One and a half hour into self-cleaning my oven lost complete power.The breaker did not trip. This has happened to me before, the only difference this time is I am doing the repair myself. I have installed a new thermal fuse (4451354) and still do not have power. What would you recommend me replacing next. I did notice that I replaced fuse 4451354 and the repair tech that came out last time replaced 4456654. Are these the same fuses?

Shawna for Model Number RBD305PDB15

ANSWER Hello Shawna, You would want to check to see if you are getting power to the control board. If you do a voltage check on P24 pin 3 to pin 1 you should have 120vac. If you do not have 120 vac then you need to check your power supply since you have already replaced thermal fuse. If you do have 120vac then you need to check connector P16 pin 5 to 7 for 120 vac. If you do not have 120 vac at this point then you need a control board. If you do have 120vac then you need to check connector 16 pin 2 to 3 for 12vdc. This is your transformer line. If you do not have 12 vdc then you would need to replace transformer 9760587. If you do have 12 vdc at this point then you need to replace control board W10406070. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
