Hi. I live near Rio, but I can easily contact a repair service in Salvador by phone or email and schedule their visit to the location where you are. I will need to know the make and model of the stove (in Brazil, each manufacturer keeps in touch with different repairmen in each town, so not all of them attend all brands of stoves), and the location and contact (phone or email) of where you are. Since I don´t live in Salvador and don´t know the repairmen personally, I can´t guarantee the quality or prices of their work, but I can make the contact today for $10. Please contact me, and let´s get your problem resolved. Thanks, David
