(a)  Do not operate or allow the oven to be operated w ith  the  door open. 

(b) M ake the following safety  checks on all ovens to be serviced before activating the m agnetron or other m icrowave 

source, and  m ake repairs  as  necessary: (1)  Interlock  operation, (2)  Proper door closing, (3)  Seal and  sealing 

surfaces (arcing, wear, and other dam age), (4) Dam age to or loosening of hinges and latches, (5) Evidence of 

dropping or abuse.

(c)  Before  turning on  power  to  the m icrow ave  oven  for any service test or inspection within  the  m icrowave 

generating com partm ents, check the m agnetron, wave guide or transm ission line, and cavity for proper 

alignm ent, integrity, and connections.

(d) Any defective or m isadjusted com ponents in the interlock, m onitor, door seal, and m icrowave generation and 

transm ission system s shall be repaired, replaced,  or adjusted by procedures  described in this m anual  before  the 

oven is released to the owner.

(e) A m icrowave leakage check to verify com pliance with the Federal perform ance standard should be perform ed on 

each oven prior to release to the owner.

PRECAUTIONS TO BE OBSERVED BEFORE AND 
DURING SERVICING TO AVOID POSSIBLE
EXPOSURE TO EXCESSIVE MICROWAVE ENERGY
