconfess that I don't really understand how the magnetron works - inthis case, taking one apart didn't help (well, I did get 2 nicemagnets for the fridge;-)Take care.-+-Filip 'I'll buy a vowel' Gieszczykiewicz E-mail: for a peek at new sci.electronics FAQ V2.0 ftp to and get file /pub/cookbook/contents.

Litton Industries was a large defense contractor in the United States named after inventor Charles Litton, Sr..
During the 1960s, the company began acquiring many unrelated firms and became one of the largest conglomerates in the United States. At its peak, in addition to many defense related companies, it also owned both Royal Typewriters and Adler, Moffatmajor appliances, Stouffer'sfrozen foods, and various office equipment and furniture companies.
Like many conglomerates, the company suffered significant declines in the 1970s, selling off many of its unrelated brands and had largely returned to its defense roots by the 1980s. The company continued to shrink after the ending of the cold war and by the late 1990s was a corporate takeover target. The company was purchased by Northrop Grumman in 2001.
History[edit]
Litton started in 1953 as an electronics company building navigation, communications and electronic warfare equipment. They diversified and became a much bigger business, with major shipyards, and manufacturing microwave ovens.
In the early 1990s, Litton Industries split into separate military and commercial companies. The US$2 billion commercial business, which included Litton's oilfield services, business and automated assembly line operations, was named Western Atlas, Inc.
The early 'li' logo was designed by Robert Miles Runyan, but was modified in 1986 by designer Gregory Thomas after a worldwide comprehensive study and analysis of the corporate identity. For much of the early 1980s and 90s, 'li SWEDA' and 'li COLE' were commonly found on product goods but it was modified to bring emphasis to the parent company, whose name was little known.

In 1998, Litton Industries bought TASC, Inc.. In 2000, TASC sold three stand-alone commercial operations: Adesso Software, WSI (Weather Services International) Corporation[1] and Emerge. In 2001, Northrop Grumman bought Litton Industries.
