Microwave Hood combo not powering on
« on: February 14, 2010, 09:48:02 PM »
The microwave is about 6 years old and just died this weekend.  We did have the breaker pop.  It was reset and there is still power to the outlet.  The unit still won't power on.  Are there fuses in the unit?  Any other suggestions?

Model MH8150XMB0

If you have absolutely nothing in the machine working then the 20 amp line fuse is probably blown.

How do I replace that? Or can I? This fuse is in the microwave correct?

Unplug the microwave. Open the control panel on the right front. Look carefully for the fuse block,probably up high on the right side. There may also be another fuse on the control board.
There should also be a schematic just inside the control panel opening.

That 20 amp barrel fuse(gray in behind the small black disc) is what kills power to everything and that round black thing in front is a cavity limit, it protects the electronics by shutting down before the heat gets too bad. Before you change that fuse check your magnetron. If it has continuity from either of the 2 terminals to the metal frame then you needs ta replace the mag or the fuse will continue to blow. Also if the capacitor or diode is shorted that fuse will blow.
