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

(a) Do not operate or allow the oven to be operated with the door open. 
(b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave 

source, and make repairs as necessary: (1) Interlock operation, (2) Proper door closing, (3) Seal and sealing 
surfaces (arcing, wear, and other damage), (4) Damage to or loosening of hinges and latches, (5) Evidence of 
dropping or abuse.

(c) Before turning on power to the microwave oven for any service test or inspection within the microwave 

generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper 
alignment, integrity, and connections.

(d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and 

transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the 
oven is released to the owner.

(e) A microwave leakage check to verify compliance with the Federal performance standard should be performed on 

each oven prior to release to the owner.
