Microwave oven (american home)

Post by Lenaren on Wed Mar 06, 2013 9:53 pm

Master patulong naman... microwave oven po hindi umiinit at may konting amoy sunog...

Ano po ba posibleng sira nito?... ung magnetron ba o transformer?

Normal lang po ba na umiinit ung transformer? Napansin ko po kasi mainit na mainit ung base ng transformer...

May diagram po ba kayo nito sis??? Thanks!!

Eto po nakalagay sa unit...

American Home MD-701BMR-1

Sadya ba talagang mainit ang base ng HV transformer master?

BTW OK naman po lahat ng mga switches... Ung pinalitan ko lang ay ung plate motor kasi di na naikot...

Sinubukan ko kasi sis na i-ON ang unit... may naaamoy me parng sunog na wires... kaya duda ako baka may tama na ang HV Trafo... mainit kasi... di pwede hawakan ng matagal sa ilalim ng base nito...

BTW sis salamat pala sa tips.... 1+ sa u... Smile
