2.3. Partreplacement.
Whenanypartor componentistobereplaced, always ensurethatthepowercord isremoved
from thewall outlet.
2.4. Whenthe10Afuse isblownduetotheoperation oftheshort
switch:
WARNING
Whenthe10A250Vfuse isblownduetotheoperation ofthe
interlock monitorswitch, replace all ofthecomponents (primary
latchswitch, doorswitch, shortswitchand powerrelayB(RY1)).
1. Thisismandatory. Referto“adjustments and measurements”for
thelocation ofthese switches.
2. Whenreplacing thefuse, confirm that ithas theappropriate rating
forthese models.
3. Whenreplacing faultyswitches, besurethemounting tabsarenot

2.5. Avoidinserting nails, wireetc. through anyholes intheunit
during operation.
Neverinsertawire, nail or anyothermetal objectthrough thelampholes on thecavityor any
holes or gaps, because suchobjectsmay workas anantennaand cause microwave leakage.
2.6. Confirm afterrepair
1. Afterrepairorreplacementofparts, make surethat thescrewsof
theoven, etc. areneitherloose normissing. Microwaves might
leak ifscrewsarenotproperlytightened.
2. Make surethat all electrical connectionsaretightbeforeinserting
