Question about Kenmore Microwave Ovens
I was defrosting some beef and all of a sudden I lost power.The breaker is fine and there is power to the outlet.Is there a fuse in it that may have blown? mike
There is an internal fuse, plus one or two thermostats or thermal cutouts.
You can probably find an exploded view by entering your FULL model number here: http://www.searspartsdirect.com
There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
