‘’HINT’’
PROCEDURE FOR DETERMING WHETHER THE FRONT MAGNETRON CIRCUIT OR REAR MAGNTRON
CIRCUIT IS DEFECTIVE.
SYMPTOM:One magnetron does not work giving less than normal heat.
Caution:
Make sure that cabinet(outer wrap) and rear plate are not removed from the oven for your safety.
1.Operate oven as follws.
1) Remove the lead wire on the primary winding of high voltage transformer for front magnetron.
2) Place a cup of water in the oven.
3) Close the door.
4) Touch “ CLEAR” , “TIME”, “5” , “0” and “ “ key to operate the oven for 50 seconds with full power level.
5) When water is warm, the circuit of rear magnetron is normal.
When water is still cool, the circuit of front magnetron is defective.
