Question about Maytag MMV1153A Microwave Oven
Saibal, microwave repair is a dangerous endeavor if you have not been schooled on them. The antennae you mentioned is part of a larger component, the magnetron. This is a high voltage device (~5000 VAC) and is extremely delicate. Access to it must be from the inside of the cabinet so the unit must be dis-mounted from the wall and placed on a work area. BEFORE PROCEEDING... READ ALL INFORMATION LOCATED HERE!!! http://www.gallawa.com/microtech/index.html THIS WILL COVER THE DANGERS AND SAFETY PROCEDURES. After the unit is on a suitable work area, remove the outer cabinet and set it aside. Now, slow down and visually verify the location of all components... DO NOT TOUCH ANYTHING UNTIL YOU HAVE LOCATED THE HV CAPACITOR!!! After locating the capacitor, follow the instructions listed above to discharge it. Now the magnetron is safe to remove. Remove the wire harness from the magnetron. You will see the 4 fasteners which retain it, remove them and the magnetron will come out. Carefully and gently install the new magnetron and fasten it securely. Reinstall the wire harness to it and rebuild the unit. After installation, test the unit with a cup of water BEFORE reinstalling it. There is a chance that when the magnetron failed, it destroyed the capacitor and/or the HV Diode. If it heats the water, your OK. If not, you'll need the capacitor and diode. I can't stress enough how important it is to follow ALL safety procedures outlined in the link, above! Job time is approx. 2 hours. OK, parts availability... the part number you need is #58001218. I show one available through 1'st Source in Albuquerque, NM. Ph.# (505) 884-0166. List price= $90.98. The gluing technique will NOT work as a repair. The magnetron vibrates at an extremely high frequency and the dome (antennae) will shatter immediately. Please do not perform this repair this way as injury or more damage may be incurred.
