WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before

operating.

Failure to do so can result in death or

electrical shock.

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.

Make the following safety checks on all ovens to be serviced

before activating the magnetron or other microwave source,

andmake repairs as necessary:

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 microwave power for any service test or

inspection within the microwave generating compartments,

checkthe magnetron, waveguide or transmission line, and

cavityfor proper alignment, integrity and connections.

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service manual before the oven is released to the owner.

A microwave leakage check to verify compliance with the Federal

Performance Standard (CSA in Canada) should be performed on

each oven prior to release to the owner.

Do not attempt to operate the oven if the door glass is broken.

FOR SERVICE TECHNICIAN’S USE ONLY TROUBLESHOOTING 3. 4. Do not continue with the diagnostics of appliance if the household fuse is blown, a circuit breaker is tripped, or if there is less than 120-volt power supply at the wall outlet. Complete the following steps before checking microwave oven circuitry: 1. Unplug microwave oven or disconnect power. 2. Discharge high-voltage capacitor and disconnect white wire from power transformer. Check for loose wiring or incorrect wiring within microwave oven.
