Fred W for Model Number Samsung Uwave SMH9187B/XAA With door closed the unit made buzzing sound which quit after a short time. Unit runs but does not heat. Noted that one 20A fuse is now open. Checked diode connected from large capacitor to chassis on 20M scale on VOM and it shows open in both directions. What else can I check? Is the 250V 20A fuse an off the shelf item? Thought I would get a new diode which you show in stock and try that. Any advice? Thanks.
Answer Fred, The fuse comes as part of the noise filter assembly which is part number DE96-00400B. As for the diode, if it was failing it could make a buzzing noise which is not uncommon. Read More... Answered by AppliancePartsPros.com | Friday, January 9, 2015
