Does this unit have a grease filter? Sounds like the fan only runs occasionally
For model number LCS2045WBK
Hi Kim, thank you for contacting us. We have researched the model and could not find any separate grease filters. The base plate, part number PS3554778, has vents on it. For the fan issue, we would recommend checking the fan motor, part number PS3622259, and the fan blade, part number PS3528612. We hope this information is useful!

My microwave shut off while in use. Now there is no power (no display clock or anything). I've checked the outlet and it has power. Is there a fuse? Is it a blown fuse ? Is it replaceable? What else could it be? Is it worth fixing or buy a new one?
For model number LCS2045WBK
Hi Marc, thank you for getting in touch. Yes, there is a main inline fuse, part number PS3522743, in your model. The function of this part is to shut off the microwave if there is a power surge in order to protect your microwave from damage. You may need to replace it to fix the issue. We hope this sorts out your problem!

Motor Burned Out On Turntable
My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No tri
